O que \u00e9 o material H13 ESR?<\/h1>\n\n\n\n

O material H13 ESR refere-se a A\u00e7o ferramenta para trabalho a quente H13<\/a> que foi refinado pelo processo de Refus\u00e3o por Eletroesc\u00f3ria (ESR). N\u00e3o se trata de uma classe diferente, mas sim de uma vers\u00e3o de qualidade superior do a\u00e7o H13 padr\u00e3o, com limpeza interna aprimorada e microestrutura mais uniforme. As designa\u00e7\u00f5es internacionais comuns incluem 1.2344 ESR (DIN) e SKD61 ESR (JIS). Comparado ao a\u00e7o H13 convencional, o ESR H13 \u00e9 geralmente escolhido para aplica\u00e7\u00f5es que exigem maior confiabilidade, melhor tenacidade e desempenho mais est\u00e1vel.<\/p>\n\n\n\n

O que significa ESR em a\u00e7o ferramenta<\/h2>\n\n\n\n

A ESR, ou Refus\u00e3o por Eletroesc\u00f3ria, \u00e9 um processo de refino secund\u00e1rio aplicado ap\u00f3s a siderurgia prim\u00e1ria. Um eletrodo consum\u00edvel \u00e9 refundido atrav\u00e9s de uma camada de esc\u00f3ria fundida em um molde resfriado a \u00e1gua. Durante a refus\u00e3o, a esc\u00f3ria atua tanto como fonte de calor quanto como meio refinador, de modo que, \u00e0 medida que o metal fundido passa por ela, inclus\u00f5es n\u00e3o met\u00e1licas s\u00e3o absorvidas, o teor de enxofre \u00e9 reduzido e a solidifica\u00e7\u00e3o torna-se mais controlada e direcional. O resultado \u00e9 um lingote denso e homog\u00eaneo com significativamente menos defeitos internos, como porosidade, segrega\u00e7\u00e3o e cavidades de contra\u00e7\u00e3o.<\/p>\n\n\n\n

Especificamente para o a\u00e7o ferramenta H13, o ESR n\u00e3o altera o sistema qu\u00edmico da classe. Ele melhora a qualidade interna e a consist\u00eancia estrutural, o que afeta diretamente o desempenho em servi\u00e7o. O mesmo processo ESR \u00e9 aplicado a outras classes de a\u00e7o ferramenta, desde a\u00e7os para trabalho a frio, como o D2, at\u00e9 a\u00e7os r\u00e1pidos. Para uma vis\u00e3o mais ampla de como o ESR se compara ao VAR e onde ele se encaixa em diferentes fam\u00edlias de a\u00e7os, consulte nosso [link para o artigo\/recurso].

Diferen\u00e7as entre ESR H13 e H13 padr\u00e3o<\/h2>\n\n\n\n

A principal diferen\u00e7a entre o ESR H13 e o H13 padr\u00e3o reside na qualidade interna, e n\u00e3o na composi\u00e7\u00e3o.<\/p>\n\n\n\n

Em aplica\u00e7\u00f5es pr\u00e1ticas, o ESR H13 apresenta um desempenho mais est\u00e1vel, especialmente em propriedades transversais, onde os lingotes convencionais s\u00e3o tipicamente mais fracos.<\/p>\n\n\n\n

Vantagens t\u00e9cnicas do material ESR H13<\/h2>\n\n\n\n

1. Limpeza microestrutural e integridade estrutural<\/h3>\n\n\n\n

O processo ESR melhora significativamente a limpeza interna em compara\u00e7\u00e3o com o H13 fundido ao ar convencional. \u00c0 medida que as got\u00edculas de metal fundido atravessam a camada de esc\u00f3ria reativa, as inclus\u00f5es n\u00e3o met\u00e1licas s\u00e3o absorvidas e o teor de enxofre \u00e9 reduzido. A solidifica\u00e7\u00e3o direcional controlada produz ent\u00e3o uma estrutura de lingote densa e uniforme, com porosidade, cavidades de contra\u00e7\u00e3o e descontinuidades relacionadas \u00e0 segrega\u00e7\u00e3o bastante reduzidas. Essa melhoria na qualidade interna \u00e9 um dos principais motivos pelos quais o H13 obtido por ESR apresenta um desempenho mais confi\u00e1vel sob carga.<\/p>\n\n\n\n

