12Cr1MoV steel plate is widely used in Superheater, header and main steam pipe of high pressure, ultra-high pressure and subcritical power station boiler. At 580 ℃, 12Cr1MoV steel plate still has high thermal strength, oxidation resistance and high durability. The production process of 12Cr1MoV steel plate is simple, the welding performance is good, but it is sensitive to the normal cooling speed.
12Cr1MoV steel plate has high oxidation resistance and thermal strength. The creep limit of 12Cr1MoV steel plate is very close to the value of endurance strength, and it has high plasticity under continuous tension. 12 cr1mov steel technology has good weldability, but before welding, it needs to be preheated to 300 ℃, and after welding, besides stress, it also needs to be treated.
