ASTM A879
Full Name
ASTM A879 – Standard Specification for Steel Sheet, Zinc Coated by the Electrolytic Process for Applications Requiring Designation of the Coating Mass on Each Surface
Scope
ASTM A879 is a standard specification for steel sheet that is coated with zinc using an electrolytic process. This standard is unique in that it requires the coating mass on each surface of the steel sheet to be designated, providing more specific information about the corrosion protection provided by the zinc coating.
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 for each surface of the steel sheet.
- 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 A879 electrolytic zinc-coated steel sheet is used in various construction and industrial applications, including:
- Automotive components
- Appliances
- Building materials
- Sheet metal fabrication
