Breaking New Grounds with 25CrMo4 Steel Grade: A Material of Choice for High-Performance Applications

The 25CrMo4 steel grade is gaining recognition for its exceptional properties, making it a material of choice for high-performance applications. It belongs to the family of alloy steels, characterized by its excellent strength, toughness, and wear resistance.

The chemical composition of 25CrMo4 steel includes carbon, silicon, manganese, phosphorus, sulfur, chromium, and molybdenum. The carbon content ranges from 0.22% to 0.29%, providing the material with good hardenability and the ability to withstand high stress and impact.

Silicon is present in the range of 0.15% to 0.35%, contributing to the steel’s strength and resistance to oxidation. Manganese, at 0.60% to 0.90%, enhances the hardenability and tensile strength of the steel.

The phosphorus and sulfur content is limited to a maximum of 0.035%. This ensures the steel’s cleanliness and reduces the risk of brittleness during processing or in high-stress conditions.

Chromium, ranging from 0.90% to 1.20%, provides the steel with excellent resistance to corrosion, wear, and high temperatures. The addition of molybdenum (0.15% to 0.30%) further enhances the steel’s strength, toughness, and resistance to fatigue.

In terms of mechanical properties, 25CrMo4 steel exhibits impressive characteristics. It has a minimum tensile strength of 900 MPa, providing the material with the ability to bear high loads. The yield strength is a minimum of 630 MPa, ensuring the steel’s durability and resistance to deformation under stress.

25CrMo4 steel also possesses good ductility, with a minimum elongation of 16%. This makes the material suitable for applications that require flexibility and the ability to withstand dynamic forces.

Furthermore, the steel grade demonstrates excellent impact energy, with a minimum of 34 J at a temperature of -20°C. This attribute ensures the material’s reliability and performance in low-temperature environments, making it suitable for a wide range of demanding applications.

In conclusion, the 25CrMo4 steel grade represents a breakthrough in high-performance materials due to its exceptional mechanical properties and chemical composition. Its remarkable strength, toughness, and resistance to wear and corrosion make it an ideal choice for applications in demanding industries such as automotive, aerospace, and heavy machinery.
