Abstract

PURPOSE: To obtain the titled Ni base alloy comprising C, Si, Mn, W, Cr and Zn each in prescribed ratio and further the remainder of Ni, having a high hardness at a high temperature and excellent thermal impact resistance, lead oxide corrosion resistance and capable of pad-welding with oxygen-acetylene flames.
CONSTITUTION: The titled Ni base alloh comprising 1.0W3.5wt% C, 0.1W1.8wt% Si, 0.1W0.9wt% Mn, 5W20wt% W, 20W40wt% Cr, 0.001W0.35wt% Zn and the remainder of Ni and inevitable impurities. The Ni base alloy does not contain Co causing an increase in cost and can be used for casting of course and also for build up welding with oxygen-acetylene flames. Further when the Ni base alloy is used for the preparation of engine valves and valve seats of particular high performance engines, it exhibits a markedly excellent performance.
