ABSTRACT:
A high-hardness heat-resistant alloy comprising 13-17 wt % of Cr, 2-6 wt % of Al, 0.1-8 wt % of Mo, 1.5-3.5 wt % of B, 0.5-3 wt % of Ti, and 4-7 wt % of Co, the remaining components of the alloy being Ni and inevitable impurities. The alloy has high hardness and high strength at high temperatures and is therefore very suitable for use as a deposit or build-up welding material for exhaust valves in large low-speed diesel engines.
