ASME SA283 Grade D steel

ASTM A283M “Standard Specification for Pressure Vessel Plates, Carbon Steel, Low- and Intermediate-Tensile Strength” is  is under the jurisdiction of ASTM Committee A01 on Steel, Stainless Steel and Related Alloys and is the direct responsibility of Subcommittee A01.02 on Structural Steel for Bridges, Buildings, Rolling Stock and Ships. There are only two grade in the standard ASTM A283M--Grade C and D. Katalor always keeps thousands of steel pressure vessel plates including A283 plates.

ASTM A283GR. D is a kind of carbon steel plates of structural quality for general application. When the steel is to be welded, a welding procedure suitable for the grade of steel and intended use or service is to be utilized. See Appendix X3 of Specification A6/A6M for information on weldability.

In standard ASTM A283M, there are two types including plates of ASTM A283 Grade D and Grade C. As to the Chemical composition, the different content is a main on carbon content, while the carbon content of A283Gr. D is no more than 0.27% and it is higher than Grade C (≤0.24%) ; as to the mechanical property, the differences are tensile strength and yield strength, while the tensile strength of ASTM A283 Gr.D is 415-550MPa (60-80 ksi) and yield strength of ASTM A283 Grade D is 230MPa (33 ksi).
