33MnCrB5-2 Boron Steel

 

33MnCrB5-2 steel is an alloy structural steel. Here are the detailed information about 33MnCrB5-2 steel:

Standard: 33MnCrB5-2 steel conforms to the EN 10083-3 standard.

 

Specific chemical composition: The chemical composition of 33MnCrB5-2 steel includes Carbon (C) 0.30-0.37%, Silicon (Si) ≤0.40%, Manganese (Mn) 1.15-1.50%, Phosphorus (P) ≤0.025%, Sulfur (S) ≤0.035%, Chromium (Cr) 0.30-0.60%, Boron (B) 0.0008-0.0050%.

 

Tensile strength: The tensile strength of 33MnCrB5-2 steel is 800-1000 MPa.

 

Yield strength: The yield strength of 33MnCrB5-2 steel is 600 MPa.

 

Fracture elongation: The fracture elongation of the steel is between 10-14%.

 

Applications: 33MnCrB5-2 steel is widely used in the automotive, mechanical, and construction industries, especially in the manufacturing of high-strength components such as transmission shafts, gears, bolts, etc.

 

State: 33MnCrB5-2 steel is usually supplied in a quenched and tempered state.

 

Advantages: The steel has good ductility and responds well to heat treatment, providing high strength and wear resistance.

 

Disadvantages: The machining of 33MnCrB5-2 steel is relatively poor and can be prone to cracking.

 

Common forms: The most common forms of 33MnCrB5-2 steel include round bars, square bars, sheets, and tubes.

 

Comparison of national standards: 33MnCrB5-2 steel has different corresponding national standards in different countries. In Germany, its standard is W-Nr 1.7185; in the United States, it is often compared to SAE 5140 steel; in China, it is similar to 38CrMoAl steel.

 

In summary, 33MnCrB5-2 steel is an alloy structural steel with high strength and ductility, widely used in the manufacturing of high-strength components. However, special attention is required for its poor machinability, and proper process control is necessary.
