Product Description
Hairline 304 Stainless Steel Sheet with No. 4 Finish
Our 304 stainless steel sheets comply with ASTM A240 standards and are available in various surface finishes including 2B, No. 1, No. 4, HL, BA, and 8K to meet diverse industrial requirements.
Surface Treatments and Characteristics
| Surface Finish | Characteristics and Applications |
|---|---|
| NO.2B | Superior brightness and flatness compared to NO.2D, with enhanced mechanical properties through special surface treatment for comprehensive applications |
| NO.1 | Heat treatment and pickling finish after hot rolling process |
| NO.4 | Polished with #150-#180 grit abrasive belt, featuring better brightness with discontinuous coarse striations. Ideal for bathtubs, building ornaments, electrical appliances, kitchen utensils, and food processing equipment |
| HL | Polished with #150-#320 grit abrasive belt on NO.4 finish with continuous streaks. Primarily used for building ornaments, elevators, architectural doors, and frontal plates |
| BA | Cold rolled, bright annealed and skin-passed with excellent brightness and mirror-like reflectivity. Suitable for kitchen apparatus and decorative applications |
| 8K | Excellent brightness with superior mirror-like reflectivity |

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
