321 Quality Sheet Specification
Zinc coated (galvanized) low carbon steels for cold forming
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.

- Transverse and longitudinal test values are the same. Tensile tests are carried out only in the transverse direction and specified in the certificate. And also longitudinal test values are guaranteed.
- The mechanical properties are valid for a period of 6 months from the date on which the products are made available.
- Average Plastic Strain Ratio (ravg) is calculated as a weighted average of the individual r-values, i.e., ( r0+r90+2r45) / 4
