Application Environment and Parameters of 12MnNiVR Steel Plate

12MnNiVR is a low-alloy high-strength steel plate, particularly suitable for manufacturing equipment that withstands high pressure and high temperatures. "12Mn" indicates that the steel plate contains approximately 1.2% manganese (Mn), "Ni" represents the presence of nickel (Ni), "V" refers to vanadium (V), and "R" typically denotes that this steel plate has undergone normalizing treatment to optimize its microstructure and enhance impact toughness.

The addition of manganese and nickel improves the strength and toughness of the steel plate, while vanadium, as a trace alloying element, further enhances the strength and wear resistance of the steel by forming hard phases such as vanadium carbide. Normalizing treatment helps eliminate internal stresses, refine grain structure, and endow the steel plate with excellent overall mechanical properties.

12MnNiVR steel plate is widely used in industries such as petroleum, chemical, power station boilers, and pressure vessels. It is especially suitable for manufacturing equipment components that need to withstand high pressure and temperature, such as reactors, heat exchangers, and boiler shells. Its good weldability and machinability make it an important material choice in these application fields.
