Process:
The function of the engine valve is to input air into the engine and discharge the exhaust gas after combustion, which usually includes a valve stem and a valve head. The ends of the valve stems are heat treated as needed to meet strength requirements.
During heat treatment, different methods will be adopted according to the strength requirements, customer requirements, and valve stem size. If the diameter of the valve stem is greater than or equal to 8mm, surface hardening is required; if the diameter of the valve stem is less than 8mm, full hardening is required.
