Metal balls are rolling, spherical elements that are used in check and ball valves, bearings, and other mechanical devices that provide rotary or linear motion. They are usually made from alloy steel, carbon steel or stainless steel. Metal balls are characterized by the Outer Diameter, Permissible Deviation, Surface Roughness and Tolerance. The Outer Diameter (OD) is the overall width or average diameter of the ball.
The main advantage of the Chrome steel ball is that the hardness can reach HRC62-65 degrees, the wear resistance of the material is good, the precision of the cold made steel ball can reach 1/10000 mm, and the surface is mirrored. The color is chrome, and the only disadvantage is that it cannot be welded.
Heading:
In the first step, heading machines cut wire into short lengths and form it into spherical shapes between dies.
Deflashing:
The flash line, a ridge left by the forming dies, is removed as balls roll between heavy,cast iron plates.
Soft Grinding:
Similar to deflashing, except that a grinding stone is used to improve precision.
Heat-treating:
Carbon steel balls are next carburized and hardened. Heat treatment imparts the desired hardness and case depth.
Descaling:
This step removes the residues and by-products from the heat-treating process.
Hard Grinding:
Slow, meticulous grinding assures proper sizing and sphericity, with tolerances as closeas ±.0001".
Lapping:
Several proprietary lapping processes can bring balls to the requirements of ISO 3290 Grade10 - 48.
Finishing:
Proprietary chemical and mechanical processes give the balls their final micro-smoothed finish, for increased wear resistance and product longevity.

Before packing, the steel balls are sent to check the surface roughness, roundness, waviness, lot size variation and hardness in a sophisticated laboratory, according to specified control plans and dock audit procedures.
