25CrMoS4 Steel

 

25CrMoS4 steel standard: 25CrMoS4 steel is an alloy structural steel defined in the European standard EN 10083-3. This standard specifies the chemical composition, mechanical properties, and application scope of 25CrMoS4 steel.

 

Specific chemical composition: The chemical composition of 25CrMoS4 steel includes carbon (C) content of 0.22-0.29%, silicon (Si) content of 0.40%, manganese (Mn) content of 0.50-0.80%, phosphorus (P) content not exceeding 0.025%, sulfur (S) content not exceeding 0.035%, chromium (Cr) content of 0.90-1.20%, molybdenum (Mo) content of 0.15-0.30%, and iron (Fe) as the main residual element.

 

Tensile strength: The tensile strength of 25CrMoS4 steel is 800-950 MPa.

 

Yield strength: The yield strength of 25CrMoS4 steel is 590-690 MPa.

 

Elongation at break: The elongation at break of 25CrMoS4 steel is 8-15%.

 

Application: 25CrMoS4 steel is widely used in the manufacturing of components subjected to high temperature and high pressure requirements, such as automotive engines, cylinders, pistons, and sealing rings.

 

Status: The common forms of 25CrMoS4 steel include heat treatment, normalizing, and annealing.

 

Advantages: 25CrMoS4 steel has good hardenability and quenching brittleness, making it suitable for manufacturing high-strength and wear-resistant components.

 

Disadvantages: 25CrMoS4 steel is prone to oxidation and stress corrosion cracking at high temperatures, requiring appropriate protective measures.

 

Most common forms: The most common forms of 25CrMoS4 steel include round bars, flat bars, square bars, and tubes.

 

Comparison of international grades: The comparison of different national grades for 25CrMoS4 steel is complex. Internationally, different countries from Germany to China may use different grades, such as 1.7213 in Germany, 25CD4S in France, and 25CrMo4S4 in the UK. However, the chemical composition and mechanical properties of these grades are generally similar.

 

Summary: 25CrMoS4 steel is an alloy structural steel with good hardenability and quenching brittleness, widely used in the manufacturing of components in high-temperature and high-pressure environments. Common forms include round bars, flat bars, square bars, and tubes. Different countries may have different grade designations, but the chemical composition and mechanical properties are generally similar.
