摘要： Disclosed is a method of manufacturing a diesel engine valve for intake and exhaust having good corrosion resistance and increased valve face strength, and therefore, of improved durability. A Ni-base heat resistant alloy of strong precipitation hardening type or an Fe-base heat resistant alloy of the same type is used as the material. The method comprises hot forging to prepare a blank form of the valve to be manufactured, solution treatment, cold processing to form the face part, and age-treating for increasing the hardness of the face part.
