4.763mm 3.175mm 2.381mm AISI420C SUS304 AISI316 stainless steel ball (SGS ISO approved)

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.

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 

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.
