A242 Type I Weathering resistant steel
A242 Type1 steel grade is a hot rolled products of structural steels in technical delivery conditions with improved atmospheric corrosion resistance.As the A242 Type I Corten steel reacts with elements in the atmosphere,the material forms a layer of rust over time which in essence protects the steel from corrosion.A242 Type I steel delivery condition can be hot rolled,Cold rolled,AR/CR/N/TMCP/T/QT as the customer request.Products ling Range:Thickness:8--320mm,Width:1500--4020mm,Length: 3000--18000 mm.
