S355J2 material HEA140x133x5.5x8.5 h steel profile
1. Basic parameters and specifications
Cross-section dimensions: height 140mm, width 133mm, waist thickness 5.5mm, flange thickness 8.5mm, meter weight 24.7kg, regular length 12 meters.

Process standard: hot rolling process is adopted, in line with EN10034 tolerance standard, and EN10025-2 material standard is implemented.

Applicable scenarios: widely used in automobile manufacturing, mechanical structure, building steel structure, shipbuilding and other fields, especially suitable for scenarios requiring high strength and low temperature resistance.

2. Material characteristics
Chemical composition: C≤0.22%, Si≤0.55%, Mn≤1.60%, P≤0.025%, S≤0.025%; with good weldability and corrosion resistance, suitable for complex working conditions.

Mechanical properties: yield strength ≥355MPa, tensile strength 450-680MPa, elongation ≥26%; -20℃ low temperature impact energy ≥27J, excellent low temperature resistance, suitable for projects in cold areas.

3. Certification and standards
Implementation standards: European standard EN10025-2 (structural steel), EN10034 (tolerance standard), some products have passed CE certification.

Domestic corresponding material: equivalent to Q345D (normalized state), but the chemical composition and production process are slightly different.
