Unveiling the Properties and Applications of 12CrMo10 Steel Grade

12CrMo10 is a low-alloy steel grade that is commonly used in the manufacturing of pressure vessels and piping systems in various industries. It is known for its excellent mechanical properties, durability, and resistance to high temperatures and corrosion.

The chemical composition of 12CrMo10 steel grade typically includes:

– Carbon (C): 0.08% – 0.15%
– Silicon (Si): 0.17% – 0.37%
– Manganese (Mn): 0.40% – 0.70%
– Phosphorus (P): maximum 0.025%
– Sulfur (S): maximum 0.010%
– Chromium (Cr): 1.00% – 1.50%
– Molybdenum (Mo): 0.45% – 0.60%
– Vanadium (V): 0.10% – 0.25%

These alloying elements contribute to the overall strength, heat resistance, and corrosion resistance of the steel grade. The presence of chromium and molybdenum enhances the steel’s ability to withstand high temperatures and pressure, while also improving its resistance to oxidation and corrosion. Additionally, the small amounts of vanadium help to refine the grain structure, improving the toughness and strength of the steel.

The mechanical properties of 12CrMo10 steel grade are as follows:

– Tensile Strength: 450 – 600 MPa
– Yield Strength: 280 – 500 MPa
– Elongation: 20% – 30%
– Reduction in Area: 40% – 50%
– Hardness: 180 – 220 HB
– Impact Toughness: ≥ 27 J/cm2

These properties make 12CrMo10 suitable for various applications in the oil and gas, power generation, chemical processing, and petrochemical industries. It is commonly used in the construction of boilers, pressure vessels, heat exchangers, pipelines, and other high-temperature equipment. The steel grade’s excellent heat and corrosion resistance, combined with its mechanical strength, make it a reliable choice for demanding environments where safety and performance are critical.
