EN 27MnCrB5-2

 

27MnCrB5-2 steel is a type of low-alloy steel. Here is detailed information about 27MnCrB5-2 steel:

Standard: 27MnCrB5-2 steel conforms to the EN 10083-3 standard.

 

Specific chemical composition: The chemical composition of 27MnCrB5-2 steel includes Carbon (C) 0.24-0.30%, Silicon (Si) ≤0.40%, Manganese (Mn) 1.10-1.40%, Phosphorus (P) ≤0.035%, Sulfur (S) ≤0.020%, Chromium (Cr) 0.30-0.60%, Boron (B) 0.0008-0.0050%.

 

Tensile strength: The tensile strength of 27MnCrB5-2 steel is 900-1200 MPa.

 

Yield strength: The yield strength of 27MnCrB5-2 steel is 600-1100 MPa.

 

Fracture elongation: The fracture elongation of the steel is between 7-14%.

 

Applications: 27MnCrB5-2 steel is widely used in the mechanical and construction industries, especially in the manufacturing of high-strength components such as bearings, gears, forgings, and various connectors.

 

State: 27MnCrB5-2 steel is usually supplied in the state of normalized or normalized and tempered, or in a hot-rolled state.

 

Advantages: The steel has excellent heat treatment performance, and good strength and toughness properties can be obtained through heat treatment.

 

Disadvantages: The machining of 27MnCrB5-2 steel is relatively poor, and cracking and other problems may occur during processing.

 

Common forms: The most common forms of 27MnCrB5-2 steel include round bars, square bars, sheets, and tubes.

 

Comparison of national standards: 27MnCrB5-2 steel has different corresponding national standards in different countries, such as W-Nr 1.7182 (Germany), AISI 4130 (USA), and 35CrMo (China).

 

In summary, 27MnCrB5-2 steel is a low-alloy steel widely used in the manufacturing of high-strength components in the mechanical and construction industries. Although it has excellent heat treatment performance and toughness properties, the steel's poor machinability requires appropriate measures during processing.
