Abstract

PURPOSE: To improve durability and wear resistance by welding an alloy piece having a high hardness and a high wear-resistance on the axial end part of a valve and quenching said alloy piece after finishing treatment or further processing with nitriding treatment.
CONSTITUTION: With a welded valve consisting of chip a made of SKH 9, and the bevel part and axis part B made of austenite or ferrite heat resisting steel, an alloy piece C which has a high wear-resistance and has a hardness at least above Hv 500 within the range from normal temperature to 300°C and contains composite carbide such as M6C, MC, and M7C3 more than 10% in volume ration is welded at the axis end part in quenching, and after processed with funishing treatment, said welded alloy piece C is quenched and hardened, or further processed with nitriding treatment to improve wear resistance. Thus, durability and wear resistance can be improved
