The difference of stainless steel ball
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: 2mm
Best precision :G100
Hardness :HRc25-39
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 :2mm
Best precision :G100
Hardness :HRc25-39
Stainless steel (AISI 316L)
AISI 316L type stainless steel ball has lower carbon content than AISI 316 material, which offers ever higher corrosion resistance, also gives excellent resistance to sulphuric acid compounds. Usually used in valves, jewelry and medical uses.
AISI 316L steel ball in our factory:
Minimum diameter :2mm
Best precision :G100
Hardness :HRc25-39
Stainless stel (AISI 420)
AISI 420 have good hardness and fair-to-good corrosion resistance and strength, it is generally used for all applications requiring resistance to corrosion such as bearings, valves, writting instruments, food environment, fresh water, many petroleum products and mild acid environments. AISI 420 is also magnetic.
AISI 420 stainless steel balls in our factory:
Minimum diameter :1.2mm
Best precision :G10
Hardness :HRc52
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: 1.2mm
Best precision: G10
Hardness: HRc52
Stainless steel (AISI 440)
AISI 440 type stainless steel balls are used extensively in steel ball bearing that require hardness, dimensional stability, corrosion resistance and toughness. 440 ball are resistant to corrosion from fresh water, steam, crude oil, gasoline, perspiration, alcohol, blood and food stuffs. Maximum resistance to corrosion and tarnishing is only achieved when 440 balls are fully hardened and surface are polished to a high luster. 440 balls are also magnetic.
AISI 440 stainless steel balls in our factory:
Minimum diameter: 1.2mm
Best precision: G10
Hardness: HRc60-67
Stainless steel (AISI 440C)
AISI 440C steel balls offer the maxmum in strength and fair corrosion resistance among stainless material, they also have good hardness, so 440C steel balls usually used in bearings, valves and so on.
AISI 440C stainless steel balls in our factory:
Minimum diameter: 1.2mm
Best precision:G10
Hardness:HRc60-67
Our high precision bearing steel balls is G10. (ball diameter variation is in 0.25um)
Following is our inspection for G10 steel balls:
1. Each size of chrome steel balls have their own standard balls which are imported from Japan.
2. These standard balls were stocked into antirust oil at the temperature 20° C.
3. Our size measurement instrument's precision is up to 0.1um. Also import from Japan.
4. We will check the diameter, hardness, surface, deviation from spherical, vibration value and so on.
