Zinc coated (galvanized) low carbon steels for cold forming

البدائللا يوجد بديل لهذه الورقة.

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
