Tratamento t\u00e9rmico do a\u00e7o ferramenta M3<\/h1>\n\n\n\n

A temperatura de t\u00eampera, o meio de resfriamento e a resposta ao revenimento do a\u00e7o r\u00e1pido M3 em ambas as classes, conforme a ficha de origem publica. Um resumo de refer\u00eancia da pr\u00e1tica publicada e n\u00e3o uma especifica\u00e7\u00e3o da Aobo Steel.<\/p>\n\n\n\n

M3 no grupo dos a\u00e7os r\u00e1pidos<\/h2>\n\n\n\n

O M3 \u00e9 um a\u00e7o r\u00e1pido ao molibd\u00eanio-tungst\u00eanio, o grau que a oficina procura quando uma ferramenta de corte precisa manter o fio em alta velocidade e suportar o calor que vem com ela. A fonte o publica em duas classes e rotula as duas fichas como M3-1 e M3-2, e esses s\u00e3o os r\u00f3tulos usados nas tabelas abaixo. A diferen\u00e7a entre as classes est\u00e1 no carbono e no van\u00e1dio. A classe 1 cont\u00e9m 1,05% de carbono e 2,50% de van\u00e1dio, a classe 2 cont\u00e9m 1,20% de carbono e 3,00% de van\u00e1dio, e cada classe tem sua pr\u00f3pria temperatura de t\u00eampera e sua pr\u00f3pria linha de revenimento.<\/p>\n\n\n\n

A ficha \u00e9 informa\u00e7\u00e3o de refer\u00eancia para a oficina e n\u00e3o uma especifica\u00e7\u00e3o. Ela apresenta uma etapa de pr\u00e9-aquecimento, uma temperatura de t\u00eampera e um meio de resfriamento para cada classe, depois uma tabela de revenimento com um \u00fanico valor de dureza em cada linha e nenhuma faixa de toler\u00e2ncia em lugar algum. Vale a pena testar uma primeira ferramenta cortada de uma nova corrida de a\u00e7o antes que o ciclo seja aplicado a uma ferramenta de produ\u00e7\u00e3o.<\/p>\n\n\n\n

A ficha apresenta um \u00fanico valor para cada elemento em vez de uma faixa de especifica\u00e7\u00e3o. O cobalto aparece para ambas as classes e o enxofre para a classe 1 sem valor, portanto essas linhas s\u00e3o omitidas da tabela em vez de mostradas como zero. Um valor de enxofre \u00e9 impresso, 0,27% na ficha da classe 2, que est\u00e1 muito acima do teor de enxofre normalmente especificado para a\u00e7o r\u00e1pido, por isso n\u00e3o \u00e9 levado para a tabela e \u00e9 registrado aqui conforme a fonte o imprime.<\/em><\/p>\n\n\n\n

Ambas as classes cont\u00eam 6,00% de tungst\u00eanio e 5,00% de molibd\u00eanio, o par de formadores de carbonetos sobre o qual o grau \u00e9 constru\u00eddo, juntamente com 4,00% de cromo. Carbono e van\u00e1dio s\u00e3o os dois valores que separam as classes, em 1,05% e 2,50% na classe 1 e em 1,20% e 3,00% na classe 2. A ficha lista cobalto para ambas as classes e enxofre para a classe 1 sem valor, portanto essas linhas s\u00e3o omitidas da tabela em vez de impressas como zero, e o \u00fanico valor de enxofre que a ficha da classe 2 imprime \u00e9 registrado abaixo da tabela em vez de levado para ela. Os dados de composi\u00e7\u00e3o na tabela s\u00e3o apenas para refer\u00eancia geral, os valores reais variam por norma, usina e n\u00famero de corrida, portanto confirme os valores com o certificado de ensaio do material da corrida ou consulte a Aobo Steel.<\/p>\n\n\n\n

A ficha apresenta uma etapa de pr\u00e9-aquecimento sem condi\u00e7\u00e3o de tamanho associada, portanto a etapa n\u00e3o \u00e9 marcada como necess\u00e1ria apenas para se\u00e7\u00f5es maiores. Ambas as classes recebem \u00f3leo ou sal como meio de resfriamento, sem alternativa de ar impressa ao lado.<\/em><\/p>\n\n\n\n

O pr\u00e9-aquecimento \u00e9 de 1500 \u00b0F (815 \u00b0C) em ambas as fichas. As temperaturas de t\u00eampera ficam 25 \u00b0F (10 \u00b0C) distantes, em 2250 \u00b0F (1230 \u00b0C) para a classe 1 e 2225 \u00b0F (1220 \u00b0C) para a classe 2, e a classe mais fortemente ligada \u00e9 aquela que a fonte define um pouco mais baixa, que \u00e9 a dire\u00e7\u00e3o que a oficina toma quando quer o gr\u00e3o mais fino pelo qual essa classe \u00e9 comprada. Ambas as fichas indicam \u00f3leo ou sal como resfriamento, e nenhuma ficha imprime resfriamento ao ar para o grau, portanto a escolha no tanque \u00e9 \u00f3leo contra sal.<\/p>\n\n\n\n

A ficha varia as temperaturas de revenimento em incrementos de 50 \u00b0F de 900 \u00b0F a 1200 \u00b0F e imprime um valor Rockwell C para cada classe em cada linha. A primeira linha \u00e9 a dureza ap\u00f3s a t\u00eampera, antes de qualquer revenimento, e a eleva\u00e7\u00e3o nas duas linhas seguintes \u00e9 o endurecimento secund\u00e1rio.<\/em><\/p>\n\n\n\n

Ambas as classes saem do resfriamento a 65 HRC e ambas as linhas sobem antes de cair, que \u00e9 o endurecimento secund\u00e1rio que segue o primeiro revenimento. A classe 1 sobe a 67 HRC a 950 e 1000 \u00b0F (510 e 540 \u00b0C) e depois cai para 52 HRC a 1200 \u00b0F (650 \u00b0C). A classe 2 sobe a 66 HRC nas mesmas duas linhas e ainda mant\u00e9m 60 HRC a 1200 \u00b0F (650 \u00b0C), que \u00e9 oito pontos acima da classe 1 no topo da faixa. Uma ferramenta que trabalha quente e precisa manter o fio \u00e9 revenida nessa faixa superior, e a diferen\u00e7a entre as duas linhas ali \u00e9 a diferen\u00e7a pr\u00e1tica entre as classes.<\/p>\n\n\n\n
