The steel shot is atomized into pellets and then subjected to a high-temperature water cooling process, which changes the crystal structure of the steel shot and makes the metallographic structure denser, thereby achieving a more wear-resistant and less easily broken effect. The cost increases by a small part, and the durability increases by a large part
Material:

Secondary quenching refers to the phenomenon where there is a large amount of residual austenite in steel with a high concentration of carbon alloy elements (excluding Co and Al) after quenching, which partially decomposes during tempering heating, resulting in a decrease in the stability of residual austenite, and then transforms into martensite during rapid cooling.
Application:

Secondary quenching can give steel high strength, high hardness, and wear resistance, commonly used in high alloy steels such as high-speed steel. When conducting secondary quenching, it is necessary to develop appropriate quenching processes and parameters based on the material and performance requirements of the steel to achieve the best quenching effect.
