12Cr1MoV has higher antioxidant and thermal strength. The creep limit of 12Cr1MoV steel is very close to the rupture strength, and 12Cr1MoV material has high plasticity under the condition of lasting tension. 12Cr1MoV steel has good manufacturability and weldability, but it needs preheating to 300 C before welding. After welding, material 12Cr1MoV needs to remove stress also.
