Corten A,the purity of the steel of fine grade austenitic quality and the addition of special alloys Cu, Cr, P elements and so on, provide this steel plates,excellent mechanical characteristics, even at high temperatures and self-passivating properties when exposed to corrosive agents present in urban atmosphere.
Corten A chemical details 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 details of 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 according to ASTM standard which with the yield strength of 355MPa and the tensile strength of 470-630MPa. Besides, its elogation is above 20%. Corten A weather-ability is about 3-8 times of 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.
Corten A enjoys excellent mechanical characteristics at high temperatures and self-passivating properties when exposed to corrosive agents present in urban atmosphere.This mechanical property allows this steel to face down corrosion for longer periods when compared to common steel, even if not painted.
