Low magnetic permeability: annealed, 1.003; cold worked, 1.10; severely cold worked, 10.0. High tensile strength at elevated temperatures. 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 solutions, and most organic chemicals. They are susceptible to attack by halogen acids and moderately resistant to sulfur acids.

Typical Hardness

Annealed – Rockwell B 75-95. Not annealed – Rockwell C 25-39.

Ball Sizes:

Available in sizes from 1.5mm to 50.8mm in grades 50 through 1000.
