The seamless carbon steel pipe for ships (gb5213-85) is the seamless carbon steel pipe for the manufacture of class I pressure pipe system, class II pressure pipe system, boiler and Superheater of ships. ASME SA299 Gr A carbon steel boiler plate. The working temperature of carbon steel seamless pipe wall shall not exceed 450 ℃, and that of alloy steel seamless pipe wall shall exceed 450 ℃.
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, ASME SA299 Gr A carbon steel boiler plate 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.
