Alta condutividade, pequeno coeficiente de expans\u00e3o linear, superplasticidade e propriedades magn\u00e9ticas.<\/p>\nEm compara\u00e7\u00e3o com o a\u00e7o inoxid\u00e1vel austen\u00edtico, a resist\u00eancia do a\u00e7o inoxid\u00e1vel duplex \u00e9 maior, especialmente a resist\u00eancia ao escoamento \u00e9 significativamente melhorada e as propriedades como resist\u00eancia \u00e0 corros\u00e3o por pite, resist\u00eancia \u00e0 corros\u00e3o sob tens\u00e3o e resist\u00eancia \u00e0 fadiga por corros\u00e3o tamb\u00e9m s\u00e3o significativamente melhoradas.<\/p>\n
Desde o nascimento do a\u00e7o de fase dupla nos Estados Unidos na d\u00e9cada de 1940, ele cresceu para a terceira gera\u00e7\u00e3o. Sua principal caracter\u00edstica \u00e9 que o limite de escoamento pode chegar a 400 a 550 MPa, que \u00e9 o dobro do a\u00e7o inoxid\u00e1vel comum, podendo economizar materiais e reduzir os custos de fabrica\u00e7\u00e3o dos equipamentos.<\/p>\n
Em termos de resist\u00eancia \u00e0 corros\u00e3o, especialmente no ambiente m\u00e9dio (como \u00e1gua do mar, alto teor de \u00edons de cloreto), a resist\u00eancia de pite, corros\u00e3o em fendas, corros\u00e3o sob tens\u00e3o e fadiga por corros\u00e3o do a\u00e7o inoxid\u00e1vel duplex \u00e9 melhor do que o a\u00e7o inoxid\u00e1vel austenita comum.<\/p>\n
o tubo duplex 2205<\/a> a partir de fornecedor de acess\u00f3rios de a\u00e7o inoxid\u00e1vel<\/a> kaysuns tem as caracter\u00edsticas dos a\u00e7os inoxid\u00e1veis austen\u00edticos e ferr\u00edticos. Em compara\u00e7\u00e3o com a ferrita, possui maior plasticidade, tenacidade, sem fragilidade \u00e0 temperatura ambiente, resist\u00eancia \u00e0 corros\u00e3o intergranular e soldabilidade, al\u00e9m de manter a fragilidade de 475 \u00b0 C e alta condutividade t\u00e9rmica do a\u00e7o inoxid\u00e1vel ferr\u00edtico, com super plasticidade. Comparado com o a\u00e7o inoxid\u00e1vel austen\u00edtico, possui alta resist\u00eancia e resist\u00eancia \u00e0 corros\u00e3o intergranular e corros\u00e3o sob tens\u00e3o de cloreto.<\/p>\nO a\u00e7o inoxid\u00e1vel duplex tem excelente resist\u00eancia a corros\u00e3o. \u00c9 tamb\u00e9m um a\u00e7o inoxid\u00e1vel duplex de n\u00edquel-n\u00edquel com estrutura de fase dupla austen\u00edtico + ferrita, e o conte\u00fado das duas fases \u00e9 basicamente o mesmo, portanto, possui a\u00e7o inoxid\u00e1vel austen\u00edtico.
