Product Description
Material | Feature | General Applications |
AISI 420 | Magnetic, Harden-able, fair corrosion resistance | used for special bearings and valves where Balls requiring a combine -action of hardness and corrosion resistance |
AISI 440C | Magnetic, highest hardness, good corrosion resistance | used in bearing nozzles and valves where lubrication is poor or absent |
AISI 304 | austentitic, corrosion resistance, slightly magnetic, however annealing can makes it non - magnetic | Used in valves and relevant application , food products, aerosols, home sprays, perfumes and medical equipment. |
AISI 316 | non - magnetic, good corrosion resistance even when exposed to marine atmosphere and sulfuric acid. | used in presence of sulphuric, phosphoric and acetic acids. Mainly used in chemical, paper and textile industries. |
AISI 316 | Characteristics same as 316 but with excellent corrosion resistance, Lower carbon content than regular 316. | expecially used in Jewelry, and Human Implant Applications |

Production procession
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.
