Steel Grades



S355J2 is a non-alloy structural steel that is widely used in the construction and engineering industries due to its high yield strength and good toughness. It is part of the S355 steel grade family, which includes S355J0, S355JR, and S355K2. This steel grade is known for its excellent impact resistance and strength, making it ideal for heavy-duty applications.

S355J2 has a minimum yield strength of 355 MPa and a maximum tensile strength of 680-900 MPa, depending on the thickness. This high strength allows it to be used in applications that require structural support, such as bridges, buildings, and infrastructure. It is also used in the manufacturing of heavy machinery and equipment.

The chemical composition of S355J2 includes carbon, manganese, phosphorus, sulfur, and silicon. It has a maximum carbon content of 0.22%, which is lower than S355JR, making it more suitable for applications that require better weldability. It also has a higher manganese content, which improves its hardenability and allows it to be used in applications that require higher strength.
