S355JO+N is a non-alloy structural steel grade defined under EN 10025-2, known for its impressive strength and weldability. Its typical chemical makeup includes carbon (≤0.20%), manganese (≤1.60%), silicon (≤0.55%), phosphorus (≤0.035%), and sulfur (≤0.035%). The “+N” indicates that the steel is provided in a normalized state, enhancing its toughness and grain structure. It boasts a minimum yield strength of 355 MPa and a tensile strength ranging from 470 to 630 MPa. S355JO+N also offers solid impact resistance at 0°C, making it perfect for demanding work environments and structural applications that require enhanced performance.
