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

- General
Information
Balls of this straight chromium steel are Designed to
provide stainless properties with maximum hardness. They
are always used in a hardened condition and in some
respects be have similar to steels.
- Material
Characteristic
Outstanding
characteristic is high hardness. Material is ferro-magnetic
and makes a fair permanent magnet. As hardened ball, not readily
machinable. All balls of this material are oassivated.
- Hardness
Rockwell
C-58 to 65 measured on parallel flats.
