52100 Especifica\u00e7\u00f5es do Material<\/a><\/div>\n<\/div>\n<\/div><\/div>\n<\/div><\/div>\n\n\n\n
\n

AISI 52100<\/a> \u00c9 um a\u00e7o hipereutet\u00f3ide de alto carbono e baixo teor de cromo, contendo aproximadamente 1,0% de carbono e 1,5% de cromo. \u00c9 amplamente utilizado internacionalmente em mancais totalmente temperados e aplica\u00e7\u00f5es de alto desgaste.<\/p>\n\n\n\n

As propriedades do a\u00e7o 52100 derivam tanto de sua composi\u00e7\u00e3o quanto de um tratamento t\u00e9rmico de endurecimento adequado. Enquanto o tratamento t\u00e9rmico convencional de a\u00e7os-ferramenta visa minimizar a austenita retida para evitar deforma\u00e7\u00f5es e trincas, o tratamento t\u00e9rmico do a\u00e7o 52100 ret\u00e9m intencionalmente uma por\u00e7\u00e3o dela. Quando o a\u00e7o 52100 \u00e9 utilizado em rolamentos, ele gera fadiga por contato de rolamento de alta frequ\u00eancia. A austenita residual \u00e9 especificamente projetada para suportar essa condi\u00e7\u00e3o de opera\u00e7\u00e3o. Pesquisas indicam que rolamentos de a\u00e7o 52100 contendo austenita residual de 5% a 15% geralmente apresentam maior vida \u00fatil \u00e0 fadiga por rolamento do que rolamentos sem austenita residual.<\/p>\n\n\n\n

Ap\u00f3s receberem o a\u00e7o 52100 recozido, nossos clientes devem realizar seus pr\u00f3prios tratamentos t\u00e9rmicos, incluindo o recozimento para al\u00edvio de tens\u00f5es e a t\u00eampera. O processo de t\u00eampera segue os procedimentos padr\u00e3o para a\u00e7os-ferramenta, abrangendo pr\u00e9-aquecimento, austenitiza\u00e7\u00e3o, t\u00eampera e revenido. Este documento se concentra nessas etapas.<\/p>\n\n\n\n

Tratamento t\u00e9rmico para al\u00edvio do estresse<\/h2>\n\n\n\n

Para garantir a estabilidade dimensional durante a etapa subsequente de t\u00eampera do a\u00e7o 52100, as opera\u00e7\u00f5es de al\u00edvio de tens\u00f5es s\u00e3o essenciais, principalmente ap\u00f3s usinagem pesada ou conforma\u00e7\u00e3o. As tens\u00f5es residuais de usinagem na pe\u00e7a s\u00e3o aliviadas durante o tratamento t\u00e9rmico, resultando em altera\u00e7\u00f5es dimensionais significativas.<\/p>\n\n\n\n

Procedimento operacional: Aquecer a uma temperatura entre 650 \u00b0C e 700 \u00b0C (1200 \u00b0F e 1300 \u00b0F). Manter nessa temperatura por tempo suficiente para eliminar completamente as tens\u00f5es internas. Em seguida, realizar um resfriamento lento no forno at\u00e9 aproximadamente 500 \u00b0C, seguido de um resfriamento final ao ar at\u00e9 a temperatura ambiente.<\/p>\n\n\n\n

Pr\u00e9-aquecimento<\/h2>\n\n\n\n

O pr\u00e9-aquecimento do a\u00e7o AISI 52100 previne o choque t\u00e9rmico e garante uma distribui\u00e7\u00e3o uniforme de temperatura entre a superf\u00edcie e o n\u00facleo da pe\u00e7a. Este a\u00e7o de alto carbono possui condutividade t\u00e9rmica relativamente baixa. O aquecimento r\u00e1pido pode criar diferenciais de temperatura significativos entre o interior e o exterior, aumentando o risco de fissuras no material 52100. A faixa de temperatura de pr\u00e9-aquecimento \u00e9 de 650 \u00b0C a 705 \u00b0C (1200 \u00b0F a 1300 \u00b0F).<\/p>\n\n\n\n

Austenitiza\u00e7\u00e3o<\/h2>\n\n\n\n

O objetivo da austenitiza\u00e7\u00e3o \u00e9 dissolver uma quantidade adequada de carbono e cromo na fase austen\u00edtica para garantir alta dureza ap\u00f3s o resfriamento. Simultaneamente, preserva carbonetos n\u00e3o dissolvidos finamente dispersos e distribu\u00eddos, aumentando a resist\u00eancia ao desgaste do material.\u00a0<\/p>\n\n\n\n

A temperatura de austenitiza\u00e7\u00e3o recomendada para o a\u00e7o 52100 \u00e9 tipicamente de 815 \u00b0C a 845 \u00b0C (1500 \u00b0F a 1555 \u00b0F). Mantenha nessa temperatura por 10 a 30 minutos, dependendo das dimens\u00f5es da se\u00e7\u00e3o transversal da pe\u00e7a. O superaquecimento ou o tempo de manuten\u00e7\u00e3o excessivo devem ser evitados, pois essas pr\u00e1ticas geram excesso de austenita retida e reduzem significativamente a tenacidade do material devido ao crescimento de gr\u00e3os.<\/p>\n\n\n\n

