VALVE SEAT MADE OF Fe-Al-C SINTERED ALLOY HAVING SUPERIOR HIGH-TEMPERATURE OXIDATION RESISTANCE AND HIGH STRENGTH

摘要

PROBLEM TO BE SOLVED: To provide a valve seat made of an Fe-Al-C sintered alloy having superior high-temperature oxidation resistance and high strength. SOLUTION: The valve seat is made of the Fe-Al-C sintered alloy having a composition comprising, by mass%, 20-30% Al, 0.5-1.5% C and the balance Fe with unavoidable impurities, and having an Fe-Al-C solid solution single-phase structure.
