S275JR Steel

S275JR steel is a common structural steel, whose execution standard is European standard EN 10025-2. The chemical composition range of this steel grade includes carbon (C) maximum 0.21%, manganese (Mn) maximum 1.50%, silicon (Si) maximum 0.60%, phosphorus (P) maximum 0.045%, and sulfur (S) maximum 0.040%.

The tensile strength of S275JR steel ranges from 410 to 560 MPa, with a minimum yield strength of 275 MPa, and a required fracture elongation of above 20%.

This steel material is mainly used in the fields of construction, bridges, and mechanical manufacturing. Common states include hot rolling, cold drawing, and annealing.

The advantages of S275JR steel lie in its relatively high strength, reliable toughness, and good processability. However, its disadvantages are relatively high cost and unsuitability for use in high-temperature environments.

The most common forms of this steel material include steel plates, steel pipes, and steel bars. In different countries, there are corresponding different grades. For example, in China, Q235B steel can be used as a substitute for S275JR steel, while in the United States, A36 steel can be used as an alternative to S275JR steel.

In summary, S275JR steel is a common structural steel material, mainly used in the fields of construction, bridges, and mechanical manufacturing. It has relatively high strength, reliable toughness, and good processability, with common forms including steel plates, steel pipes, and steel bars. Different countries have corresponding different grades, but the chemical composition and mechanical properties are generally similar.
