Resistance to atmospheric corrosion protective rust layer, Weathering steel can be used in low alloy structural steel and other steel structure, such as the manufacture of the vehicle, bridge, tower, container. Compared with general carbon steel, weathering steel has better corrosion resistance in the atmosphere. Compared with stainless steel, weathering steel only tiny amounts of alloy elements, such as phosphorus, copper, chromium, nickel, molybdenum, niobium, vanadium, titanium, alloy element volume accounts for only a few percent, and not as stainless steel, meet the teens, so the price is relatively cheap.http://www.jingyesteel.com.cn/
