Chrome Steel Balls
AISI 52100 / 100Cr6 / SUJ2 / GCr15

The fine-grain martensitic steel used in Hartford chrome steel balls has high hardness and exceptional surface characteristics. It is an excellent material for chrome steel 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.

Chrome steel balls demonstrate high hardness, resistance to deformation, and excellent wear characteristics. Chrome balls from Hartford are manufactured from the highest quality chrome alloy electric furnace steel, and through-hardened for maximum strength and service life.
