39MnCrB5-2

 

39MnCrB5-2 steel is an alloy structural steel with high strength and good ductility. Here's detailed information about 39MnCrB5-2 steel:

Standard: 39MnCrB5-2 steel conforms to the EN 10083-3 standard.

 

Specific Chemical Composition: The chemical composition of 39MnCrB5-2 steel includes Carbon (C) 0.36-0.42%, Silicon (Si) 0.40%, Manganese (Mn) 1.15-1.45%, Phosphorus (P) ≤0.025%, Sulfur (S) ≤0.035%, Chromium (Cr) 0.30-0.60%, Boron (B) 0.0008-0.005%.

 

Tensile Strength: The tensile strength of 39MnCrB5-2 steel is between 900-1200 MPa.

 

Yield Strength: The yield strength of 39MnCrB5-2 steel is between 600-1000 MPa.

 

Fracture Elongation: The fracture elongation of the steel is between 10-20%.

 

Applications: 39MnCrB5-2 steel is widely used in the manufacturing of high-strength components in the automotive, machinery, aerospace industries, such as drive shafts, pin shafts, gears, crankshafts, etc.

 

State: 39MnCrB5-2 steel is usually supplied in a quenched and tempered state to adjust its mechanical properties.

 

Advantages: The steel has good ductility and thermal response, excellent mechanical properties can be obtained through heat treatment, and it also has high strength and good wear resistance.

 

Disadvantages: The machining of 39MnCrB5-2 steel is relatively poor and it is prone to cracking. The inclusion of boron makes its welding properties poor, and special attention is required during the welding process.

 

Common Forms: The most common forms of 39MnCrB5-2 steel include round bars, square bars, sheets, and tubes.

 

Comparison of National Standards: 39MnCrB5-2 steel has different corresponding national standards in different countries. In Germany, its standard is W-Nr 1.7189; in the United States, it is usually corresponding to AISI 5150 or SAE 5150 steel; in China, it is similar to 42CrMo steel.

 

In summary, 39MnCrB5-2 steel is an alloy structural steel with high strength and ductility, widely used in the manufacturing of high-strength components. However, due to its poor machining and welding properties, special attention is required in the process control.
