Product introduction

Tin Free Steel (TFS)

Electrolytic chromium coated steel also called Tin Free Steel(TFS) is an electrolytic chrome plated steel consisting of a thin layer of chromium and a layer of chromium oxide deposited on the steel base.It has a beautiful, metallic luster as well as excellent properties in corrosion resistance and paintability.

Main Advantages

1.Excellent resistance to Sulphur Blackening: The metallic chromium in tin free steel has excellent sulphide resistance property when canning protein-rich foodstuff such as fish.TFS compensates for the expensive sulphur resistant lacquer.

2.Excellent heat resistance: High-temperature baking causes neither discoloration nor deterioration in material properties.

3.Excellent filiform rust resistance: TFS has a excellent under film corrosion resistance.

4.Excellent paint adhesion: TFS has excellent paint adhesion properties that far surpass those of ETP, allowing its use for making DRD cans and adhesive bonde cans.

5.Excellent alkali resistance: The coating in TFS is not amphoteric. Alkaline products such as detergents and dispersion colours can be packed in TFS with advantage.
