Discutiremos as diferen\u00e7as entre os a\u00e7os inoxid\u00e1veis 316 e 316L nesta se\u00e7\u00e3o.<\/p>\n<h3>Resist\u00eancia \u00e0 corros\u00e3o<\/h3>\n<p>O a\u00e7o inoxid\u00e1vel 316L \u00e9 mais resistente \u00e0 corros\u00e3o por \u00e1cidos e cloretos do que o a\u00e7o inoxid\u00e1vel 316. Isso ocorre porque ele cont\u00e9m menos carbono e mais molibd\u00eanio. Por isso, o a\u00e7o inoxid\u00e1vel 316L \u00e9 mais adequado para o seu projeto, pois pode suportar mais \u00e1cidos, produtos qu\u00edmicos e ambientes.<\/p>\n<h3>Baixo teor de carbono<\/h3>\n<p>Em processos de fabrica\u00e7\u00e3o que exigem muita soldagem, o a\u00e7o 316L \u00e9 melhor que o a\u00e7o inoxid\u00e1vel 316 por apresentar menor teor de carbono. Esta \u00e9 a principal diferen\u00e7a entre o a\u00e7o inoxid\u00e1vel 316 e o a\u00e7o inoxid\u00e1vel 316L.

O a\u00e7o 316L tem um teor de carbono menor que o a\u00e7o inoxid\u00e1vel 316. Como resultado, o a\u00e7o inoxid\u00e1vel 316L \u00e9 melhor que o a\u00e7o inoxid\u00e1vel 316 para algumas aplica\u00e7\u00f5es, como onde \u00e9 necess\u00e1ria resist\u00eancia \u00e0 corros\u00e3o.<\/p>\n<h3>Custo<\/h3>\n<p>O pre\u00e7o \u00e9 um fator importante na escolha de qualquer tipo de a\u00e7o.

Portanto, sua escolha deve depender das necessidades do seu trabalho.<\/p>\n<h3>Propriedades magn\u00e9ticas<\/h3>\n<p>O a\u00e7o inoxid\u00e1vel 316 n\u00e3o \u00e9 magn\u00e9tico porque n\u00e3o reage bem a campos magn\u00e9ticos. No entanto, a estrutura s\u00f3lida de alguns a\u00e7os inoxid\u00e1veis 316 pode ser alterada por processamento adicional, como soldagem, para torn\u00e1-los mais magn\u00e9ticos.<\/p>\n<h3>Processo de fabrica\u00e7\u00e3o<\/h3>\n<p>Antes de escolher qual a\u00e7o inoxid\u00e1vel usar para fundi\u00e7\u00e3o de chapas met\u00e1licas ou <a href=\"https:\/\/yonglihaomachinery.com\/pt\/cnc-machining\/\" target=\"_blank\" rel=\"noopener\"><strong>Usinagem CNC<\/strong><\/a>, \u00c9 fundamental compreender as diferen\u00e7as entre o a\u00e7o 316L e o a\u00e7o 316.
