5.0mm Ni80Cr20 Bar oo loogu talagalay Walxaha Tubularka ee Birta ah ee la dahaadhay

Sharaxaad Gaaban:

NiCr 80 20 waa isku-darka nikkel-chromium oo loo isticmaalo heerkul ilaa 1200°C. Isku-darka u adkaysta kulaylka waxaa lagu dabaqaa jawiga oksaydhka sida nitrogen, ammonia, jawiga aan degganayn ee ka kooban isku-dhafka sulfur iyo sulfur. NiCr 80/20 wuxuu leeyahay astaamo ka sarreeya iska caabbinta kulaylka marka loo eego isku-darka birta-aluminium.