2. Refino de carbonetos e controle de segrega\u00e7\u00e3o<\/h3>\n\n\n\n

As condi\u00e7\u00f5es controladas de solidifica\u00e7\u00e3o do processo ESR reduzem a tend\u00eancia \u00e0 segrega\u00e7\u00e3o na linha central e melhoram a uniformidade microestrutural geral, resultando em uma estrutura de carbonetos mais fina e uniformemente distribu\u00edda, com redu\u00e7\u00e3o da forma\u00e7\u00e3o de bandas de carbonetos. Quando combinado com um tratamento t\u00e9rmico de homogeneiza\u00e7\u00e3o adequado, esse refinamento minimiza a forma\u00e7\u00e3o de carbonetos grosseiros e n\u00e3o dissolvidos que podem atuar como pontos de inicia\u00e7\u00e3o de trincas durante o servi\u00e7o.<\/p>\n\n\n\n

3. Maior resist\u00eancia e durabilidade<\/h3>\n\n\n\n

A redu\u00e7\u00e3o de inclus\u00f5es e defeitos internos melhora diretamente o desempenho mec\u00e2nico. O a\u00e7o ESR H13 tipicamente apresenta maior ductilidade transversal e melhor resist\u00eancia \u00e0 falha por fadiga, especialmente sob carregamento t\u00e9rmico e mec\u00e2nico c\u00edclico. O processamento ESR tamb\u00e9m pode aumentar significativamente a tenacidade ao impacto, reduzindo a variabilidade entre as amostras de teste, o que \u00e9 importante em aplica\u00e7\u00f5es de ferramentas onde falhas imprevis\u00edveis representam um custo significativo.<\/p>\n\n\n\n

4. Propriedades mec\u00e2nicas mais uniformes e quase isotr\u00f3picas<\/h3>\n\n\n\n

As estruturas de lingotes convencionais frequentemente apresentam diferen\u00e7as direcionais nas propriedades devido \u00e0 segrega\u00e7\u00e3o e \u00e0 solidifica\u00e7\u00e3o n\u00e3o uniforme. O ESR reduz esse efeito, melhorando a homogeneidade nas dire\u00e7\u00f5es longitudinal e transversal. Assim, o ESR H13 proporciona um desempenho mais previs\u00edvel e est\u00e1vel ap\u00f3s a forjagem e o tratamento t\u00e9rmico, principalmente em se\u00e7\u00f5es grandes ou componentes cr\u00edticos.<\/p>\n\n\n\n

5. Vantagens de Processamento e Fabrica\u00e7\u00e3o<\/h3>\n\n\n\n

Os lingotes ESR geralmente apresentam uma superf\u00edcie mais lisa, reduzindo a necessidade de extenso condicionamento superficial antes de processamentos subsequentes. A melhoria na qualidade interna tamb\u00e9m aumenta a trabalhabilidade a quente, ajudando a reduzir o risco de fissuras durante a forjagem e aumentando o rendimento do material em processos posteriores, o que pode resultar em uma produ\u00e7\u00e3o mais est\u00e1vel e menores taxas de rejei\u00e7\u00e3o.<\/p>\n\n\n\n

