Corten A equivalent steels have some common features

Corten A steel is ASTM standard atmosphere corrosion resistant steel. There are also other similiar founction ASTM steel such as ASTM A242, ASTM A588, ASTM A606, ASTM A709 and ASTM A847. Corten A equivalent steels are such as SPA-H, B480GNQR, 09CuPCrNi-A, etc.

Those corten A equivalent steels have some common features. The Cu, Cr, Ni, P, Si and Mn are added as alloying elements to corten A equivalent steels. The chemical composition of these steel alloys is specially formulated to allow the early formation of a rust/iron oxide layer that will provide a weather protective coat to the underlying steels.

Corten A equivalent steels are usually in form of steel sheet, steel coil, steel plate, etc. With good corrosion-resistant properties, corten A equivalent steels are commonly used in structures to save weight, add durability and longthen life cycle.

The main corten steel grades of BBN steel are: Corten A, Coretn B; ASTM A588; ASTM A242; EN10025-5 EN10155 S235J0W, S235J2W, S355J0WP, S355J2WP, S355J0W; TBT1979 09CuPCrNi-A, 05CuPCrNi, GBT4171 Q355GNH, Q235NH, Q295NH, Q355NH; JIS G3125 SPA-H, SPA-C; and so on.
