The atmosphere corrosion resistance of this steel in most environments is substantially better than that of carbon structural steels with or without copper addition. When properly exposed to the atmosphere, this steel is suitable for many applications in the bare (unpainted) condition. Specifications(T*W*L): 6--200mm * 1500--3700mm * 3000--18000mmis available.Charpy V-Notch Impact Test, Drop-Weight Test, Ultrasonic Examination and Maximum Tensile Strength Test are available for the buyer.