Limita\u00e7\u00f5es e compensa\u00e7\u00f5es do ESR H13<\/h2>\n\n\n\n

1. Considera\u00e7\u00f5es Econ\u00f4micas<\/h3>\n\n\n\n

A limita\u00e7\u00e3o mais imediata do material H13 ESR \u00e9 o custo. O processo ESR \u00e9 mais lento e consome mais energia do que a fabrica\u00e7\u00e3o convencional de a\u00e7o, o que resulta em um pre\u00e7o significativamente maior. Portanto, o H13 ESR costuma ser consideravelmente mais caro do que o H13 padr\u00e3o. Essa diferen\u00e7a de custo significa que ele n\u00e3o deve ser tratado como uma atualiza\u00e7\u00e3o padr\u00e3o, mas sim como uma solu\u00e7\u00e3o espec\u00edfica para aplica\u00e7\u00f5es em que maior confiabilidade, vida \u00fatil prolongada da ferramenta ou menor risco de falhas justifiquem o custo mais elevado do material. Para ferramentas de uso geral ou pequenos lotes de produ\u00e7\u00e3o, o H13 convencional geralmente \u00e9 a op\u00e7\u00e3o mais econ\u00f4mica.<\/p>\n\n\n\n

2. Controle de g\u00e1s e limita\u00e7\u00f5es do processo<\/h3>\n\n\n\n

Embora a ESR melhore a limpeza e a uniformidade estrutural, ela n\u00e3o oferece o mesmo n\u00edvel de controle de gases que os processos a v\u00e1cuo. Como a ESR \u00e9 normalmente realizada em condi\u00e7\u00f5es atmosf\u00e9ricas, sua capacidade de reduzir gases dissolvidos, como hidrog\u00eanio e nitrog\u00eanio, \u00e9 limitada. Para aplica\u00e7\u00f5es em que um teor extremamente baixo de gases \u00e9 cr\u00edtico, processos a v\u00e1cuo, como a VAR (refus\u00e3o a v\u00e1cuo) ou a desgaseifica\u00e7\u00e3o a v\u00e1cuo, podem ser mais adequados. A ESR tamb\u00e9m \u00e9 menos eficaz no controle de certos elementos vol\u00e1teis ou residuais em compara\u00e7\u00e3o com as rotas de refus\u00e3o a v\u00e1cuo, o que pode ser relevante em aplica\u00e7\u00f5es altamente sens\u00edveis ou especializadas.<\/p>\n\n\n\n

3. Restri\u00e7\u00f5es de tamanho e risco de segrega\u00e7\u00e3o<\/h3>\n\n\n\n

A tecnologia ESR est\u00e1 sujeita a limita\u00e7\u00f5es pr\u00e1ticas no tamanho do lingote. \u00c0 medida que a se\u00e7\u00e3o transversal aumenta, o controle da solidifica\u00e7\u00e3o torna-se mais dif\u00edcil, o que eleva o risco de defeitos de macrosegrega\u00e7\u00e3o, como manchas. Para manter a qualidade interna, os produtos ESR s\u00e3o normalmente produzidos dentro de faixas de tamanho controladas, e ultrapassar esses limites pode comprometer a uniformidade estrutural que a tecnologia ESR visa aprimorar.<\/p>\n\n\n\n

4. Estabilidade do Processo e Sensibilidade de Controle<\/h3>\n\n\n\n

Em compara\u00e7\u00e3o com os processos de refus\u00e3o a v\u00e1cuo, a ESR oferece um controle em tempo real menos preciso sobre a solidifica\u00e7\u00e3o. A resposta t\u00e9rmica durante a refus\u00e3o \u00e9 relativamente lenta, o que torna o processo mais sens\u00edvel a varia\u00e7\u00f5es nas condi\u00e7\u00f5es operacionais; se n\u00e3o forem devidamente controladas, essas varia\u00e7\u00f5es podem levar a inconsist\u00eancias estruturais, como bandas ou padr\u00f5es de segrega\u00e7\u00e3o em forma de anel. Apesar dessas limita\u00e7\u00f5es, a ESR continua sendo amplamente utilizada por proporcionar uma combina\u00e7\u00e3o equilibrada de maior limpeza, uniformidade estrutural e praticidade de produ\u00e7\u00e3o.<\/p>\n\n\n\n

