10CrMo910 Steel Grade: A Versatile Alloy for Pressure Vessel Manufacturing

The 10CrMo910 steel grade is a versatile alloy used in the manufacturing of pressure vessels. It is primarily used in high-temperature and high-pressure applications, such as in power plants and petrochemical plants.

Mechanical properties of 10CrMo910 steel grade include a minimum yield strength of 280 MPa and a minimum tensile strength of 450-600 MPa. The alloy exhibits good creep resistance, allowing it to withstand long-term exposure to high temperatures without significant deformation. This makes it suitable for use in pressure vessels that operate under constant stress and high temperatures.

The chemical composition of 10CrMo910 steel grade typically includes the following elements:

– Carbon (C): 0.08-0.15%
– Silicon (Si): 0.25-0.35%
– Manganese (Mn): 0.40-0.70%
– Phosphorus (P): 0.025% maximum
– Sulfur (S): 0.010% maximum
– Chromium (Cr): 2.00-2.50%
– Molybdenum (Mo): 0.90-1.10%

The addition of chromium and molybdenum improves the high-temperature strength and corrosion resistance of the alloy. These elements also contribute to the formation of a protective oxide layer on the surface of the steel, which helps prevent oxidation and corrosion.

Overall, the 10CrMo910 steel grade is a reliable choice for pressure vessel manufacturing due to its excellent mechanical properties and chemical composition. It offers exceptional strength, good creep resistance, and corrosion resistance in high-temperature environments.
