Weathering steel, best-known under the trademark Weathering Steel A steel and sometimes written without the hyphen as "Weathering steel", is a group of steel alloys which were developed to obviate the need for painting, and form a stable rust-like appearance if exposed to the weather for several years. United States Steel Corporation (USS) holds the registered trademark on the name Weathering Steel A. Although USS sold its discrete plate business to International Steel Group (now Arcelor-Mittal) in 2003, it still sells Weathering Steel A branded material in strip-mill plate and sheet forms.

The original Weathering Steel A received the standard designation ASTM A 242 TYPE-1("Weathering Steel A*") from the ASTM International standards group. Newer ASTM grades are A 588 ("Weathering Steel A*") and A 606 for thin sheet. All alloys are in common production and use.

JIS G 3125:2004: Japanese grade for weather resistant steel plates: Superior atmospheric corrosion resisting rolled steels This Standard specifies the rolled steel having high atmospheric corrosion resistance, to be used for vehicle, building, steel tower and other structure.

IRSM 41-97 Corrosion Resistance steel INDIAN grade for weather resistant steel plates: IRSM 41-97 standard of Indian railways specifically formed for wagon body due to it high resistance to corrosion, Major wagon builder being Rail Coach Factory.
