Alloy 400 (UNS N04400) muaj corrosion kuj zoo heev, tshwj xeeb tshaj yog nyob rau hauv nruab nrab thiab alkaline ntsev.Nws yog ua los ntawm high-strength nickel tooj liab alloy.Vim yog cov ntsiab lus siab nickel, cov hlau no tsis cuam tshuam los ntawm kev ntxhov siab corrosion tawg los ntawm chloride thiab tsis tsim cov kab nrib pleb.Cov hlau kuj tseem muaj cov khoom siv zoo hauv qhov kub thiab txias ntawm qhov kub ntawm qhov kub mus rau 549 ° C.
