Carbon alloy balls are available in the following types: Low Carbon Steel Balls (case hardened)The main feature of this ball is the carburised
case with a soft core. This design lends resistance
to shock loads and surface wear while providing good
load carrying ability. Balls of this type are generally
used in applications where there are only moderate loads
and slow rotating parts. High Carbon Steel Balls (through hardened)
Balls of this material have the advantage of being through
hardened and will take higher loads and provide longer
life than case hardened balls, for such applications
as the cycle industry. These balls are substantially
cheaper than balls manufactured from high carbon chrome
alloy steels.
