Steel Grades



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

S355K2 has a minimum yield strength of 355 MPa and a maximum tensile strength of 490-630 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 S355K2 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.

S355K2 is often used in the production of steel plates, bars, and sections, as well as in the manufacturing of welded steel pipes. At our company, we produce high-quality seamless steel pipes made from S355K2 and other steel grades.
