The process indicators of steel processing
Steel cast is a kind of special processing technology of workpieces. And quenching process is one of the important process, so what are the process indicators of steel processing, steel quenching ?
A: quenching medium.the main purpose of steel cast quenching is to fully get martensite structure. When steel quenching cooling rate must greater than the critical cooling rate of steel. Otherwise we are unable to obtain martensitic structure and their corresponding performance.
2: quenching temperature. Quenching temperature mainly depends on the chemical composition of
cast steel as well as the corresponding critical temperature point.
