Carbon steel plate ASTM A283GrA,B,C,D

ASTM A283 Grade A,B,C,D/ASME SA283 Grade A,B,C,D carbon structural steel is steel construction material, a profile, formed with a specific shape or cross section and certain standards of chemical composition and mechanical properties. Structural steel shape, size, composition, strength, storage, etcs235j2 steel grade is a hot rolled products of structural steels in technical delivery conditions with improved atmospheric corrosion resistance.It is equal to UNI standard Fe360DK1 at the competitive price and rapid delivery time.

ASTM A238 Grade A,B,C,D/ASME SA283 Grade A,B,C,D carbon structural steel is steel construction material, a profile, formed with a specific shape or cross section and certain standards of chemical composition and mechanical properties. Structural steel shape, size, composition, strength, storage, etc., is regulated in most industrialized countries.And this specification covers carbon structural steel shapes, plates, and bars of structural quality for use in riveted, bolted, or welded construction of bridges and buildings, and for general structural purposes. Heat analysis shall be used to determine the required chemical composition for carbon, manganese, phosphorus, sulfur, silicon, and copper. Tensile strength, yield strength, and elongation shall be evaluated using tension test and must conform to the required tensile properties.
