Caracter\u00edsticas de Processamento e Servi\u00e7o dos A\u00e7os para Ferramentas<\/h1>\n\n\n\n

Classifica\u00e7\u00f5es comparativas de resist\u00eancia \u00e0 descarboneta\u00e7\u00e3o, resposta ao endurecimento, distor\u00e7\u00e3o, resist\u00eancia \u00e0 fissura\u00e7\u00e3o, dureza, usinabilidade, tenacidade, resist\u00eancia ao desgaste e resist\u00eancia ao amolecimento para todos os principais graus de a\u00e7o ferramenta.<\/p>\n\n\n\n

As colunas classificadas usam a escala de oito n\u00edveis: M\u00ednimo, Baixo, Baixo a m\u00e9dio, M\u00e9dio, M\u00e9dio a alto, Alto, Muito alto, M\u00e1ximo. Valores mais altos s\u00e3o melhores para resist\u00eancia \u00e0 descarboneta\u00e7\u00e3o, resist\u00eancia \u00e0 fissura\u00e7\u00e3o, usinabilidade, tenacidade, resist\u00eancia ao desgaste e resist\u00eancia ao amolecimento; para quantidade de distor\u00e7\u00e3o, uma classifica\u00e7\u00e3o mais baixa \u00e9 melhor. A resposta ao endurecimento \u00e9 indicada como rasa, m\u00e9dia ou profunda, e a dureza como uma faixa HRC.<\/p>\n\n\n\n
