ASTM A588 GR.A/B Corten Steel Sheets and Plates are copper, chromium, nickel, and phosphorus alloy steels, which are used to increase corrosion resistance and strength. The standard composition contains about 0.19% carbon, 0.75–1.35% manganese, and a maximum of 0.25% copper. These grades provide a minimum yield point of 50 ksi (345 MPa) and tensile strength of 70 ksi (485 MPa). When exposed to air elements, the steel develops a stable oxide layer that shields against additional corrosion, limiting the necessity of other coatings and extending its lifespan in extreme weather conditions.

ASTM A588 GR.A/B Weathering Steel Plates and Sheets are also extensively used in applications where both strength and atmospheric corrosion resistance are desired. The weathering steels are suitable for structural uses like building facades, bridges, railway vehicles, shipping vessels, and architectural sculptures. They are also widely found in outdoor furniture, industrial stacks, and public works exposed to climatic conditions. The self-protecting rust-like finish negates the need for painting and provides a distinctive look, making Corten steel a favorite for contemporary architecture. Luke Steel offers project-specific Corten steel solutions based on functional and design requirements.
