Abstract

PURPOSE: To provide Ni base alloy for an engine valve and a valve seat of an internal combustion engine with excellent high temperature hardness, heat impact resistance and oxidative lead corrosion resistance comprising a specific component composition of C, Si, Mn, W or the like.
CONSTITUTION: This Ni base alloy comprises C; 1W3.5wt% (and so forth), Si; 0.1W2%, Mn; 0.1W2%, W; 5W20%, Cr; 2W40%, a balance of Ni and inevitable impurities. This alloy is excellent in heat impact resistance and oxidative lead corrosion resistance compared to a conventional Co base alloy and, if 1W30% of Fe is added moreover, heat impact resistance is still more enhanced and, if 2W9% of Mo is added, high temperature hardness is still more enhanced. Above described Fe and Mo may be added together.
