Corrosion Resistance
Stainless steel's excellent resistance to corrosion and staining, combined with low maintenance requirements and attractive appearance, make it ideal for numerous applications. The alloy is widely used in cookware, cutlery, household hardware, surgical instruments, major appliances, industrial equipment, and automotive and construction components for 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
