    Cov Cim Npe Khoom

    NiCr 70-30 (2.4658) yog siv rau cov khoom siv hluav taws xob uas tiv taus xeb hauv cov cub tawg uas muaj huab cua txo qis. Nickel Chrome 70/30 tiv taus kev oxidation hauv huab cua heev. Tsis pom zoo kom siv rau hauv cov khoom siv cua sov MgO sheathed, lossis cov ntawv thov siv nitrogen lossis carburizing atmospheres.
