Weathering steel alloys like Corten A/B were developed for hard-wearing industrial applications to eliminate the need for costly finishing and refinishing. Primary alloying elements in the steel (copper, chromium, and nickel) actively cause atmospheric corrosion at the surface to generate a hard, corrosion-resistant patina. This protective layer actively and continuously regenerates when Corten steel welding of S690QL is subjected to weathering influences, including airborne pollutants, humidity, and rain.
