Application of 12Cr1MoV Steel Plate

12Cr1MoVG is a type of low-alloy heat-resistant steel, which is widely used in high-pressure boilers, steam turbines, power plants, and other industries where high temperature and high pressure are present. It is particularly suitable for the production of large-scale power plant boiler pressure components and other high-temperature and high-pressure equipment, such as superheaters, reheaters, steam pipes, and headers. Its excellent high-temperature strength, oxidation resistance, and creep resistance make it an ideal material for these applications.

Main features of 12Cr1MoV

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.

Application:

  1. Petroleum and petrochemical industry: 12Cr1MoV high-pressure alloy tubes can be used in high-temperature and high-pressure equipment such as cracking furnaces of petroleum refining units, heavy oil hydrogenation units, catalytic cracking units, and naphtha hydrogenation units. Its characteristics of high temperature resistance, pressure resistance and corrosion resistance enable it to withstand the high temperature and high pressure environment in the furnace to ensure the normal operation of the equipment.

 

  1. Chemical industry: 12Cr1MoV high-pressure alloy tubes can be used in high-pressure reactors, separators, heat exchangers, pipelines and other equipment in chemical plants. In the chemical production process, pipelines and equipment that withstand high temperature, high pressure and corrosive media are often required. The use of 12Cr1MoV high pressure alloy pipes can ensure the safe operation and long-term stability of the equipment.

 

  1. Electric power industry: 12Cr1MoV high-pressure alloy pipes can be used in boilers and high-temperature and high-pressure pipes of thermal power stations. The working conditions of boilers in thermal power stations are very harsh, and they need to withstand high-temperature and high-pressure water vapor and combustion gases. 12Cr1MoV high-pressure alloy pipes have good heat resistance and pressure resistance, and are very suitable as materials for boiler pipes.

 

  1. Metallurgical industry: 12Cr1MoV high-pressure alloy pipes can be used in high-temperature and high-pressure equipment in metallurgical equipment, such as steelmaking furnaces, blast furnaces, and converters. In the metallurgical process, it is necessary to use high temperature and high pressure gas and liquid media for refining and processing, and 12Cr1MoV high pressure alloy pipe has good heat resistance and pressure resistance, which can meet the working requirements of metallurgical equipment.

 

  1. Aerospace industry: 12Cr1MoV high-pressure alloy tubes can be used for high-temperature components of aero-engines and spacecraft. Some components in aero-engines and spacecraft work in extremely harsh high-temperature and high-pressure environments, requiring materials with excellent heat resistance and pressure resistance. 12Cr1MoV high pressure alloy tube has excellent high temperature resistance and pressure resistance, so it is widely used in aerospace field.
