The iron oxide defects on the surface of 1.8928 material

The secondary quenching and low temperature tempering of wear resistant composite plate are mainly used for high alloy steel workpieces without mechanical processing after carburizing. Carburizing, high-temperature tempering, one-time heating quenching, low-temperature tempering, quenching temperature 840-860℃, mainly used for Cr Ni alloy carburizing workpiece. The second quenching and low-temperature tempering of wear-resistant composite plate, 1.8928 material mainly improves the microstructure of the infiltrated layer. When the requirements for core properties are not high, quenching can be performed between AC1 and AC3, and when the requirements for core properties are high, it should be quenched above AC3.
