What are the factors that affect high product parts?
2024-08-21
In the process of tempering high-quality product parts, the stress generated during quenching can be to a certain extent, the decomposition and transformation of martensite and residual austenite metastable structure after quenching, and the temperature of product tempering is usually below the eutectic transition temperature, which is about 650 °C, and the holding time is not less than 2h. The
