ASTM A635

Full Name

ASTM A635 – Standard Specification for Steel, Sheet and Strip, Heavy-Thickness Coils, Hot-Rolled, Alloy, Carbon, Structural, High-Strength Low-Alloy, and High-Strength Low-Alloy with Improved Formability, General Requirements for

Scope

ASTM A635 is a standard specification for heavy-thickness steel sheet and strip, covering a wide range of carbon, structural, high-strength low-alloy, and high-strength low-alloy steel grades with improved formability. These materials are commonly used in construction and industrial applications where high strength and durability are required.

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.
  • Impact properties: specifies minimum requirements for impact resistance at a specified temperature.
  • Bend test: requires the steel sheet or strip to pass a bend test to demonstrate its ductility.
  • Hardness: sets maximum limits for hardness to ensure adequate toughness.
  • Formability: Specifies requirements for the steel’s ability to be formed without cracking or splitting.

Applications – ASTM A635 steel sheet and strip are used in various construction and industrial applications, including:

  • Structural components
  • Heavy equipment
  • Machinery
  • Pressure vessels
  • Boilers
