AISI302/304/304L Stainless steel Balls—unhardened austenitic stainless steel balls,they display good mechanical characteristics.Balls are provided in the passivated condition.
Applications: special bearings and pumps,gardening and household sprayers,perfume miniature pumps,seams,medical application valves, agricultural backpack sprayers. They are used in foodstuff,aerospace and military industry.Â
Precision AISI 304/302 stainless steel balls  are used when conditions require corrosion performance and toughness not available in hard enable stainless steels
Principal applications are in couplings, valves and pumps
Characteristics:
Low magnetic permeability: annealed, 1.003, cold worked, 1.10, severely cold worked, 10.0
High tensile strength at elevated temperature
18-8 stainless steel work-hardens rapidly
AISI 304/302 stainless steel balls of this material are passivated
Corrosion resistance
Type 18-8 stainless steel balls resist attack by oxidizing solutions, foodstuffs, sterilizing solution and most organic chemicals
They are susceptible to attack by halogen acids and moderately resistant to the sulr acids
Typical hardness
Annealed: Rockwell B 75-95
Not annealed: Rockwell C 25-39
