S355J2 h section steel material characteristics
Mechanical properties
Yield strength: ≥355 MPa
Tensile strength: 470~630 MPa
Low-temperature toughness: Impact energy ≥27 J at -20℃ (meets low-temperature working conditions)
Elongation: ≥21%
Processing performance
Supports cutting, welding, bending and other processes, and is not easy to crack after welding;
Hot rolling process ensures cross-section uniformity, and dimensional tolerances meet EN standards.
Weather resistance
Corrosion resistance is better than ordinary carbon steel, suitable for open air or humid environments.
Mechanical property enhancement process
Heat treatment: Refine the grains through normalizing (air cooling) to improve cutting performance; quenching + tempering to improve comprehensive mechanical properties.
Galvanizing process: Some models can be hot-dip galvanized, and the quality of pre-treatment needs to be controlled to avoid residual oxide film.
Application areas
Building structures
HEB100 h-shaped beam: light-duty plant frames, warehouse support beams;
HEB120 h-shaped iron beam: medium-duty plant main beams, partial load-bearing parts of bridges.
Industrial equipment
Bearing seats and mechanical arm brackets in mechanical manufacturing;
Ship structural parts (such as deck reinforcement).
Special environmental scenarios
Cold region projects (relying on the low-temperature toughness of S355J2);
Outdoor steel structures that require long-term weather resistance.