Aplica\u00e7\u00f5es industriais t\u00edpicas<\/h2>\n\n\n\n

1. Fundi\u00e7\u00e3o sob press\u00e3o de metais n\u00e3o ferrosos<\/h3>\n\n\n\n

O a\u00e7o ferramenta ESR H13 \u00e9 amplamente especificado para fundi\u00e7\u00e3o sob press\u00e3o de alum\u00ednio, magn\u00e9sio e zinco, onde as ferramentas s\u00e3o expostas a ciclos t\u00e9rmicos repetidos e fluxo de metal fundido em alta velocidade. O H13 convencional frequentemente apresenta falhas devido a trincas t\u00e9rmicas e degrada\u00e7\u00e3o superficial nessas condi\u00e7\u00f5es, enquanto a limpeza aprimorada e a microestrutura mais uniforme do ESR H13 ajudam a retardar o in\u00edcio de trincas e a reduzir a taxa de danos por fadiga t\u00e9rmica. \u00c9 comumente utilizado em componentes cr\u00edticos de fundi\u00e7\u00e3o sob press\u00e3o, incluindo blocos de matriz, insertos de cavidade, machos, guias, \u00eambolos, bicos e camisas de inje\u00e7\u00e3o, onde a vida \u00fatil da ferramenta e a estabilidade da produ\u00e7\u00e3o s\u00e3o fatores essenciais.<\/p>\n\n\n\n

2. Ferramentas de extrus\u00e3o a quente<\/h3>\n\n\n\n

As ferramentas de extrus\u00e3o a quente operam sob alta tens\u00e3o compressiva e temperaturas elevadas, exigindo um equil\u00edbrio entre resist\u00eancia, tenacidade e resist\u00eancia ao amolecimento. O a\u00e7o ESR H13 \u00e9 frequentemente utilizado na extrus\u00e3o de alum\u00ednio e magn\u00e9sio e, em casos mais exigentes, como ligas de cobre, aplicado em matrizes, blocos de suporte, revestimentos, pist\u00f5es e mandris usados para perfis ocos e complexos. A maior consist\u00eancia estrutural do ESR H13 ajuda a reduzir o risco de fissuras e deforma\u00e7\u00f5es sob carga e, para demandas de maior desgaste, a nitreta\u00e7\u00e3o \u00e9 frequentemente aplicada para aumentar a dureza superficial, mantendo um n\u00facleo resistente.<\/p>\n\n\n\n

3. Forjamento a quente e t\u00eampera por prensagem<\/h3>\n\n\n\n

Em opera\u00e7\u00f5es de forjamento a quente, as ferramentas devem suportar cargas de impacto repetidas combinadas com altas temperaturas de opera\u00e7\u00e3o. O a\u00e7o ESR H13 \u00e9 comumente selecionado para matrizes de forjamento, pun\u00e7\u00f5es, l\u00e2minas de corte e outros componentes submetidos a cargas elevadas, onde a resist\u00eancia a trincas e fadiga t\u00e9rmica \u00e9 crucial. Em aplica\u00e7\u00f5es de t\u00eampera por prensagem, como em pe\u00e7as estruturais automotivas, as ferramentas tamb\u00e9m devem proporcionar extra\u00e7\u00e3o de calor controlada, mantendo a integridade mec\u00e2nica, e o ESR H13 oferece uma combina\u00e7\u00e3o est\u00e1vel de resist\u00eancia, tenacidade e resist\u00eancia t\u00e9rmica que favorece tanto o desempenho da conforma\u00e7\u00e3o quanto a vida \u00fatil da matriz.<\/p>\n\n\n\n

