r\u00e1pido<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">O a\u00e7o r\u00e1pido (HSS) \u00e9 uma liga complexa \u00e0 base de ferro, projetada especificamente para usinagem de materiais em altas velocidades de corte. Quando usado para corte de metais em alta velocidade, gera altas temperaturas, fazendo com que o a\u00e7o comum perca sua dureza e capacidade de corte. No entanto, o a\u00e7o r\u00e1pido n\u00e3o perde sua dureza, mesmo quando aquecido a temperaturas pr\u00f3ximas ao vermelho-escuro, e mant\u00e9m uma boa dureza de corte.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-composition-and-alloying-elements\">Composi\u00e7\u00e3o e Elementos de Liga<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A\u00e7os r\u00e1pidos para ferramentas s\u00e3o compostos principalmente de carbono, cromo, van\u00e1dio, molibd\u00eanio ou tungst\u00eanio, ou combina\u00e7\u00f5es destes, e, \u00e0s vezes, quantidades substanciais de cobalto. O teor total de liga em a\u00e7os r\u00e1pidos geralmente varia de 20% a 40%. Todos os a\u00e7os r\u00e1pidos, sejam eles de molibd\u00eanio ou tungst\u00eanio, cont\u00eam cerca de 4% de cromo. Os diversos elementos de liga presentes no a\u00e7o r\u00e1pido s\u00e3o os principais fatores que determinam sua temperabilidade, alta resist\u00eancia ao desgaste, resist\u00eancia ao amolecimento t\u00e9rmico e excelente tenacidade, tornando-o ideal para opera\u00e7\u00f5es de corte industrial.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Os principais elementos de liga e seus efeitos incluem:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Tungst\u00eanio (W)<\/strong>A s\u00e9rie T de a\u00e7os r\u00e1pidos (HSS) cont\u00e9m tungst\u00eanio de 12% a 20%, al\u00e9m de cromo, van\u00e1dio e cobalto como outros principais elementos de liga. O tungst\u00eanio \u00e9 um elemento formador de carboneto muito forte, e sua adi\u00e7\u00e3o substancial produz grandes volumes de carbonetos de liga est\u00e1veis em altas temperaturas, aumentando significativamente a resist\u00eancia ao desgaste e a &quot;dureza ao vermelho&quot;. Uma das primeiras classes populares, 18-4-1 (T1), cont\u00e9m cerca de 18% de tungst\u00eanio.<\/li>\n\n\n\n<li><strong>Molibd\u00eanio (Mo)<\/strong>: A s\u00e9rie M cont\u00e9m aproximadamente 3,5% a 10% de molibd\u00eanio, com cromo, van\u00e1dio, tungst\u00eanio e cobalto como outros elementos de liga. O molibd\u00eanio, assim como o tungst\u00eanio, \u00e9 um forte formador de carbonetos e contribui significativamente para a resist\u00eancia ao revenimento e para a manuten\u00e7\u00e3o de alta dureza em temperaturas de corte (&quot;dureza vermelha&quot;). Os tipos de molibd\u00eanio s\u00e3o geralmente mais baratos e apresentam maior resist\u00eancia \u00e0 abras\u00e3o e menos distor\u00e7\u00e3o no tratamento t\u00e9rmico do que os a\u00e7os da s\u00e9rie T.<\/li>\n\n\n\n<li><strong>Cromo (Cr)<\/strong>Todos os a\u00e7os r\u00e1pidos cont\u00eam cerca de 4% de cromo. O cromo forma carbonetos (por exemplo, M).<sub>23<\/sub>C<sub>6<\/sub> e M<sub>7<\/sub>C<sub>3<\/sub>que se dissolvem facilmente em temperaturas t\u00edpicas de tratamento t\u00e9rmico, promovendo assim a temperabilidade. Tamb\u00e9m melhora a resist\u00eancia \u00e0 forma\u00e7\u00e3o de carepa em altas temperaturas de usinagem.