Stainless Steel in Water Applications
Low Surface roughness (only 0.15 to 0.25 m) a. Reduces deposits and film formation
b. Facilitates Cleaning
c. Makes chemical cleansers redundant
Strong material: Not easily damaged by use in PublicBuildings.
Wear resistant:
Remarkable for its abrasion and erosion resistance.
