S355JR is a non-alloy structural steel that boasts impressive mechanical performance and excellent weldability. Its chemical makeup includes carbon (up to 0.24%), manganese (up to 1.6%), along with controlled amounts of silicon, phosphorus, and sulfur. This grade achieves a minimum yield strength of 355 MPa and a tensile strength that ranges from 470 to 630 MPa. It is typically supplied in a normalized or controlled rolled state, ensuring good toughness, particularly in low-temperature conditions. S355JR also meets EN 10025-2 standards, making it a great fit for general structural applications where strength, formability, and impact resistance are key.
