S275J2 Low Carbon High Strength Steel H Beams
S275J2 carbon steel is a low-carbon, high-strength structural steel specified in the European standard EN 10025, designed for H-shaped steel with strong low-temperature toughness. It is equivalent to Q275D in the Chinese standard (GB/T 700), but the impact toughness requirements are more stringent.
Comparison with Similar Grades
| Grade | Impact Test Temperature | Key Difference |
|---|---|---|
| S275JR | 20°C | General-purpose structural use |
| S275J0 | 0°C | Moderate low-temperature toughness |
| S275J2 | -20°C | Superior cryogenic performance |
Mechanical properties of carbon structural H steel of S275J2
Yield strength: ≥275 MPa
Tensile strength: 430–580 MPa
Elongation: ≥23% (ensures ductility for forming and welding)
Impact toughness: ≥27 J at -20°C, very suitable for low temperature environments
Hardness: Balanced machinability for structural applications.
Production and dimensions
Manufacturing: S275J2 H-beams are produced with optimized grain structure by hot rolling and controlled cooling.
Common H-beam profiles: HEM 1000, with depths up to 1000 mm and flange widths up to 400 mm, widely used in long-span structures. GNEE can customize dimensions for special applications (e.g. bridges, industrial machinery).
Applications of S275J2 low-carbon structural steel
Architecture: Load-bearing beams, columns and frames in buildings and bridges.
Transport: Railway tracks, crane components, and shipbuilding structures.
Industrial equipment: Machinery frames, conveyor systems, and pressure vessels.
