Weathering steel Overview: wherein: the alloy composition and the weight percent content of weathering steel is: C: 0.12 ~ 0.21, Si: 0.2 ~ 2.0, Mn: 0.7 ~ 2.0, S ≤0.036, P≤0.034, Cu: 0.10 ~ 0.40 , Al <0.2, the balance being Fe and trace impurities. By Cu, Mn, Si, Al and other alloying, and simple adjustment of ordinary low-carbon steel (Q235 steel) content of some elements in Q235 steel production without changing the process conditions, we can produce a good resistance to atmospheric corrosion comprehensive economic weathering steel mechanical properties.
