\u00a0 \u00a0 \u00a0 O M4 \u00e9 um a\u00e7o r\u00e1pido com elevado teor de carbono e elevado teor de p\u00f3 de vitamina. Tem as vantagens de uma baixa irregularidade do carboneto e de uma elevada tenacidade e \u00e9 propenso a sobreaquecimento. Por conseguinte, a temperatura de t\u00eampera e de aquecimento deve ser rigorosamente controlada e os requisitos de prote\u00e7\u00e3o do tratamento t\u00e9rmico s\u00e3o rigorosos. Devido \u00e0 sua boa dureza e resist\u00eancia ao desgaste, a ferramenta utilizada para fazer materiais de corte dif\u00edceis O a\u00e7o r\u00e1pido M4 tem uma elevada tend\u00eancia para o carboneto, pelo que tem requisitos rigorosos para a prote\u00e7\u00e3o do tratamento t\u00e9rmico e \u00e9 adequado para moldes que suportam vibra\u00e7\u00f5es e cargas de impacto.<\/span><\/p>\n
