Corten / Weathering Steel Corten / Weathering steel is resistant to atmospheric corrosion steel, is a series of low-alloy steels between ordinary steel and stainless steel. Weathering steel is made of ordinary carbon steel and a small amount of corrosion-resistant elements such as copper and nickel. It has the toughness and plasticity of high-quality steel. Characteristics of elongation, forming, welding, abrasion, high temperature and fatigue resistance; weather resistance is 2 to 8 times that of ordinary carbon steel, and coating performance is 1.5 to 10 times that of ordinary carbon steel .