<\/li>\n\n\n\n<li><strong>Van\u00e1dio (V)<\/strong>O teor de van\u00e1dio no a\u00e7o r\u00e1pido (HSS) varia e, tipicamente, quando o teor de van\u00e1dio aumenta, o teor de carbono tamb\u00e9m aumenta. O van\u00e1dio \u00e9 um excelente formador de carbonetos, formando carbonetos MC muito duros e resistentes \u00e0 abras\u00e3o. O aumento do teor de van\u00e1dio proporciona maior resist\u00eancia ao desgaste e dureza a quente. O carboneto de van\u00e1dio tamb\u00e9m atua como um agente refinador de gr\u00e3os.<\/li>\n\n\n\n<li><strong>Cobalto (Co)<\/strong>O cobalto \u00e9 adicionado a alguns a\u00e7os r\u00e1pidos (HSS) para melhorar a capacidade de corte e \u00e9 um importante elemento de liga em certos a\u00e7os das s\u00e9ries T e M. Seu principal efeito \u00e9 aumentar a dureza a quente, melhorando assim a efici\u00eancia de corte quando altas temperaturas da ferramenta s\u00e3o atingidas. O cobalto eleva o ponto de fus\u00e3o e pode aumentar as temperaturas de tratamento t\u00e9rmico. Embora aumente a dureza a quente, a adi\u00e7\u00e3o de cobalto aumenta ligeiramente a fragilidade dos a\u00e7os r\u00e1pidos para ferramentas. O cobalto n\u00e3o forma carbonetos, mas aumenta o efeito de endurecimento por precipita\u00e7\u00e3o de outros elementos de liga.<\/li>\n\n\n\n<li><strong>Carbono (C)<\/strong>Um alto teor de carbono \u00e9 crucial para a produ\u00e7\u00e3o de uma matriz martens\u00edtica dura e para a forma\u00e7\u00e3o de carbonetos prim\u00e1rios, ambos respons\u00e1veis pela resist\u00eancia \u00e0 abras\u00e3o. O teor de carbono varia tipicamente de 0,70% a 1,5%. Os a\u00e7os com baixo teor de carbono s\u00e3o mais resistentes, enquanto os a\u00e7os com alto teor de carbono oferecem maior dureza e resist\u00eancia ao desgaste.<\/li>\n\n\n\n<li><strong>Nitrog\u00eanio (N)<\/strong>: O nitrog\u00eanio geralmente est\u00e1 presente em HSS fundido ao ar em quantidades de 0,02% a 0,03%. Aumentar deliberadamente o nitrog\u00eanio para 0,04-0,05% com maior teor de sil\u00edcio pode aumentar ligeiramente a dureza m\u00e1xima ating\u00edvel e alterar a morfologia do carboneto.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-heat-treatment\">Tratamento t\u00e9rmico<\/h2>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Austenitiza\u00e7\u00e3o<\/strong>Quando o a\u00e7o r\u00e1pido \u00e9 aquecido a aproximadamente 840 \u00b0C, a ferrita se transforma em austenita, e alguns carbonetos de liga podem se dissolver. Quando aquecido a 1120 \u00b0C ou mais, todos os carbonetos M23C6 se dissolvem, e at\u00e9 50% de carbonetos M6C e MC tamb\u00e9m podem se dissolver. Isso dissolve o carbono na matriz de austenita, fornecendo o teor de liga e carbono necess\u00e1rios para temperabilidade, dureza a quente e resist\u00eancia ao revenimento.<\/li>\n\n\n\n<li><strong>Resfriamento<\/strong>. Ap\u00f3s a austenitiza\u00e7\u00e3o, o a\u00e7o r\u00e1pido (HSS) pode ser resfriado ao ar parado at\u00e9 atingir uma dureza pr\u00f3xima \u00e0 m\u00e1xima, mas geralmente \u00e9 temperado em \u00f3leo morno para uma remo\u00e7\u00e3o de calor mais r\u00e1pida e maior dureza. A t\u00eampera transforma a maior parte da austenita rica em carbono em martensita, mas alguma austenita pode ser retida.