Resfriamento<\/h2>\n\n\n\n

O processo de t\u00eampera visa transformar rapidamente a estrutura austen\u00edtica em martensita. O a\u00e7o AISI 52100 pode ser temperado em \u00f3leo; a t\u00eampera em \u00e1gua \u00e9 proibida, pois a alta intensidade de resfriamento nesse processo \u00e9 altamente propensa a induzir trincas por tens\u00e3o. O banho de \u00f3leo deve ser mantido entre 40 \u00b0C e 60 \u00b0C (100 \u00b0F e 140 \u00b0F). Essa faixa de temperatura garante um resfriamento est\u00e1vel, minimizando a deforma\u00e7\u00e3o causada por choque t\u00e9rmico.\u00a0<\/p>\n\n\n\n

A agita\u00e7\u00e3o mec\u00e2nica durante o resfriamento \u00e9 essencial para garantir um resfriamento uniforme e evitar pontos fracos localizados. Quando resfriado corretamente, o a\u00e7o 52100 normalmente atinge uma dureza de 63\u201365 HRC.<\/p>\n\n\n\n

T\u00eampera<\/h2>\n\n\n\n

Quando a pe\u00e7a de a\u00e7o 52100 esfria durante a t\u00eampera at\u00e9 uma temperatura residual (entre 50 \u00b0C e 70 \u00b0C), ela deve ser imediatamente transferida para o forno de revenido. O revenido elimina as tens\u00f5es residuais da t\u00eampera, reduzindo a fragilidade do a\u00e7o 52100 e prevenindo o surgimento de trincas espont\u00e2neas. Para aplica\u00e7\u00f5es em mancais, as temperaturas padr\u00e3o de revenido variam de 180 \u00b0C a 250 \u00b0C para manter a dureza acima de 60 HRC.<\/p>\n\n\n\n

Problemas comuns e solu\u00e7\u00f5es no tratamento t\u00e9rmico do a\u00e7o 52100<\/h2>\n\n\n\n

1. Descarboneta\u00e7\u00e3o<\/h3>\n\n\n\n

A descarboneta\u00e7\u00e3o ocorre principalmente quando as pe\u00e7as reagem com o oxig\u00eanio em altas temperaturas, levando \u00e0 perda de carbono na superf\u00edcie e \u00e0 forma\u00e7\u00e3o de uma camada macia. Para prevenir eficazmente a descarboneta\u00e7\u00e3o, recomenda-se o uso de atmosferas protetoras, banhos de sal ou fornos a v\u00e1cuo durante o processo de t\u00eampera do a\u00e7o 52100. \u00c9 essencial manter uma atmosfera estritamente neutra ou ligeiramente redutora dentro do forno para evitar rea\u00e7\u00f5es de oxida\u00e7\u00e3o.<\/p>\n\n\n\n

2. Trincas de t\u00eampera<\/h3>\n\n\n\n

As trincas de t\u00eampera em a\u00e7o 52100 geralmente se originam de taxas de resfriamento excessivas ou choque t\u00e9rmico, ocorrendo com maior frequ\u00eancia durante a t\u00eampera em \u00e1gua ou quando o aquecimento ultrapassa a temperatura recomendada. Para solucionar esse problema, utilize \u00f3leo a 40-60 \u00b0C como meio de t\u00eampera. Simultaneamente, minimizar a diferen\u00e7a de temperatura entre o interior e o exterior da pe\u00e7a por meio de um pr\u00e9-aquecimento completo, juntamente com um controle rigoroso da temperatura de austenitiza\u00e7\u00e3o dentro da faixa recomendada, pode reduzir significativamente o risco de trincas.<\/p>\n\n\n\n

3. Distor\u00e7\u00e3o Dimensional<\/h3>\n\n\n\n

As principais causas de deforma\u00e7\u00e3o dimensional na pe\u00e7a de a\u00e7o 52100 incluem taxas de resfriamento desiguais e a libera\u00e7\u00e3o de tens\u00f5es residuais de usinagem durante o aquecimento. Para solucionar esse problema, recomenda-se incorporar uma etapa de tratamento de al\u00edvio de tens\u00f5es ap\u00f3s o desbaste, realizada a 650 \u00b0C-700 \u00b0C. Al\u00e9m disso, o uso de um m\u00e9todo de t\u00eampera em etapas pode proporcionar uma distribui\u00e7\u00e3o uniforme de temperatura em toda a pe\u00e7a antes do in\u00edcio da transforma\u00e7\u00e3o martens\u00edtica, controlando, assim, a deforma\u00e7\u00e3o de forma eficaz.<\/p>\n\n\n\n

4. Austenita retida<\/h3>\n\n\n\n

O superaquecimento durante a austenitiza\u00e7\u00e3o do a\u00e7o 52100 reduz a temperatura de in\u00edcio da transforma\u00e7\u00e3o martens\u00edtica (Ms), resultando em excesso de austenita retida ap\u00f3s o resfriamento. Essa estrutura \u00e9 mais macia, causando instabilidade dimensional na pe\u00e7a. A solu\u00e7\u00e3o \u00e9 respeitar rigorosamente a faixa de temperatura de austenitiza\u00e7\u00e3o de 815-845 \u00b0C. Para requisitos especiais, um tratamento criog\u00eanico profundo imediato (por exemplo, de -70 \u00b0C a -100 \u00b0C) ap\u00f3s o resfriamento pode ser realizado para promover a transforma\u00e7\u00e3o completa da austenita retida em martensita.<\/p>\n\n\n\n
