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.
| 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. |
| Corrosion Resistance | High temperature baking resistance, no discoloration, material performance does not deteriorate. |
| Solderability | Metallic tin layer has good anti-sulfide performance, suitable for canned food rich in protein such as fish. |
| Weldability | Excellent resistance to filiform corrosion under the paint film. |
| Coating Weight | Chromium coating is a non-amphoteric material, more suitable for packaging alkaline contents such as cleaners and pigment dispersants. |
## Product Uses
| Material Name | Main Uses |
| :--- | :--- |
| Tinplate | Mainly used for packaging food and beverage cans, also used for packaging gasoline, grease, pigments, polishes, sprays and other chemicals. |
| Tin-free steel (TFS) | Mainly used as can lids, twist-off caps, convex caps, easy-open lids, shallow drawn cans. |
