10CrMo910 Steel Grade: Exploring its Composition and Uses

10CrMo910 is a steel grade that belongs to the EN 10028 standard, which specifies the requirements for flat products for pressure purposes. This steel grade is primarily used in the manufacturing of boilers, pressure vessels, and piping that are subjected to high temperatures and pressure.

The chemical composition of 10CrMo910 steel is as follows:
– Carbon (C): 0.08-0.15%
– Silicon (Si): 0.50% max
– Manganese (Mn): 0.40-1.00%
– Phosphorus (P): 0.035% max
– Sulfur (S): 0.030% max
– Chromium (Cr): 2.00-2.50%
– Molybdenum (Mo): 0.90-1.10%

In terms of its mechanical properties, 10CrMo910 offers high tensile strength, yield strength, and elevated temperature properties. The typical values for these properties are as follows:
– Tensile strength: 450-600 MPa
– Yield strength: 280 MPa min
– Elongation: 18% min
– Impact energy: 27J min at -20°C

The composition and mechanical properties of 10CrMo910 steel make it suitable for applications where high temperature resistance and pressure resistance are required. It is commonly used in power plants, petrochemical plants, refineries, and other industries that involve high temperature and pressure environments.

Furthermore, due to its excellent heat resistance and creep resistance, 10CrMo910 steel can also be used in applications such as steam pipelines, superheaters, heat exchangers, and reactor vessels. Its high tensile strength and toughness ensure the stability and reliability of the structures in these applications even under challenging operating conditions.

Overall, 10CrMo910 steel grade offers a good combination of mechanical properties, chemical composition, and high-temperature resistance, making it a suitable choice for various industrial applications that require strength and reliability in high-temperature and high-pressure environments.
