EN 10025 S355K2G4C Steel – High-Tensile, Fine-Grained (As-Rolled + AR)
S355K2G4C is used for folding, section cold forming and cold drawing grade. The high-tensile fine grained steel is applicable for welding constructions of dynamic load up to -20 °C. Compared to S235J2G3C is achievable a considerable saving of material due to the by 120 MPa higher yield point. The steel shows a by 15% higher resistance to mineral wear due to sliding action in comparison to S235J2G4. Mechanical properties have to comply with EURONORM 164 by arrangement. Max. product thickness amounts 20 mm for folding and 8 mm for cold roll forming grades.
