High-strength low-alloy steel A242 weather steel plate is an American standard specified in ASTM A242, sometimes known as weathering steel(Corten Steel). This standard is applicable to high strength low alloy structural steels, plates and bars for welding, riveting and bolting structures. These steels are mainly used as components to reduce weight or extend service life. The atmospheric corrosion resistance of this kind of steel is obviously better than that of carbon structural steel with or without copper exposure to the weather, has been wieldy used in the construction of bridges and buildings.
