ASTM A591
Full Name
ASTM A591 – Standard Specification for Steel Sheet, Electrolytic Zinc-Coated, for Light Coating Mass Applications
Scope
ASTM A591 is a standard specification for steel sheet that is coated with zinc using an electrolytic process. This type of coating is typically used for applications where a lighter zinc coating is desired compared to hot-dip galvanized steel.
Key requirements:
- Steel base: specifies the type of steel used as the base material for the zinc coating.
- Zinc coating: defines the minimum zinc coating weight per unit area.
- Surface finish: specifies the allowable surface imperfections.
- Mechanical properties: sets minimum requirements for tensile strength, yield strength, and elongation.
- Formability: specifies the ability of the steel to be formed without cracking or splitting.
Applications – ASTM A591 electrolytic zinc-coated steel sheet is used in various construction and industrial applications, including:
- Automotive components
- Appliances
- Building materials
- Sheet metal fabrication
