Description

A36 steel is a standard steel alloy that is a common structural steel in the United States. The A36 standard was established by the standards organization ASTM International.

As with most steels, A36 has a density of 7,800 kg/m3 (0.28 lb/cu in). Young’s modulus for A36 steel is 200 GPa (29,000,000 psi). A36 steel has a Poisson’s ratio of 0.260, and a shear modulus of 79.3 GPa (11,500,000 psi).

A36 steel in plates, bars, and shapes with a thickness of less than 8 in (203 mm) has a minimum yield strength of 36,000 psi (250 MPa) and ultimate tensile strength of 58,000–80,000 psi (400–550 MPa). Plates thicker than 8 in have a 32,000 psi (220 MPa) yield strength and the same ultimate tensile strength. The Electrical Resistance of A36 is 0.0000153 ohm/cm. A36 bars and shapes maintain their ultimate strength up to 650°F. Afterward, the minimum strength drops off from 58,000 psi: 54,000 psi at 700°F; 45,000 psi at 750°F; 37,000 psi at 800°F.

SS400 STEEL PLATES on the other hand is mostly of Carbon and Low Alloy Steel which can bear low temperatures and seawater.
