Microstructure and Properties of Forging Engine Valve Seat
Microstructure and properties of Forging high Cr cast iron were investigated according to the requirements for production and application of engine valve seat. It is found that the microstructure of Forging high Cr cast iron consists of tempering martensite, M7C3 carbide and austenite. The strength ,and plasticity and hardness of Forging high Cr cast iron after heat treating is higher than that of centrifugal casting high Cr cast iron. So the Forging high Cr cast iron can meet the application demand of the engine valve seat.
