Tinplate and TFS for Chemical or Industrial Useage

Product Description:

1.Structure of Tinplate and TFS for Chemical or Industrial Useage Description

Electrolytic Tinplate,is one thin steel sheet with a coating of tin applied by electrolytic deposition. Tinplate made by this process is essentially a sandwich in which the central core is strip steel. This core is cleaned in a pickling solution and then fed through tanks containing electrolyte, where tin is deposited on both sides. As the strip passes between high-frequency electric induction coils, it is heated so that the tin coating melts and flows to form a lustrous coat.

Also known as chromed steel, tin-free steel (TFS) is obtained by coating the metal base (low-carbon steel) with an ultra-thin layer of metallic chrome and then with a chromium oxide layer.

2.Main Features of the Tinplate and TFS for Chemical or Industrial Useage

Appearance – Tinplate is characterized by its beautiful metallic luster. Products with various kinds of surface roughness are produced by selecting the surface finish of the substrate steel sheet.

Paintability and printability – Tinplates have excellent paintability and printability. Printing is beautifully finished using various lacquers and inks.

Formability and strength – Tinplates have got very good formability and strength. By selecting a proper temper grade, appropriate formability is obtained for different applications as well as the required strength after forming.

Corrosion resistance – Tinplate has got good corrosion resistance. By selecting a proper coating weight, appropriate corrosion resistance is obtained against container contents. Coated items should meet 24 hour 5 % salt spray requirement.
