Chromium-plated thin steel sheet, also known as tin-free thin steel sheet TFS or chrome-plated sheet, is a low-carbon thin steel sheet coated with chromium and chromium oxides on both sides. As a substitute material for tin-plated sheet, its corrosion resistance and weldability are comparable Tin plate is poor, but its price is low, so it is widely used in the bottom covers of beverage cans and food cans with less corrosion.
