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

S355JR has a minimum yield strength of 355 MPa, which is similar to other S355 steel grades. 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 S355JR includes carbon, manganese, phosphorus, sulfur, and silicon. It has a maximum carbon content of 0.24%, which is slightly higher than S355J0 and S355J2. This results in a steel grade that is more suitable for applications that require higher strength and hardness.