4. Moldagem por Inje\u00e7\u00e3o de Pl\u00e1stico de Alta Precis\u00e3o<\/h3>\n\n\n\n

Embora a\u00e7os pr\u00e9-endurecidos como o P20 sejam suficientes para moldes padr\u00e3o, o ESR H13 \u00e9 utilizado em aplica\u00e7\u00f5es de moldagem de pl\u00e1sticos de alta exig\u00eancia, onde a qualidade da superf\u00edcie e a durabilidade s\u00e3o cr\u00edticas. O baixo teor de inclus\u00f5es do material ESR melhora a capacidade de polimento, tornando-o adequado para moldes que requerem um alto acabamento superficial, como componentes \u00f3pticos ou transparentes. O H13 tamb\u00e9m responde bem \u00e0 nitreta\u00e7\u00e3o, permitindo o desenvolvimento de uma superf\u00edcie dura e resistente ao desgaste, mantendo um n\u00facleo tenaz, o que \u00e9 particularmente \u00fatil na moldagem de materiais abrasivos, como pl\u00e1sticos refor\u00e7ados com fibra de vidro.<\/p>\n\n\n\n

Quando selecionar H13 ESR<\/h2>\n\n\n\n

O material H13 ESR deve ser selecionado quando o desempenho e a confiabilidade das ferramentas s\u00e3o cr\u00edticos e falhas acarretam altos custos em termos de tempo de inatividade da produ\u00e7\u00e3o, sucata ou manuten\u00e7\u00e3o. Cen\u00e1rios t\u00edpicos incluem ciclos t\u00e9rmicos severos, alta carga mec\u00e2nica ou requisitos rigorosos de qualidade de superf\u00edcie, como matrizes de fundi\u00e7\u00e3o sob press\u00e3o para alum\u00ednio, magn\u00e9sio e zinco, matrizes de forjamento a quente e l\u00e2minas de corte, ferramentas de extrus\u00e3o, como mandris e matrizes, e moldes de pl\u00e1stico de alto polimento que exigem um acabamento superficial superior. Nessas aplica\u00e7\u00f5es, o benef\u00edcio do ESR n\u00e3o se limita a uma vida \u00fatil mais longa da ferramenta, mas tamb\u00e9m a um desempenho mais previs\u00edvel e menor risco de falhas sob condi\u00e7\u00f5es operacionais exigentes.<\/p>\n\n\n\n

Quando o ESR H13 n\u00e3o deve ser selecionado.<\/h2>\n\n\n\n

O processo ESR com H13 n\u00e3o \u00e9 necess\u00e1rio para todas as aplica\u00e7\u00f5es e deve ser evitado quando o custo adicional n\u00e3o se traduz em benef\u00edcios mensur\u00e1veis de desempenho. Para ferramentas de uso geral, pequenos lotes de produ\u00e7\u00e3o ou aplica\u00e7\u00f5es com carga t\u00e9rmica e mec\u00e2nica moderada, o H13 padr\u00e3o geralmente \u00e9 suficiente e mais econ\u00f4mico. Para moldes de pl\u00e1stico sem requisitos rigorosos de polimento, a\u00e7os pr\u00e9-endurecidos podem ser uma op\u00e7\u00e3o com melhor custo-benef\u00edcio. O processo ESR tamb\u00e9m n\u00e3o \u00e9 ideal para se\u00e7\u00f5es transversais extremamente grandes, visto que a qualidade interna se torna mais dif\u00edcil de controlar em escala, e n\u00e3o oferece o mesmo n\u00edvel de controle de gases que os processos a v\u00e1cuo. Para aplica\u00e7\u00f5es que exigem n\u00edveis extremamente baixos de hidrog\u00eanio ou elementos residuais m\u00ednimos, a desgaseifica\u00e7\u00e3o por v\u00e1cuo (VAR) ou a desgaseifica\u00e7\u00e3o a v\u00e1cuo podem ser mais apropriadas. A sele\u00e7\u00e3o do material deve ser baseada nas condi\u00e7\u00f5es reais de servi\u00e7o, e n\u00e3o na suposi\u00e7\u00e3o de que o processo ESR \u00e9 sempre a melhor op\u00e7\u00e3o.<\/p>\n\n\n\n

