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.
Coating Structure of Tin Free Steel
Production Process of Tin Free Steel
|Minimum Average Coating Weight||Maximum Average Coating Weigh|
|Metallic Chromium Layer (one side)||50 mg/m2||150 mg/m2|
|Chromium Oxide Layer (one side)||5 mg/m2||35 mg/m2|
|B||Bright surface||Glazed surface obtained by a thin layer of chromium and chromium oxide deposited on the smooth steel base with extremely fine stone figures by processing.|
|R||Stone surface||Glazed surface obtained after a thin layer of chromium and chromium oxide deposited on the smooth steel base featuring certain oriented stone figures.|
|R2||Stone rough surface||Glazed surface obtained after a thin layer of chromium and chromium oxide|
deposited on the smooth steel base featuring certain oriented stone figures,
roughness higher than “R”.
|M||Matte surface||Matt surface.|
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.
