ASTM A242 Introduction
ASTM A242 is hot rolled products of structural steels in technical delivery conditions with improved atmospheric corrosion resistance. It was first used in buildings in 1958 because it has anti-corrosion properties, and was widely used for bridges, trains, cars, trucks, container, harbor construction, oil platforms and industrial facilities and so on. It is a copper chromium alloy steel – this alloy displays a greater level of resistance to atmospheric weathering when compared to other unalloyed steels. Its chemical composition promotes the early formation of an adhering protective layer of rust when exposed to the elements.
Common Grade: ASTM standard Corten A, Corten B; GB standard 09CuPCrNi-A/B; JIS standard SPA-H; and others GB standard Q235NH, B460NH
