A283 Carbon Steel Plate

ASTM A283 is a standard specification for low and intermediate tensile strength carbon steel plates of structural quality for general application. It covers four grades (A, B, C, D) with incrementally higher minimum yield and tensile strength requirements. Q195 is a comparable Chinese standard (GB/T 700) grade, often supplied as an equivalent.
