About ASTM A-588
ASTM A-588 Gr. A/B Corten steel plate offers all the advantages of ASTM A572-50 but is produced with elevated levels of copper to add corrosion resistance. This weathering grade provides atmospheric corrosion resistance and ultimately longer life in applications where exposure to elements will be a factor. is often used in unpainted applications such as bridges, utility sign/poles and highway structures and guardrails because of the self-repairing, natural oxide patina greatly reduces maintenance.
Properties
Tensile: 70 ksi min (4 inch and under), 67 ksi min (4-5) 63 ksi min (Over 5-8)
Yield: 50 ksi min (4 and under), 46 ksi min (4- 5) 42 ksi min (Over 5-8)
Elongation: 16 percent min in 8 inch 19 percent min in 2 inch (for plates wider than 24 inch)in sheet.
Typical Uses
This steel can be left unpainted making it ideal application including bridges, buildings, and other structures.
