ASTM A242 material is a kind of low alloy high strength structural weathering resistance steel, or corten steel, or atmosphere corrosion resistance steel . There is one only grade in A242, that is A242 TYPE 1 steel. ASTM A242 TYPE 1 chemical composition
ASTM A572 - SSABThe ASTM A572 specification is the Standard Specification for High-Strength Low-Alloy Columbium-Vanadium Structural Steel for plates used in general construction and structural applications. ASTM A572 includes five grades with specified minimum yield strengths of 42, 50, 55, 60, and 65 ksi, respectively. For applications where notch toughness is important, consult SSAB for specific Charpy V
ASTM A871-65 is a high strength low-alloy structural steel plate with improved atmospheric corrosion resistance. This specification provides for a 65ksi minimum yield strength and an 80ksi minimum tensile strength plus the atmospheric corrosion resistance of this steel in most environments is substantially better than that of carbon steels with or without copper addition.
