A36 steel
A36 steel is a standard steel alloy which is a common structural steel used in the United States.[1]
The A36 standard was established by the standards organization ASTM International.

[edit] Properties
As with most steels, A36 has a density of 0.28 lbm/cu in (7.8 g/cm3). 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). Young's modulus for A36 steel is 29×106 psi (200 GPa, 29000 Ksi)[2] . Plates thicker than 8 in have a 32,000 psi (220 MPa) yield strength and the same ultimate tensile strength.[1] A36 steel has a Poisson's ratio of 0.260, a compressive strength equal to the tensile strength and a shear modulus of 79.3 GPa. A36 is a standard carbon steel, without advanced alloying.
[edit] Usage
[edit] Fabricated forms
A36 is produced in a wide variety of forms, including:
- Plate
- Structural Shapes
- Bar
- Sheet
For more information, see Structural steel.
[edit] Methods of joining
A36 is readily welded by nearly all welding processes. The most commonly used for A36 are the cheapest and easiest—shielded metal arc welding (SMAW, or stick welding), gas metal arc welding (MIG welding), and oxyacetylene welding.
A36 steel is also commonly bolted and riveted in structural applications.
