May 28, 2010 · Corten A is a weather resistant steel created by alloying copper, chromium and nickel. In addition to this, Corten A has added phosphorous which makes the material best suited for gas flue applications and for aesthetic facias The material is not recommended in heavy load bearing applications in this case Corten B or S355J2W should be considered.
According to the Corten A steel chemical composition, corten a steel is made from adding common steel to a small amount of Cu, Cr, P elements and so on, then making some special process. Thus its corrosion resistance is about 3 to 8 times higher than the common steel. Besides, Cu, Ni element makes the steel possessing the properties,such as nipponsteel Steel COR-TENCOR-TEN begins to rust in the same way as ordinary steel. But soon the alloying elements in COR-TEN cause a protective surface layer of ne-textured rust to form, thereby suppressing corrosion rate. Capitalizing on this excellent property, COR-TEN can be used without painting, thereby nullifying the
