Product Description
SA240/SA240m Type 304L Stainless Steel Plate
Hot Finished in Solution Annealed Pickled and Passivated No. 1 Finished
Product Overview
SA240/SA240M Type 304L Stainless Steel Plate is hot finished in solution annealed, pickled and passivated condition with NO.1 surface finish, providing excellent corrosion resistance and mechanical properties for industrial applications.
Surface Treatment Characteristics
| Surface Finish | Characteristics and Applications |
|---|---|
| NO.2B | Better surface brightness and flatness than NO.2D. Through special surface treatment to improve mechanical properties, suitable for comprehensive applications. |
| 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 striations. 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. Primarily used for building ornaments, elevators, building doors, and frontal plates. |
| BA | Cold rolled, bright annealed and skin-passed. Excellent brightness and good mirror-like reflexivity 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 an ideal material for numerous applications. The alloy is suitable for cookware, cutlery, household hardware, surgical instruments, major appliances, industrial equipment, and as an automotive and construction material in large buildings. It is particularly valuable in 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
