Stainless steel ball
Stainless steel (AISI 316)
AISI 316 steel balls have no good hardness, but have better corrosion resistance than AISI 304, AISI 316 stainless steel balls offer good corrosion resistance to sulphuric acid compounds. They are used in nail polish, trigger sprayers, dispenser valves, body jewelry and so on.
AISI 316 stainless steel balls in our factory:
Minimum diameter :0.4mm
Best precision :G100
Hardness :HRc25-39
Stainless steel (AISI 304)
There are many kinds of stainless steel balls, AISI 304, AISI 316, AISI 316L, AISI 420, AISI 420C, AISI 440, AISI 440C.AISI 304 steel balls have no good hardness but offer good corrosion resistance, they offer good resistance to atomospheric corrosion, dyes, food processing, valves, sex products and so on.
AISI 304 stainless steel ball in our factory :
Minimum diameter: 0.4mm
Best precision :G100
Hardness :HRc25-39
Stainless steel (AISI 420C)
AISI type stainless steel balls have the advantage of maximum hardness combined with corrosion resisting properties, 420C balls have a slightly higher hardness range than 420. Its fine surface finish, also makes them especiall useful in bearings and valves and other severe environment applications.
AISI 420c stainless steel balls in our factory:
Minimum diameter: 0.4mm
Best precision: G10
Hardness: HRc52-65
