Stainless Steel Balls

BALCO INDUSTRIES stainless steels offer excellent corrosion resistance in organic, acid, industrial and marine environments. The non-magnetic properties combined with exceptionally high toughness at all temperatures make these steels an excellent selection for many applications. AISI 304 stainless steel offers superior corrosion resistance due to the higher nickel and molybdenum content.

Stainless Steel - 304
  • Type Analysis-AISI-304
    C 0.08 ~ Cr 18 ~ 20, Ni 8 ~ 10.5; Mn 2; Si 1; P 0.045, S 0.030.
  • General Information
    Type 18-8 stainless Steel Balls are used when conditions qualities and toughness of material not available in harden able stainless. Its principal application is in the value and related fields.
  • Material Characteristics
    Extreme toughness, low magnetic permeability, high tensile strength at elevated temperatures and resistance to scaling. This material work hardens quite rapidly. All balls of this material are passivated.
  • Hardness
    Annealed Rockwell B-75 to 95 measured on parallel flat. Not annealed Rockwell C039 maximum meadured on parallel flats.
