12Cr1MoV Steel Plate

12Cr1MoV steel plate is a low-alloy heat-resistant steel specified in the Chinese National Standard (GB/T 3077, GB/T 5310). It contains 0.08%~0.15% carbon, 0.9%~1.2% chromium, 0.25%~0.35% molybdenum, and 0.15%~0.30% vanadium. It corresponds to the United States ASTM A335 P12 steel plate and the Japanese JIS G4105 SCMV4 steel plate.

What is 12Cr1MoV steel Plate?

12Cr1MoV steel offers excellent strength and heat resistance, with a tensile strength of ≥490 MPa, yield strength of ≥255 MPa, elongation of ≥20%, reduction of area of ≥45%, and impact energy of ≥39 J. In its normalized and tempered state, the hardness typically ranges from 160–200 HB, while after annealing, it is usually ≤163 HB.

Additionally, 12Cr1MoV steel exhibits good weldability and creep resistance, making it particularly suitable for high-temperature service up to 580 °C. It is widely used in the manufacturing of boiler tubes, high-pressure vessels, steam pipelines, and turbine components. Furthermore, it has significant applications in the power generation and petrochemical industries. Due to its excellent high-temperature strength and stability, 12Cr1MoV steel is especially prominent in the production of superheater tubes, header pipes, and other critical components operating under long-term thermal stress.

Overview

The surface treatment of the steel plate, whether cold or hot-rolled.
12Cr1MoV steel, a low-alloy heat-resistant steel, belongs to the category of alloy structural steel.
After heat treatment, its strength, hardness, and creep resistance are significantly better than plain carbon steels such as Q235.
ZGT Steel supports various hardness customizations and OEM processing services.
Healthy inventories of 12Cr1MoV steel plate are maintained in all ZGT® Steel distribution centers.
Ability to be riveted, bolted or welded, with excellent performance in high-temperature service.

Benefits of S45c Steel Plate

In the hot-rolled or normalized condition, GB 45 steel is considered to have reliable machinability. Due to its low production cost and relatively soft texture, it is easy to manufacture (manual forging, pressing, or machining can all be used), making it especially suitable for tool types and optimal material for tools.

Applications & Industries

12Cr1MoV steel is commonly used for high-temperature components such as superheater tubes, reheater tubes, and high-pressure boiler tubes. It is also applied in steam pipelines, turbine components, and petrochemical processing equipment. In the power generation industry, 12Cr1MoV steel is used for header pipes, collector pipes, and heat exchangers. It is also found in pressure vessels and reactor parts requiring long-term creep resistance. Additionally, 12Cr1MoV steel is widely applied in the energy, petrochemical, and boiler manufacturing industries due to its excellent high-temperature strength and stability.
