1. Introdu\u00e7\u00e3o aos materiais Hastelloy C276<\/span><\/strong>
\nA liga Hastelloy C-276 \u00e9 considerada uma liga universal resistente \u00e0 corros\u00e3o com um teor extremamente baixo de carbono sil\u00edcio. \u00c9 principalmente resistente ao cloro h\u00famido, v\u00e1rios cloretos oxidativos, solu\u00e7\u00f5es de sal de cloreto, \u00e1cido sulf\u00farico e sais oxidativos, e tem boa resist\u00eancia \u00e0 corros\u00e3o em \u00e1cido clor\u00eddrico a baixa e m\u00e9dia temperatura. Por conseguinte, nos \u00faltimos 30 anos, tem sido amplamente utilizado em ambientes corrosivos dif\u00edceis, como a ind\u00fastria qu\u00edmica, a ind\u00fastria petroqu\u00edmica, a dessulfura\u00e7\u00e3o de gases de combust\u00e3o, a produ\u00e7\u00e3o de pasta e papel e a prote\u00e7\u00e3o ambiental, etc.<\/span><\/p>\n

4. Carater\u00edsticas do material Hastelloy C276<\/span><\/strong><\/p>\n

No estado de oxida\u00e7\u00e3o e redu\u00e7\u00e3o, tem uma excelente resist\u00eancia \u00e0 corros\u00e3o na maioria dos meios corrosivos.<\/span><\/p>\n

Excelente resist\u00eancia \u00e0 fissura\u00e7\u00e3o por picadas, fendas e corros\u00e3o sob tens\u00e3o.<\/span><\/p>\n

A estrutura metalogr\u00e1fica da HastelloyC-276: C276 \u00e9 uma estrutura de treli\u00e7a c\u00fabica de face centrada.<\/span><\/p>\n

5. Resist\u00eancia \u00e0 corros\u00e3o em HastelloyC-276<\/span><\/strong>
\nA liga C276 \u00e9 adequada para v\u00e1rias ind\u00fastrias de processos qu\u00edmicos que cont\u00eam meios de oxida\u00e7\u00e3o e redu\u00e7\u00e3o. O teor mais elevado de molibd\u00e9nio e cr\u00f3mio torna a liga resistente \u00e0 corros\u00e3o de i\u00f5es cloreto, e o elemento tungst\u00e9nio melhora ainda mais a sua resist\u00eancia \u00e0 corros\u00e3o. O C276 \u00e9 um dos \u00fanicos materiais que pode resistir \u00e0 corros\u00e3o de solu\u00e7\u00f5es h\u00famidas de cloro, hipoclorito e di\u00f3xido de cloro. A liga tem uma resist\u00eancia \u00e0 corros\u00e3o significativa a concentra\u00e7\u00f5es elevadas de solu\u00e7\u00f5es de sais clorados (como o cloreto de ferro e o cloreto de cobre).<\/span><\/p>\n
