Abstract
The alloys according to the invention are the Co-base alloys which contain C, Si, Cr, W, Mo, Ti and Al, and further, as necessary, contain one, two or more elements among Mn, Ni, Fe, Nb and B, having high thermal shock resistance and lead oxide corrosion resistance. Furthermore the alloys can be used for build-up welding and casting, therefore they demonstrate excellent performance when used in the manufacture of engine valves and valves seats of high performance engines.
