SAITRON HF 663 is a highly alloyed with C-Cr-Mo-V hardfacing electrode. Special alloy addition gives microstructure of primary chromium carbide and complex carbide of Mo and V, so that the weld deposit can sustain severe abrasion and erosion resistance even at high temperature upto 600 deg C. It can also be used on equipments operating in corrosive environments. Smooth and stable arc. Very High recovery with less slag.
