AISI Type 304 Stainless Steel
AISI type 304 stainless steel balls are used where good corrosion resistance is important, but hardness is not. They offer good resistance to atmospheric corrosion, dyes, food environments, sterilizing solutions and many organic and inorganic materials. Type 304 balls are used in aerosol and dispenser valves, medical applications, animal feeders, trigger sprayers, finger pumps and food processing.
