The A36 standard was established by the standards organization ASTM International.

Properties

As with most steels, A36 has a density of 0.28 lb/in³ (7.8 g/cm³). A36 steel in plates, bars, and shapes with a thickness of less than 8 in (200 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.

A36 is a standard carbon steel, without advanced alloying.

Usage

Fabricated forms

A36 is produced in a wide variety of forms, including:

• Plate
• Structural Shapes
• Pipe
• Bar
• Sheet

For more information, see Structural steel.

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.
