Method of hardening valve face of diesel engine

Valve is an important part of diesel engine, and it is an important part that determines the performance and reliability of diesel engine. Failure of valve in use will directly cause damage to engine cylinder, piston, supercharger and other components. In order to improve the wear resistance, fatigue strength and service life of the valve, our company's NIMONIC80A valve adopts the cold extrusion method to improve the hardness, and the working time is doubled.
