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 316 stainless steel offers superior corrosion resistance due to the higher nickel and molybdenum content.

Stainless Steel - 316
  • Type Analysis-AISI - 316
    C 0.08; Cr 16 ~ 18; Ni 10 ~ 14; Mo 2 ~ 3; Mn 2; Si 1; P 0.045; S 0.030
  • General Information
    Similar to type 302, but the addition of Molybdenum improves to corrosion resistance. Deceloped to effectively resist the corrosion of sulphuric acid compounds, it is now used bery extensively.
  • Material Characteristics
    This steel has higher tensile and creep strength at elevated temperature than conventional 18-8 alloys. All balls of this material are passivated.
  • Hardness
    Annealed Rockwell B- 75 to 95 measured on parallel flats, not annealed, Rockwell C-39 maximum measured on parallel flats.
