A norma GB\/T 3098.6-2014 especifica as propriedades mec\u00e2nicas de parafusos, porcas e pinos fabricados com a\u00e7os inoxid\u00e1veis \u200b\u200bresistentes \u00e0 corros\u00e3o, quando testados em uma faixa de temperatura ambiente de 10 \u00b0C a 35 \u00b0C. Esta norma aplica-se a elementos de fixa\u00e7\u00e3o com di\u00e2metros nominais de rosca de 5 mm a 100 mm, garantindo desempenho confi\u00e1vel em diversas aplica\u00e7\u00f5es industriais. Ela classifica os a\u00e7os inoxid\u00e1veis \u200b\u200bem grupos austen\u00edticos, martens\u00edticos e ferr\u00edticos, definindo classes de propriedades com base na resist\u00eancia \u00e0 tra\u00e7\u00e3o, limite de escoamento, alongamento e dureza.<\/p>\n

Propriedades Mec\u00e2nicas<\/h2>\n

As propriedades mec\u00e2nicas descritas na norma GB\/T 3098.6-2014 garantem que os fixadores de a\u00e7o inoxid\u00e1vel atendam a requisitos espec\u00edficos de resist\u00eancia e ductilidade. Essas propriedades s\u00e3o cruciais para aplica\u00e7\u00f5es que exigem resist\u00eancia \u00e0 corros\u00e3o combinada com integridade mec\u00e2nica. A tabela abaixo detalha os valores m\u00ednimos de resist\u00eancia \u00e0 tra\u00e7\u00e3o (Rm), limite de escoamento (Rp0,2), alongamento ap\u00f3s a fratura (A) e faixas de dureza para diferentes grupos de a\u00e7o e classes de propriedades.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n

Para atingir as propriedades mec\u00e2nicas especificadas, o material deve ser temperado e revenido a uma temperatura m\u00ednima de 275 \u00b0C.<\/dd>\n
4. H\u00e1 restri\u00e7\u00f5es quanto ao di\u00e2metro da rosca para a\u00e7o ferr\u00edtico de grau F1?<\/dt>\n
Sim, as propriedades para F1 aplicam-se a fixadores com di\u00e2metros nominais de rosca de at\u00e9 24 mm.<\/dd>\n
5. Como a norma aborda a estabiliza\u00e7\u00e3o em a\u00e7os austen\u00edticos como A3 e A5?<\/dt>\n
A estabiliza\u00e7\u00e3o \u00e9 alcan\u00e7ada atrav\u00e9s da adi\u00e7\u00e3o de tit\u00e2nio (\u2265 5\u00d7C% at\u00e9 0,8%) ou ni\u00f3bio\/t\u00e2ntalo (\u2265 10\u00d7C% at\u00e9 1,0%) para prevenir a precipita\u00e7\u00e3o de carbonetos e aumentar a resist\u00eancia \u00e0 corros\u00e3o.<\/dd>\n
6. O teor de molibd\u00eanio pode ser ajustado na classe A2?<\/dt>\n
O molibd\u00eanio pode ser adicionado a crit\u00e9rio do fabricante, mas limites espec\u00edficos devem ser indicados no pedido de compra para aplica\u00e7\u00f5es que exigem controle preciso.<\/dd>\n<\/dl>\n<\/div>","protected":false},"excerpt":{"rendered":"
