382 Quality Sheet Specification
Zinc coated (galvanized) bake-hardening steels
AlternativesThere is no alternative to this sheet.
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.

- BH value is obtained at 170°C in 20 minutes.
- Average Plastic Strain Ratio (ravg) is calculated as a weighted average of the individual r-values, i.e., ( r0+r90+2r45) / 4
- The mechanical properties are valid for a period of 3 months from the date on which the products are made available.
- Tensile test values apply to "longitudinal" test pieces
