Abstract
A valve-seat material ideal for valve seats for vehicle-engine exhaust valves with no cobalt contained therein, superior in general use, has superior wear-resistance in high-temperature oxidizing atmosphere, and can be used independently of types of fuel to be used in the non-lead gasoline, lead-contained gasoline, L.P.G. or the like. The recession amount of the valve is extremely decreased and the wear resistance is remarkably improved.
