AISI 440C Stainless Steel Balls

AISI type 440C stainless steel balls offer the maximum in material strength and fair corrosion resistanc. They resist alcohol, food environments, fresh water, many petroleum products, organic materials and steam. Type 440C balls are uses in bearings, valves, locking mechanisms, fasteners and quick-disconnect couplings.

AISI 304 Stainless Steel Balls

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.

AISI 316L Stainless Steel Balls

AISI type 316L stainless steel balls offer excellent corrosion resistance and resistance to sulphuric acid compounds. This austenitic steel includes 2-3% molybdenum. Type 316 balls are used in trigger sprayers, bearings, dispenser valves, body jewelry, lotion pumps, quick-disconnect couplings and aerospace applications. Type 316LVM balls are used in jewelry, human implant and other medical applications.
