▎Product Overview
Brief Description: Tin-Free Steel (Electrolytic Chromium Coated Steel, ECCS) is a cold-rolled low-carbon steel sheet coated on both sides with a thin dual layer of metallic chromium and chromium oxide. The coating delivers excellent lacquer adhesion, corrosion resistance after coating, high hardness and heat resistance—making TFS ideal for ends and closures across food, beverage and general-line packaging.
▎How it protects
TFS protects via a dual chromium coating: a metallic chromium underlayer topped with a chromium-oxide film that creates strong chemical anchor sites for primers, lacquers, and inks. After coating and baking, the lacquered system forms a continuous barrier that delivers excellent corrosion resistance—including sulphide-stain resistance—while the hard chromium surface adds abrasion durability. Because the surface is chromium, it is not readily solderable; parts are typically joined by electric-resistance welding or by adhesive/cementing.
▎Key Features
 Corrosion resistance (with lacquer) Stable against a wide range of contents; excellent sulphide-stain resistance. |  Outstanding Paintability & Printability Strong adhesion to primers, lacquers and inks; supports high-temperature baking with good color retention. |  Good Formability & Rigidity Multiple temper grades for curling, flanging and seaming; suitable for stamping and shallow draw. |  Scratch & Abrasion Resistance Hard, uniform surface helps maintain decoration quality. |  Clean, Uniform Appearance Matte/stone finish for premium decoration and barcode readability. |  Process Note TFS is not solderable; typically used with organic coatings and joined by welding or adhesive/cementing. |
