Product Description
304 Stainless Steel 8K Sheet - Mirror Finish Stainless Steel
ASTM A240 304 stainless steel sheet with various surface treatments for comprehensive industrial applications.
Surface Treatments and Characteristics
| Surface Finish | Characteristics and Application |
|---|---|
| NO.2B | Better brightness and flatness than NO.2D. Through special surface treatment to improve mechanical properties, suitable for comprehensive uses. |
| NO.1 | Surface finished by heat treatment and pickling after hot rolling. |
| NO.4 | Polished with abrasive belt of grit #150-#180, better brightness with discontinuous coarse stria. 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. Used for building ornaments, elevators, 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 numerous applications. The alloy is used in cookware, cutlery, household hardware, surgical instruments, major appliances, industrial equipment, and as 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 requiring 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
