EN 10025 Grade S355K2G3 normalized or normalized formed (+N)
EN 10025 Grade S355K2G3 normalized or normalized formed (+N) introduction
S355K2G3 is a high-tensile fine grained steel for welding constructions of dynamic load. The steel is applicated up to temperatures of -20°C. Mechanical properties in thickness direction have to comply with EURONORM 164. Compared to S235J2G3 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 S355K2G3C.
For this steel are available (mat. No 1.0593 acc. to DIN EN 10025) grades for:
- folding (KQ)-S355K2G3C
- cold forming of sections (KP)-S355J2G3C
- cold drawing (KZ)-S355J2G3C.
