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.

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 sulphur acids

Typical hardness

Annealed: Rockwell B 75-95

Not annealed: Rockwell C 25-39
