What is 12Cr1MoV steel
12Cr1MoV is an alloy structural steel, which implements the GB/T3077-1999 standard, and the unified number code is A31132. The 12Cr1MoV grade is expressed in sequence by the average carbon content and the chemical symbols of the alloying elements. It is read as twelve chromium-molybdenum vanadium. Compared with 12CrMoV alloy pipe, 12Cr1MoV steel has higher oxidation resistance and thermal strength.
Chemical composition:

12Cr1MoV steel plate application
12Cr1MoV steel is mainly used after normalizing and high-temperature tempering to manufacture superheated steel pipes, conduits, serpentine pipes and other corresponding forgings whose working temperature does not exceed 570-585°C in high-pressure equipment.
