Chrome Balls -
AISI-52100 / SAE 52100


Martensitic Steel Profile
This fine-grain, martensitic steel is the result of years of experimentation
and analysis in search of the best material for bearing use. This is an
excellent material for chrome balls in load-bearing applications, and in
applications as diverse as food grinding systems, vibratory finishing,
plating baths, linear motion components, and check valves.
Other applications that are ideal for chrome balls manufactured by
Hartford include tumbling media, spray can agitation, ball bearings,
drawer slides, writing instruments and locking mechanisms.
If you manufacture valves, Hartford has extensive capabilities and
expertise for the design and manufacturing of balls for valves.
