-title: Hot Rolled Steel
-model: DC01/DC03/DC04
+title: Chromium-Coated Steel Sheet
+desc: Chromium-coated steel strip is a steel strip product with a uniform layer of metallic chromium electrochemically plated on the surface of cold-rolled or hot-rolled low-carbon steel substrate. Its core functions are to improve the corrosion resistance, hardness and decorative properties of steel, while extending service life.
+models: The ordering standard for electroplated chromium plates is Q/B QB455, which is non-equivalent to JIS G 3315, DIN EN 10202, EN 10203.

+## Characteristics
+### Chromium-Coated Steel Sheet Characteristics
+| Performance Feature | Description |
+| --- | --- |
+| Excellent paint adhesion | Paint adhesion far exceeds that of tinplate, can be used to manufacture DRD cans and glued cans. |
+| Excellent heat resistance | High temperature baking resistance, material performance does not deteriorate. |
+| Excellent anti-sulfurization performance | Metallic tin layer has good anti-sulfurization performance, suitable for canned food rich in protein. |
+| Excellent resistance to filiform corrosion | Excellent resistance to filiform corrosion under the paint film. |
+| Excellent alkali resistance | Chromium coating is a non-amphoteric material, more suitable for packaging alkaline contents such as cleaners and pigment dispersants. |
+
+### Different Characteristics between TFS and ETP
+| Performance Name | Description |
+| --- | --- |
+| Appearance | Paint adhesion far exceeds that of tinplate, can be used to manufacture DRD cans and glued cans. |
