1415 Quality Sheet Specification
Zinc-iron alloy coated (galvannealed) low carbon steels for cold forming
Reproducible Letter Symbols --> GFR --> GFRD --> GFR
Flat / Galvanised
Galvanized flat steel is manufactured by zinc-coating both sides of cold rolled metal by hot-dipping process. After having coated the steel surface with zinc, the coating of the interface is transformed into an alloy of iron-zinc layer through heating by induction and the galvannealed steel is produced.

- Tensile test values apply to "transverse" test pieces
- For surface quality A, the upper value for yield strength is 360MPa.
- Guarantee period is valid for surface quality for B and C products.
- Guarantee periods of absence of stretcher strains marks and mechanical properties are 6 months. The period begin on the date on which products are made available.
