    • PURPOSE: To obtain a steel for suction and exhaust valves for an internal- combustion engine with high strength for thermal fatigue by manufacturing an Fe-Ni alloy having a specified composition.
      CONSTITUTION: The steel for valves is made of an alloy having a composition consisting of, by weight, ≤0.1% C, ≤0.5% Si, ≤0.5% Mn, 35.0W45.0% Ni, 20.0W 25.0% Cr, 0.5W2.0% Nb, 2.0W3.0% Ti, 1.0W2.0% Al, 0.001W0.01% B and the balance Fe. The steel is characterized by the strength for thermal fatigue kept stably even after holding at a high temp. for a long period. The steel has high strength for thermal fatigue especially at ≥about 800°C, high age hardness after holding for a long period, and high tensile strength at high temp.
