AISI type 302 stainless steel balls are for applications where good corrosion resistance is important, but hardness is not. They offer good resistance to atmospheric corrosion, dyes, food, environmental sterilizing solutions and many organic and inorganic materials. Type 302 balls are used in dispenser and aerosol valves, lotion pumps, locking mechanisms, agitators, animal feeders, trigger sprayers, finger pumps, food processing and medical applications.
