Astm Q235 Corten Steel Plate Certificate Iso 9001 Corten Steel
The alloy composition and weight percentage content of weathering steel are: C: ≤ 0.12, Si: 0.25 ~ 0.75, Mn: 0.2 ~ 0.5, S ≤ 0.02, P: 0.06 ~ 0.12, Cu: 0.25 ~ 0.5, Cr: 0.3 ~ 1.25, Ni: 0.12 ~ 0.65, the rest are Fe and trace elements. By alloying Cu, Mn, Si, Al, etc., and simply adjusting the content of some elements of ordinary low carbon steel (Q235 steel), it is possible to produce economic weathering steel with good atmospheric corrosion resistance and comprehensive mechanical properties without changing the production process conditions of Q235 steel.
