карбид хрома порошок (LF-Cr3C2-SX)

Chromium carbideThe product basic situation introduced:Molecular weight:180.02 Carbon content:13.344% Density:6.68 g/cm3 Melting point:1890ºC Boiling point:3800ºC Chromium carbide is gray powder with rhombic system structure,which is undissoluble in water and resistant to acid and alkali.It is high melting-point inorganic material with wear resistance,corrosion resistance and resistance to oxidation at elevated temperature(1000 1100ºC),and is expansively used as thermal spray material to protect the metal surface,and as additive to fine the cemented carbide crystal and some other wear-resistant and corrosion—resistant organ as well.Cr3C2 cermet has excellent resistance to oxidation at high temperature.The cermets surface only will darken in some sort after exposed at 980 ºC for 5 hours.However,18-8 stainless steel destroyed obviously and the WC-6Co alloy oxidized entirely at the same condition. 1.GRADE: Cr3C2 -SX 2.CHEMICAL COMPOSITION(%) Ctotal: 12.7-13.5 Cfree: 0.05-0.3 3.IMPURITY(max): Fe: 0.1 Si: 0.05 Co: 0.02 Nb: 0.01 O: 0.4 N: 0.2 Na: 0.01 K: 0.005 Ca: 0.01 S: 0.03 4.Particle size : 5-400mesh 5.
