S275JR S355JR SS400 Carbon Steel Channel
SS400 carbon steel channel is a widely used material for construction and mechanical structures.
[Compared Material]: Equivalent to China's national standard Q235B.
However, its strength is slightly higher than Q235 (SS400 has a tensile strength of 400-510 MPa, while Q235 has a tensile strength of 375-500 MPa).
[Chemical Composition]: Carbon content ≤ 0.22% (mild steel), sulfur and phosphorus contents ≤ 0.050%, and manganese content 1.40%-1.75%.
[Chemical Composition] Features: Moderate strength, excellent weldability, and suitable for cold working (such as cutting and bending).