Perguntas frequentes<\/h2>\n\n\n\n

N\u00e3o se trata de uma classe diferente, mas sim de uma vers\u00e3o de qualidade superior do H13 padr\u00e3o, com maior limpeza, microestrutura mais uniforme e desempenho mais est\u00e1vel em aplica\u00e7\u00f5es exigentes.<\/p> <\/div>

O H13 ESR \u00e9 melhor que o H13 padr\u00e3o?<\/strong>

O a\u00e7o H13 ESR nem sempre \u00e9 melhor, mas oferece desempenho mais consistente, maior resist\u00eancia e menor risco de defeitos. Normalmente, \u00e9 escolhido para ferramentas de alta carga ou cr\u00edticas, onde o custo da falha \u00e9 elevado.<\/p> <\/div>

Qual a diferen\u00e7a entre ESR H13 e H13 normal?<\/strong>

A principal diferen\u00e7a reside na qualidade interna. O ESR H13 apresenta menor teor de inclus\u00f5es, uma distribui\u00e7\u00e3o de carbonetos mais uniforme e menor segrega\u00e7\u00e3o, resultando em melhor consist\u00eancia mec\u00e2nica em compara\u00e7\u00e3o com o H13 padr\u00e3o.<\/p> <\/div>

Quando se deve usar o H13 ESR?<\/strong>

O H13 ESR deve ser utilizado em aplica\u00e7\u00f5es que envolvam ciclos t\u00e9rmicos severos, alta carga mec\u00e2nica ou requisitos rigorosos de acabamento superficial, como fundi\u00e7\u00e3o sob press\u00e3o, forjamento a quente, ferramentas de extrus\u00e3o e moldes de alto polimento.<\/p> <\/div>

Quando o VHS H13 n\u00e3o \u00e9 necess\u00e1rio?<\/strong>

N\u00e3o \u00e9 necess\u00e1rio para ferramentas de uso geral, lotes de produ\u00e7\u00e3o curtos ou aplica\u00e7\u00f5es com tens\u00e3o moderada. Nesses casos, o a\u00e7o H13 padr\u00e3o ou a\u00e7os de menor custo costumam ser mais econ\u00f4micos.<\/p> <\/div>

O H13 ESR \u00e9 mais caro?<\/strong>

Sim. O ESR H13 \u00e9 significativamente mais caro que o H13 padr\u00e3o devido ao processo adicional de refus\u00e3o. Normalmente, ele \u00e9 usado apenas quando os benef\u00edcios de desempenho justificam o custo mais elevado.<\/p> <\/div>

ESR vs VAR: qual \u00e9 o melhor para H13?<\/strong>

A ESR melhora a limpeza e a uniformidade estrutural, enquanto a VAR \u00e9 mais eficaz na remo\u00e7\u00e3o de gases dissolvidos. A escolha depende dos requisitos da aplica\u00e7\u00e3o, principalmente em rela\u00e7\u00e3o \u00e0 pureza e \u00e0s condi\u00e7\u00f5es de desempenho.<\/p> <\/div> <\/div>","protected":false},"excerpt":{"rendered":"

What Is H13 ESR Material? H13 ESR material refers to H13 hot-work tool steel that has been refined through the Electroslag Remelting (ESR) process. It is not a different grade but a higher-quality version of standard H13, with improved internal cleanliness and a more uniform microstructure. Common international designations include 1.2344 ESR (DIN) and SKD61 […]<\/p>\n","protected":false},"author":1,"featured_media":17072,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"_uag_custom_page_level_css":"","site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"normal-width-container","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"disabled","ast-breadcrumbs-content":"","ast-featured-img":"disabled","footer-sml-layout":"","ast-disable-related-posts":"","theme-transparent-header-meta":"","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"set","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"footnotes":""},"class_list":["post-14746","page","type-page","status-publish","has-post-thumbnail","hentry"],"yoast_head":"\nWhat Is H13 ESR Material?
