Descripci\u00f3n:<\/strong><\/h3>\n

El Acero Inoxidable Tipo 441<\/strong> es un acero inoxidable ferr\u00edtico que proporciona buena resistencia a altas temperaturas (superior a la de los Tipos 409 y 439) adem\u00e1s de buena resistencia a la corrosi\u00f3n en muchos ambientes de gases de escape (equivalente al Tipo 439 y aceros inoxidables 18 Cr-Cb). Los aceros ferr\u00edticos no son inherentemente fuertes a temperaturas elevadas, pero las adiciones de columbio junto con un recocido de soluci\u00f3n adecuado mejoran notablemente la resistencia a la ruptura por fluencia a largo plazo. El Tipo 441 est\u00e1 doblemente estabilizado con niobio y titanio para proporcionar buena ductilidad en la soldadura y resistencia a la corrosi\u00f3n intergranular en la zona afectada por el calor de la soldadura.<\/p>\n
