We have two factory to specially produce stainless steel ball,one is in shandong province,other one in henan province.
Austenitic/ferritic/martensitic stainless steel balls, they can be provided in the annealed, cold worked, hardened, magnetic or not magnetic state. The wide variety of steels allows to choose the right material when high corrosion resistance or hardness or mechanical/wear and abrasion resistance properties are demanded.
fair corrosion resistance
used for special bearings and valves where
Balls requiring a combine -action of hardness and
Magnetic, highest hardness,
good corrosion resistance
used in bearing nozzles and valves where
lubrication is poor or absent
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.
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.
Characteristics same as 316 but
with excellent corrosion resistance,
Lower carbon content than regular 316.
expecially used in Jewelry,
and Human Implant Applications
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.
