SOME OTHER INFORMATION ABOUT 304 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 :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
1. OEM Services is ok for us.
2. Good Aftersale service.
3. Timely answering.
4. Good Quality Guarantee.
Quality assurance
1.The raw material control: strictly purchase the regular steel factory wire, provide the quality assurance certificate, meet the national standard requirement;
2.The production process: strictly follow the production operation procedure, and implement the 5S management.
3.Quality test check: first by machine, then by manual inspection, the rate of non-conformity is less than one in 10,000.
4.Packing: import antirust oil and seal packaging to ensure the storage is not rust.
production process of steel ball:
1.HEADING:
In the first step,heading machines cut wire into short lengths and form it into spherical shapes between dies.
2.FLASHING:
A process that bives a ball blank a rough finish and removes the excess material around the ball.
3.HEAT-TREATING:
Harden the balls by subjicting a metal of alloy to controlled heating and cooling to improve hardness and other properties.
4.HARD GRINDIGN:
Slow and meticulous grinding assures proper sizing and sphencity;
5.LAPPING:
This process has two steps,first is simple lapping,then is fine grinding.Both fo them is to plosh the balls to a shiny finish and to the exact size required by ISO 3290 GRADE.
6.CLEAN:
First clean the surface of balls;then use the dehydrated oil to dry off the balls;the last step is applying antirust oil for the balls.When these steps bave done,each ball will be selected by machine or naked eye to make sure every ball is perfect..
7.Inspection:
Each batch of products will accept measurement and inspection by the special inspectors.to check whether the products consistent with the customer's requirement.
8.Packing:
The balls are packed in anti-oxidant or liled paper ,in cardboard boxes of standard size with fixed quantities,finally in p alled or wooden cases .Packing will be sea&air worthy.Special packaging can be provided on request.
