A588 Gr.B Weathering Steel Plate
ASTM A588 GR.B steel plate is a hot-rolled weathering steel plate whose composition provides excellent resistance to air corrosion. The steel contains copper, chromium, nickel and phosphorus alloys that enhance its corrosion resistance. ASTM A588 Gr.B corten steel material resists component exposure, making it suitable for use in exposed structures and situations prone to corrosion challenges.
