12CrMoVA is a low alloy chromium molybdenum vanadium steel
12CrMoVA has high high temperature strength and heat resistance, and can maintain good mechanical properties at high temperatures.
12CrMoVA has good toughness and impact toughness, and has good crack resistance under impact load.
12CrMoVA has good antioxidant properties and can resist oxidation and corrosion under high temperature conditions.
use:
Petrochemical equipment: 12CrMoVA is commonly used in the manufacture of petrochemical equipment, such as refinery furnaces, reactors, storage tanks, etc., and has good durability in high temperature, high pressure and corrosive environments.
Boilers and pressure vessels: Due to its good high-temperature strength and pressure resistance, 12CrMoVA can be used to manufacture boilers, pressure vessels, pipes and other equipment that need to withstand high temperatures and pressures.
Pipeline engineering: 12CrMoVA can be used in petroleum, natural gas and chemical pipeline engineering to meet the transportation requirements under high pressure and high temperature conditions.
Heat treatment:
1. Solution treatment: Heat 12CrMoVA to 950°C-1050°C, keep it warm for a period of time and then cool quickly to improve its hardness and strength.
2. Normalizing treatment: After solution treatment, 12CrMoVA is heated to 680°C-720°C and kept for a period of time, and then quickly cooled by water cooling or oil cooling. This results in the right combination of strength and toughness.
3. Quenching and tempering treatment: 12CrMoVA after solution treatment can be quenched and tempered to further improve its hardness and strength, and adjust its mechanical properties and organizational structure.
