Hoobkas Nichrome Alloy Sawb ntawmNi80Cr20Ni70Cr30 Ni60Cr15 Ni35Cr20 Siv hauv cov khoom siv hauv tsev

Ni70Cr30 yog ib qho austenitic nickel-chromium alloy haum rau kev siv kub txog li 1250 ° C. Cov ntsiab lus chromium siab (30% nyob rau hauv nruab nrab) muab lub neej zoo heev, tshwj xeeb tshaj yog nyob rau hauv cov ntawv thov cub. Ni70Cr30 yog tus cwj pwm los ntawm kev ua haujlwm siab, zoo oxidation tsis kam, zoo ductility tom qab siv thiab zoo weldability.

Ni70Cr30 yog siv rau hluav taws xob cua sov ntsiab nyob rau hauv industrial furnaces. Cov ntawv thov yog: hluav taws xob thiab enamelling rauv, cia cov cua sov, cov cub tawg thiab cov kiln nrog cov cua hloov pauv.
