ASTM A283/A283M steel standard contains steel grades A283 Grade A, A283 Grade B, A283 Grade C and A283 Grade D. The minimum yield strength of A283GrA carbon steel plate is greater than 165 MPa, and the tensile strength is in the range of 310-415 MPa at rolling indoors. Temperature. Compared with the other three grades of A283 steel, A283 A grade has the lowest limited carbon content, and A283 D grade has the highest carbon content to improve yield strength and tensile strength. The most common steel grade is Grade C A283.
