1.722 Steel

 

1.722Steel Standard: 34CrMo4 steel is an alloy structural steel defined in the European standard EN 10083. The standard specifies the chemical composition, mechanical properties, and application scope of 34CrMo4 steel.

 

Chemical composition: The chemical composition of 1.722steel includes carbon (C) content of 0.30-0.37%, silicon (Si) content of 0.40%, manganese (Mn) content of 0.60-0.90%, phosphorus (P) content no more than 0.025%, sulfur (S) content no more than 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 1.722steel is 980-1180 MPa.

 

Yield strength: The yield strength of 1.722steel is 785-930 MPa.

 

Elongation at break: The elongation at break of 34CrMo4 steel is 14-24%.

 

Application: 1.722steel is widely used in automobile manufacturing, mechanical engineering, and the petroleum and natural gas industries, and is commonly used to manufacture parts such as pipes, cylinders, and bearings that work under high temperature and high pressure conditions.

 

State: Common states of 1.722steel include hot-rolling, forging, heat treatment, and cold drawing.

 

Advantages: 1.722steel has high strength, high wear resistance, good toughness, and weldability, and is suitable for components that work in high temperature and high pressure environments.

 

Disadvantages: 1.722steel may experience deformation and creep under high temperature stress, requiring proper material selection and design.

 

Common forms and comparison of national grades: The most common forms of 1.722steel include round bars, flat bars, square bars, and tubes, etc. National grades corresponding to 1.722steel include Germany's 1.7220, France's 35CD4, the United Kingdom's 708A37, and China's 35CrMo, etc. Although different national standards may have slight differences, chemical composition and mechanical properties are generally similar.

 

Summary: 1.722steel is an alloy structural steel with high strength, high wear resistance, and good toughness, commonly used in automobile manufacturing, mechanical engineering, and the petroleum and natural gas industries. However, deformation and creep may occur under high temperature stress. The common forms of 34CrMo4 steel include round bars, flat bars, square bars, and tubes, etc. National grades corresponding to 34CrMo4 steel include Germany's 1.7220, France's 35CD4, the United Kingdom's 708A37, and China's 35CrMo, etc.
