What is SMA490AW？

SMA490AW is a type of low alloy steel that is designed to resist atmospheric corrosion. It is often used in structural applications such as bridges and buildings, as well as in railway vehicles and other industrial equipment.JIS SMA 490 AW corten steel plate applicaiton, widely used in air preheater, economizer, railway carriage, containers production, bridge building,construction and so on.
JIS SMA 490 AW corten steel plate resists the corrosive effects of rain, snow, ice, fog, and other meteorological conditions. The surface of the metal SMA490AW can form a coating of dark brown oxidation which inhibits deeper penetration, so SMA490AW steel saves the cost of need for painting and costly rust-prevention maintenance over the years.
SMA490AW steel delivery condition can be hot rolled, Cold rolled ,AR/CR/N/TMCP/T/QT as the customer request.
