Product Description
304 Stainless Steel Color Sheet Gold Mirror Finish
ASTM A240 304 stainless steel sheet with golden mirror finish, available in various surface treatments including 2B, No.1, No.4, HL, BA, and 8K.
Surface Treatments & Characteristics
| Surface Finish | Characteristics and Application |
|---|---|
| NO.2B | Better surface brightness and flatness than NO.2D. Through special surface treatment to improve mechanical properties, nearly satisfies comprehensive uses. |
| NO.1 | Surface finished by heat treatment and pickling or corresponding processes after hot rolling. |
| NO.4 | Polished with abrasive belt of grit #150-#180, better brightness with discontinuous coarse stria, thinner than No.3. Used for bathtubs, building ornaments, electrical appliances, kitchen utensils, and food processing equipment. |
| HL | Polished with abrasive belt of grit #150-#320 on NO.4 finish with continuous streaks. Mainly used for building ornaments, elevators, building doors, and frontal plates. |
| BA | Cold rolled, bright annealed and skin-passed. Excellent brightness and good reflexivity like mirror. Used for kitchen apparatus and ornaments. |
| 8K | Excellent brightness and preferred reflexivity, can be used as mirror. |

Corrosion Resistance
Stainless steel's resistance to corrosion and staining, low maintenance requirements, and familiar luster make it ideal for many applications. The alloy is used in cookware, cutlery, household hardware, surgical instruments, major appliances, industrial equipment, and as automotive and construction material in large buildings. It is particularly suitable for commercial kitchens and food processing plants as it can be steam-cleaned and sterilized without needing paint or other surface finishes.
Applications
- Food preparation equipment, especially in chloride environments
- Chemical processing equipment
- Laboratory benches and equipment
- Rubber, plastics, pulp & paper machinery
- Pollution control equipment
- Boat fittings, valves and pump trim
