10CrMo910 Steel Grade: The Future of High-Pressure and High-Temperature Applications

The 10CrMo910 steel grade is a high-strength alloy steel specifically designed for high-pressure and high-temperature applications. It is widely used in industries such as power generation, petrochemical, and oil refining, where the equipment operates under extreme conditions.

Mechanical Properties:

– Tensile Strength: The 10CrMo910 steel grade has a minimum tensile strength of 450-600 MPa, which provides excellent overall strength. This high tensile strength allows the material to withstand high pressures without deformation or failure.

– Yield Strength: The minimum yield strength of 10CrMo910 is 280-450 MPa. This property ensures that the material can resist deformation and remain stable under high-pressure conditions.

– Elongation: The steel has a minimum elongation of 20% to 24%, which indicates its ability to withstand stress and undergo deformation without breaking. This property is crucial in preventing brittle fracture under high loads.

– Impact Toughness: 10CrMo910 exhibits good impact toughness even at elevated temperatures, which is essential for withstanding rapid changes in stress or shock under operating conditions.

Chemical Composition:

The chemical composition of 10CrMo910 steel grade is as follows:

– Carbon (C) content: 0.08% – 0.15%
– Silicon (Si) content: 0.15% – 0.35%
– Manganese (Mn) content: 0.40% – 0.70%
– Phosphorus (P) content: 0.015% maximum
– Sulfur (S) content: 0.005% maximum
– Chromium (Cr) content: 2.00% – 2.50%
– Molybdenum (Mo) content: 0.90% – 1.10%

The addition of chromium and molybdenum enhances the steel’s resistance to oxidation, corrosion, and high-temperature creep. These alloying elements also contribute to the material’s superior strength and high-temperature stability.

In conclusion, the 10CrMo910 steel grade offers excellent mechanical properties, including high tensile strength, good yield strength, and impact toughness. Its chemical composition, with the addition of chromium and molybdenum, ensures excellent resistance to high pressures, high temperatures, and corrosive environments. Therefore, it is considered the future of high-pressure and high-temperature applications in various industries.
