12Cr1MoV is a low-alloy heat-resistant steel bar with excellent high-temperature creep resistance and thermal stability (maintaining reliable performance up to 580°C). It is widely used in the power industry for manufacturing high-temperature and high-pressure boiler components such as superheater header supports, steam pipeline connectors, and boiler drum fasteners, as its heat resistance ensures long-term stable operation under extreme thermal conditions. In the chemical and petrochemical sectors, it is applied to produce reaction vessel stirrer shafts, high-temperature pump rotors, and pressure vessel flanges, benefiting from good corrosion resistance to mild industrial media and high-temperature strength. It also finds use in the metallurgical industry (for annealing furnace structural rods) and thermal power plant auxiliary systems (for high-temperature valve stems), serving as a critical material for industrial scenarios requiring both heat resistance and mechanical stability.
