Product Description
Hairline 304 Stainless Steel Sheet
Premium 304 stainless steel sheets available in various surface finishes including Hairline (HL), No. 4, No. 2B, BA, and 8K mirror finishes. Ideal for industrial, construction, and food processing applications.
Surface Treatments & Characteristics
| Surface Finish | Characteristics and Application |
|---|---|
| NO.2B | Better brightness and flatness than NO.2D, improved mechanical properties through special surface treatment, suitable for comprehensive uses |
| NO.1 | Heat treatment and pickling finish after hot rolling process |
| NO.4 | Polished with #150-#180 grit abrasive belt, good brightness with discontinuous coarse stria, used for bathtubs, building ornaments, appliances, kitchen utensils, and food processing equipment |
| HL | Polished with #150-#320 grit abrasive belt on NO.4 finish, continuous streaks, primarily used for building ornaments, elevators, doors, and frontal plates |
| BA | Cold rolled, bright annealed and skin-passed, excellent brightness and mirror-like reflexivity, suitable for kitchen apparatus and ornaments |
| 8K | Excellent brightness and superior mirror-like reflexivity |

Corrosion Resistance
Stainless steel's exceptional resistance to corrosion and staining, combined with low maintenance requirements and attractive luster, makes it ideal for numerous applications. The alloy is widely 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
