Industrial indicators of quenched castings
Steel casting is a kind of workpiece processed by special processing technology. The quenching process is an important process in the processing of steel castings. Then, what are the process indicators of quenching steel castings?
1: Quenching medium. The purpose of quenching of steel castings is to obtain a complete martensitic structure. The cooling rate during quenching of steel castings must be greater than the critical cooling rate of steel castings. Otherwise, the martensitic structure and its corresponding properties cannot be obtained.
Two: Quenching temperature. The quenching temperature mainly depends on the chemical composition of the cast steel and the corresponding critical temperature point.
