ASTM Corten A steel grade is a hot rolled products of structural steels in technical delivery conditions with improved atmospheric corrosion resistance. It owns unique chemical composition and mechanical property, thus enjoys atmospheric corrosion.
Corten A chemical composition mainly contains C (max 0.12%),Si (0.25-0.75%),Mn (0.2-0.5%),P(0.07-0.15%),S(max 0.03%),Cr(0.3-1.25%).Ni (max 0.65%),Cu(0.25-0.55%).
According to the chemical composition , Corten A 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 tenacity, ductility,shaping,welding,cutting,abrasion,fatigue resistance.
For corten A mechanical property, Corten A is made according to ASTM standard which with the yield strength of 355MPa and the tensile strength of 470-630MPa. Corten A weather-ability is about 3-8 times better than common steel, and painting property is 1.5-10 higher than common steel. Besides, corten A can be use under reduction,exposure or simplified painted.
