Crushing load is one of stainless steel ball important performance test. It is different based on the steel ball diameter. Many things can affect the crush load of steel balls. Such as, heat treatment, tempering and quenching during heating.
Crushing load of steel balls refers to the pressure value when the balls are forced by the external power. The microstructure of the stainless steel raw material, heat treatment organization status and different process, all these things can change the crushing load of steel balls. Besides, geometric accuracy, surface quality and machining are the indicators to measure crushing load of steel balls. The crushing load can be improved during heat treatment, quenching and tempering, which can change the internal structure of steel balls, and then improve hardness and crushing load.
