ASTM A794

Full Name

ASTM A794 – Standard Specification for Commercial Steel (CS), Sheet, Carbon (0.16% Maximum to 0.25% Maximum), Cold-Rolled

Scope

ASTM A794 is a standard specification for commercial steel (CS) sheet, specifically for carbon steel with a carbon content ranging from 0.16% to 0.25%. These materials are cold-rolled, which means they are formed at room temperature.

Key requirements:

  • Chemical composition: specifies maximum and minimum allowable limits for elements such as carbon, manganese, phosphorus, sulfur, silicon, copper, and other alloying elements.
  • Tensile properties: defines minimum requirements for tensile strength, yield strength, and elongation.
  • Hardness: sets maximum limits for hardness to ensure adequate toughness.
  • Surface finish: specifies the allowable surface imperfections.
  • Formability: specifies the ability of the steel to be formed without cracking or splitting.

Applications – ASTM A794 steel sheet is used in a wide variety of construction and industrial applications, including:

  • Automotive components
  • Appliances
  • Building materials
  • Sheet metal fabrication
