25CrMo4 Alloy Steel Plate

 

25CrMo4 steel standard: 25CrMo4 steel is a low alloy steel defined in European standard EN 10297-1 and also conforms to EN 10083-3 standard. This standard specifies the chemical composition, mechanical properties, and application scope of 25CrMo4 steel.

 

Specific chemical composition: The chemical composition of 25CrMo4 steel includes a carbon (C) content of 0.22-0.29%, silicon (Si) content of 0.40%, manganese (Mn) content of 0.60-0.90%, a phosphorus (P) content not exceeding 0.035%, a sulfur (S) content not exceeding 0.035%, a chromium (Cr) content of 0.90-1.20%, a molybdenum (Mo) content of 0.15– 0.30%, and iron (Fe) as its main residual element.

 

Tensile strength: The tensile strength of 25CrMo4 steel is 900-1100 MPa.

 

Yield strength: The yield strength of 25CrMo4 steel is 660-900 MPa.

 

Elongation at break: The elongation at break of 25CrMo4 steel is 12-20%.

 

Uses: 25CrMo4 steel is widely used in the manufacture of high-strength mechanical parts, such as engine crankshafts, gears, reducers, connecting rods, and so on.

 

Status: Common states of 25CrMo4 steel include quenched and tempered, annealed, and heat-treated.

 

Advantages: 25CrMo4 steel has good welding performance and high-temperature strength, and is suitable for high-temperature working environments. In addition, the steel has good plasticity and workability.

 

Disadvantages: 25CrMo4 steel is difficult to process and can easily result in serious cutting tool damage and surface cracks. In addition, it is prone to creep at high temperatures.

 

Most common forms: The most common forms of 25CrMo4 steel include round steel, flat steel, square steel, and tubing.

 

Comparison of national grades: The comparison of national grades for 25CrMo4 steel is relatively simple. The British grade is 708A25, the American grade is 4130, and the Chinese grade is 30CrMo.

 

Summary: 25CrMo4 steel is a low alloy steel with high strength, good welding performance, and high-temperature strength, and is widely used in the manufacture of high-strength mechanical parts. The most common forms include round steel, flat steel, square steel, and tubing. The comparison of national grades is relatively simple, such as 708A25 in Britain, 4130 in America, and 30CrMo in China.
