SA283GrC / D steel grade indicated: "SA" indicates the American Standard carbon structural steel; "283": indicates that the steel yield strength of 283 MPa; "Gr": indicates that Green abbreviation; "C / D": indicates that the steel quality level.
SA283GrC and SA283GrD steel characteristics The performance of carbon steel depends mainly on the carbon content. An increase in carbon content increases the strength and NMness of the steel and decreases the plasticity, toughness and weldability. Compared with other steels, carbon steel used in the earliest, low cost, wide range of performance, the largest amount. Suitable for nominal pressure PN ≤ 32.0MPa, temperature -30-425 ℃ water, steam, air, hydrogen, ammonia, nitrogen and petroleum products and other media.
