S275J2 is a widely used non-alloy structural steel plate specified in the European standard EN 10025-2. It is known for its good mechanical properties, weldability, and versatility, making it suitable for various structural applications. Below is a detailed overview of its key characteristics, mechanical properties, and typical applications:

Key Characteristics

Standard: EN 10025-2 (European standard for hot-rolled structural steels).

Material Type: Non-alloy structural steel (carbon-manganese steel), with "J2" indicating it is impact-tested at -20°C (providing good low-temperature toughness).

Processing Performance: Excellent weldability (suitable for common welding methods like arc welding, MIG/MAG welding) and machinability (can be cut, bent, or formed into various shapes).

Mechanical Properties

The mechanical properties of S275J2 are defined by EN 10025-2, with key values as follows:

 

Yield Strength: Minimum 275 MPa (for thickness ≤ 16 mm; slightly lower for thicker plates, e.g., 265 MPa for 16–40 mm).

Tensile Strength: 370–530 MPa.

Elongation: Minimum 22% (for thickness ≤ 16 mm), ensuring good ductility for forming.

Impact Toughness: Minimum 27 J at -20°C, making it suitable for low-temperature environments.

 

 

 

 

 

Typical Applications

S275J2 steel plates are widely used in structural engineering and manufacturing due to their balanced strength, toughness, and processability:

 

Construction and Civil Engineering

Building frames, beams, columns, and structural supports in commercial and industrial buildings.

Bridges, viaducts, and pedestrian walkways (for load-bearing components).

Scaffolding, formwork, and temporary structural supports.