<\/li>\n\n\n\n<li><strong>T\u00eampera<\/strong>A microestrutura final ap\u00f3s o revenimento consiste principalmente de martensita revenida e carbonetos duros bem distribu\u00eddos. O a\u00e7o r\u00e1pido \u00e9 um a\u00e7o de t\u00eampera secund\u00e1ria. Revenimentos m\u00faltiplos podem converter austenita residual em martensita.<\/li>\n<\/ol>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-properties\">Propriedades<\/h2>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Dureza<\/strong>. A dureza \u00e9 a resist\u00eancia \u00e0 penetra\u00e7\u00e3o por um penetrador duro como diamante, medida \u00e0 temperatura ambiente. Os a\u00e7os r\u00e1pidos (HSS) normalmente cont\u00eam carbono suficiente para permitir o endurecimento at\u00e9 64 HRC. Os HSS de uso geral, como M1 e M7, s\u00e3o geralmente tratados termicamente para atingir 64-66 HRC, enquanto os HSS que cont\u00eam cobalto geralmente atingem 65-67 HRC. Os a\u00e7os super-r\u00e1pidos, particularmente a s\u00e9rie M40, podem ser tratados termicamente at\u00e9 70 HRC.<\/li>\n\n\n\n<li><strong>Dureza Quente (Dureza Vermelha)<\/strong>. Essa caracter\u00edstica \u00e9 a capacidade do a\u00e7o de manter alta dureza em temperaturas elevadas. Ela \u00e9 aumentada principalmente pela presen\u00e7a de cobalto, van\u00e1dio e molibd\u00eanio. As ferramentas de a\u00e7o r\u00e1pido (HSS) podem manter um fio de corte afiado at\u00e9 temperaturas em torno de 650 \u00b0C (1200 \u00b0F).<\/li>\n\n\n\n<li><strong>Resist\u00eancia ao desgaste<\/strong>. Isso se refere \u00e0 resist\u00eancia \u00e0 abras\u00e3o. Ela \u00e9 fortemente influenciada pela dureza e composi\u00e7\u00e3o da matriz, pelos carbonetos secund\u00e1rios precipitados (M2C e MC) e pelo volume e natureza dos carbonetos de liga em excesso. Uma dureza maior geralmente leva a uma maior resist\u00eancia ao desgaste, especialmente em condi\u00e7\u00f5es de corte abrasivo.<\/li>\n\n\n\n<li><strong>Robustez<\/strong>. O a\u00e7o r\u00e1pido (HSS) geralmente apresenta boa tenacidade, tornando-o eficaz para opera\u00e7\u00f5es de corte industrial. Ele \u00e9 notavelmente mais tenaz do que materiais de carboneto, especialmente em aplica\u00e7\u00f5es de corte interrompido. No entanto, a dureza extremamente alta e o alto teor de carboneto podem reduzir a tenacidade em compara\u00e7\u00e3o com outros a\u00e7os-ferramenta. O HSS metal\u00fargico (P\/M) oferece tenacidade aprimorada devido \u00e0 distribui\u00e7\u00e3o uniforme e fina de carbonetos.<\/li>\n\n\n\n<li><strong>Temperabilidade<\/strong>. O HSS endurece t\u00e3o profundamente que quase qualquer se\u00e7\u00e3o encontrada comercialmente ter\u00e1 dureza uniforme do centro \u00e0 superf\u00edcie.<\/li>\n<\/ol>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-classifications\">Classifica\u00e7\u00f5es<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Aqui, usamos o Instituto Americano de Ferro e A\u00e7o (<a href=\"https:\/\/www.steel.org\/\"><mark style=\"background-color:rgba(0, 0, 0, 0);color:#0693e3\" class=\"has-inline-color\">AISI<\/mark><\/a>) classifica\u00e7\u00e3o.<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>S\u00e9rie T (A\u00e7os para Ferramentas de Alta Velocidade com Tungst\u00eanio): Esses a\u00e7os cont\u00eam tungst\u00eanio de 12% a 20% e s\u00e3o designados pela letra &quot;T&quot;.
