JIS G3114 hot-rolled plate grade SMA490BW cold bending

The location weld of JIS G3114 hot-rolled plate grade SMA490BW, wear-resistant steel plate is only allowed to be welded on the base metal surface with the electric welding rod for welding the base metal; in the welding of the base course, the base weld shall be strictly prevented from melting to the transition layer or even the multiple layer weld of stainless steel, so as to prevent a small amount of high chromium and high nickel surfacing wear-resistant steel plate components diluted into the carbon steel weld to form martensite structure and harden.

Weathering steel is characterized in that the alloy composition and weight percentage content. The chemical composition C≤0.12, Si: 0.25 ～ 0.75, Mn: 0.20 ～ 0.50, P: 0.07 ～ 0.15, S≤0.03, Cu: 0.25 ～ 0.55 , Cr: 0.30 ～ 1.25, Ni≤0.65, and the rest are Fe and trace impurities. Weathering steel sheet JIS G3114 hot-rolled plate grade SMA490BW is mainly used for steel structures such as railways, vehicles, bridges, and towers that are exposed to the atmosphere for a long time.
