ASTM A500 Welded Carbon Steel Tubing Cold-formed description
A500 standard welded pipe is typically made of carbon structural steel and formed using a cold forming process. According to the ASTM A500 standard, square pipes are classified into several grades, including Gr.A, Gr.B, and Gr.C, with varying yield strengths and tensile strengths. For example, Gr.B grade square pipes typically have a yield strength of no less than 290 MPa and a tensile strength between 400 and 550 MPa, meeting the requirements of most building frames and mechanical supports.
ASTM A500 GRA GRB GRC GRD Specification
astm a500 grade a yield strength
The minimum yield strength for ASTM A500 Grade A is 33,000 psi for round tubing and 39,000 psi for shaped tubing. This value can also be expressed as 228 MPa or 269 MPa respectively. It is important to check the specific product specification to confirm the minimum yield strength for the intended application and shape, as the value differs between round and shaped tubing.
astm a500 grade b yield strength
The minimum yield strength for ASTM A500 Grade B is46,000 psi (315 MPa). This is a common specification for structural tubing used in load-bearing applications.
astm a500 grade c yield strength
The yield strength of ASTM A500 Grade C is 50,000 psi (345 MPa) for shaped (square and rectangular) structural tubing. For round structural tubing, the minimum yield strength is 46,000 psi (317 MPa). This grade has a minimum tensile strength of 62,000 psi( 425 MPa).
astm a500 grade d yield strength
The minimum yield strength for ASTM A500 Grade D is 36,000 psi( 250 MPa). Its minimum ultimate tensile strength is 58,000 psi (400 MPa). Grade D is a heat-treated grade, and the yield strength applies to both round and shaped structural tubing.
