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

Ni70Cr30 yog ib qho austenitic nickel-chromium alloy uas tsim nyog rau kev siv qhov kub thiab txias txog li 1250 ° C. Cov chromium ntau (30% qhov nruab nrab) muab lub neej zoo heev, tshwj xeeb tshaj yog nyob rau hauv cov ntawv thov rau lub cub tawg. Ni70Cr30 yog tus cwj pwm los ntawm kev tiv taus siab, kev tiv taus oxidation zoo, kev ua haujlwm zoo tom qab siv thiab kev vuam zoo heev.

Ni70Cr30 siv rau cov khoom siv hluav taws xob cua sov hauv cov cub tawg kev lag luam. Cov ntawv thov feem ntau yog: cov cub tawg hluav taws xob thiab enamelling, cov cua sov cia khoom, cov cub tawg thiab cov kilns nrog cov huab cua hloov pauv.
