S450J0
1.0590Higher-strength structural steel with 450 MPa yield, 0°C impact. Bridges the gap between S355 and S460 in the EN 10025-2 series. Used for heavily loaded structures, crane components, and building steelwork where S355 is insufficient but normalized fine-grain (EN 10025-3) is not required.
