What material is 12Cr1MoV steel

What material is 12Cr1MoV steel?
12Cr1MoV steel is a kind of alloy structural steel. 12 means carbon content is 0.12%. Other chemical elements include chromium, molybdenum and vanadium.

Chemical constituents of 12Cr1MoV steel:
C:0.08-0.15, Si:0.17-0.37, Mn:0.40-0.70, Cr:0.90-1.20, V:0.15-0.30, Mo :0.25-0.35.

Mechanical properties of 12Cr1MoV steel:
12Cr1MoV steel mechanical properties: tensile strength: ≥ 490 MPa, yield strength: ≥ 245 MPa, elongation after fracture: ≥ 22%, reduction of area: ≥ 50%, impact energy: ≥ 71J.

Characteristics and applications of 12Cr1MoV steel:
12Cr1MoV steel has high plasticity in the long-term tension, and is generally used after normalizing and high-temperature tempering. 12Cr1MoV steel is used to manufacture superheated steel pipes, radiator tubes and related forgings in high pressure equipment with working temperature not exceeding 570-585℃.
