A36 steel is a common structural
steel
Steel is an alloy made up of iron with added carbon to improve its strength and fracture resistance compared to other forms of iron. Many other elements may be present or added. Stainless steels that are corrosion- and oxidation-resistant ty ...

[''Steel Construction Manual'', 8th Edition, second revised edition, American Institute of Steel Construction, 1986, Ch. 1 pp. 1–5.] The A36 (UNS K02600) standard was established by the
ASTM International. The standard was published in 1960 and has been updated several times since. Prior to 1960, the dominant standards for structural steel in North America were A7 (until 1967) and A9 (for buildings, until 1940).

Chemical composition
Note: For shapes with a flange thickness more than 3 in (76 mm), 0.85-1.35% manganese content and 0.15-0.40% silicon content are required.
Properties
As with most steels, A36 has a density of . Young's modulus for A36 steel is 200 GPa.ultimate tensile strength
Ultimate tensile strength (UTS), often shortened to tensile strength (TS), ultimate strength, or F_\text within equations, is the maximum stress that a material can withstand while being stretched or pulled before breaking. In brittle materials t ...

Fabricated forms
A36 is produced in a wide variety of forms, including:
* Plates
* Structural Shapes
* Bars
* Girders
* Angle iron
* T iron
Methods of joining
A36 is readily welded by all welding processes. As a result, the most common welding methods for A36 are the cheapest and easiest: shielded metal arc welding (''SMAW'', or ''stick welding''), gas metal arc welding (''GMAW'', or ''MIG welding''), and oxyacetylene welding. A36 steel is also commonly bolted
