Hardness for low carbon steel balls, as measured on the balls surface is Rockwell "C" 60 (minimum) and subject to correction factors. See chart for minimum case depth.
Case depth reported is the effective case measured to the HRC 50 position (ref. ABMA Std. 10-83). Minimum thickness considerations apply to case depth.
Soft: Caddies, wrought iron work, curtain mechanisms, steel shots, munitions, stirrers and mixers in not aggressive environments, welding appliances.
Hardened: Furniture rails and rollers, drawers and rolling bearings, locks, oilers and greasers, skates, caddies, toys, belt and roller conveyors, tumble finishing.
Distinctively Shaped Ball: We offer a variety of flat, diagonally cut, cone and pin shaped balls that are typically used as hardened polishing and shaping tools.
For example, the diagonally cut and shaped balls can be used to polish surfaces with sharp angles.
Flat balls are typically used to polish uniformly shaped surfaces such as soins. Sizes and materials can be made available to suit your needs.

Drilled Ball: Zhongrui offers a full range of sizes, hole depths (including thru-
hole), diameters and materials.
Typical applications include body jewelry, earring posts, rings, seal slides, valves, and automotive engine push rods.
Plated Ball: Platings are used to enhance the physical properties of precision balls. These may include added hardness (titanium nitride),
corrosion resistance (molybdenum disulfide), noise supression (rubber), and
electrical characteristics (gold). zhongrui offers a myriad of plating to meet your needs.
Hollow Ball: Hollow balls are typically used for weight sensitive applications such as aircraft ball transfer units, liquid float systems, and custom ball valve
We provide 201, 304, 316 stainless steel hollow balls in a variety of sizes

Production Processing Line
Ball blanks are cold or hot headed from rolls of wire or bar stock depending on their size and the material. The heading machine cuts off a short cylinder of the material and a moving die with a concave spherical cup drives the cylinder into a matching cup in a fixed die. The result is a spherical shape which is the ball blank.
The flashing operation removes the slight belt and small protrusions left on the surface faces by rolling them between the two hard alloy plates under high pressure.
The balls are hardened, if required, by heating them to a high temperature (over 1500 degrees Fahrenheit) in an atmospherically controlled furnace and then quenching them into a liquid bath. They are then tempered to reduce their brittleness by heating them to a low temperature (around 325 Fahrenheit). Samples are checked for hardness. The grain size and metallurgical structure are inspected under a high power microscope.000
The hardened balls are precision ground by rolling them between the faces of a fixed iron plate and a very hard fine-grit grinding wheel.
The next step is the lapping operation. The hardened ground balls are rolled between two cast iron plates. One plate is fixed while the other is rotated at a very low speed. The real secret of the extreme quality of precision balls happens here. At this stage the sphericity and size have been established and are carefully inspected by ABMA customer requirements.
The final production operation is polishing which adds the shinny luster to the finished ball. The balls are then inspected visually and/or Aviko inspected.
