GB 5310 12Cr2MoG Seamless Steel Pipe
12Cr1MoV has higher oxidation resistance and thermal strength. The creep limit of this steel is very close to the durable strength value, and it has high plasticity under sustained stretching; the steel has good processability and weldability, but it needs to be preheated to 300°C before welding, and stress relief is required after welding. deal with. This kind of steel is mainly used after normalizing and high-temperature tempering to manufacture superheated steel pipes, conduits, serpentine pipes and other corresponding forgings in high-pressure equipment whose working temperature does not exceed 570~585℃.
