Corten steel alloy falls into the category of those that were developed to reduce or eliminate the use of coats, primers or paints on the material to make it rustproof. When exposed to the environment, corten steel forms an outer rust layer that protects this steel from corrosion. This is the reason why corten steel is also called weathering steel.
JIS G3114,JIS G3114 Corten steel,JIS G3114 SMA490CP JIS G3114 SMA490CP Corten steel, SMA490CP Weathering steel, SMA490CP Weathering resistant steel, SMA490CP atmosphere corrosion resistance steel. JIS G3114 SMA490CP Corten steel widely used in air preheater, economizer, railway carriage, containers production, bridge building , construction and so on. SMA490CP chemical composition
SMA490CP steel plate under JIS G3114 standard,it is a kind of weathering steel created by alloying copper, chromium and nickel. SMA490CP steel add phosphorus which makes the material best suited for gas flue applications and for aesthetic facial.
