A242 atmospheric corrosion resisting steel ,High strength weathering steel
ASTM A242 steel is a high strength low-alloy structural steel ASTM specification with improved atmospheric corrosion resistance.A242 atmospheric corrosion resisting steel widely used in air preheater, economizer, railway carriage, containers production, bridge building , construction and so on
The original A 242 alloy has a yield strength of 50 kilopounds per square inch (340 MPa) and ultimate tensile strength of 70 ksi (480 MPa) for light-medium rolled shapes and plates up to 0.75 inches (19 mm) thick. It has yield strength of 46 ksi (320 MPa) and ultimate strength of 67 ksi (460 MPa) for medium weight rolled shapes and plates from 0.75–1 inch (19–25 mm) thick. The thickest rolled sections and plates – from 1.5–4 in (38–102 mm) thick have yield strength of 42 ksi (290 MPa) and ultimate strength of 63 ksi (430 MPa).
