18crnimnmoa quenching and tempering steel Description

Can quenching reduce the hardness of steel?Can quenching reduce the hardness of steel?Moreover, quenching can reduce the crystal grain size of materials, such as metallic object and plastic materials, to increase the hardness. Further, this process is mainly applied for hardening steel. Usually, cast steel has a uniform, soft crystal grain structure that we call pearlitic grain structure.Difference Between Quenching and Tempering Compare the 18crnimnmoa quenching and tempering steel What is quenched and tempered steel? - ShapeCUT

Quenching and tempering are processes that strengthen and harden materials like steel and other iron-based alloys. The process of quenching or quench hardening involves heating the material and then rapidly cooling it to set the components into place as quickly as possible. What is temperature of quenching?What is temperature of quenching?After quenching, high temperature tempering is called quenching and tempering. Steel is heated to a temperature that is 10-20 degrees higher than that during quenching. After heat preservation, quenching is performed, and then tempered at a temperature of 400-720 degrees.12 Heat Treatment Processes Annealing, Normalizing 18crnimnmoa quenching and tempering steel
