12Cr1MoV, alloy structural steel.Standard: GB/ t3077-1999. 12Cr1MoV is a kind of pearlite low alloy heat strength steel, which still has high heat strength and oxidation resistance at 580℃, and has a high durable plasticity. The production process is simple and the welding property is good, but it is sensitive to the normalizing cooling speed. 12Cr1MoV heat resistant steel is used for manufacturing steam parameters 540℃conduit, metal wall temperature less than 580℃ superheater tube and forgings.

 

Main features: compared with 12CrMoV steel, this steel has higher oxidation resistance and thermal strength. The creep limit of the steel is very close to the value of the endurance strength, and it has high plasticity under the condition of the endurance tension. The technology and weldability of the steel are good, but the preheating is required to 300℃ before welding, and the stress is removed after welding.

It is a kind of steel widely used in superheater, header and main steam pipe of high pressure, ultra high pressure, subcritical power station boiler. At 580℃, it still has high thermal strength, oxidation resistance and durable plasticity. The production process is simple and the welding performance is good, but it is sensitive to the normalizing cooling speed. Long-term use at 580℃ will result in the second kind of temper brittleness caused by the segregation of phosphorus and other impurities at grain boundary. Long – term use will also appear pearlite spherification.
