Carbon steel is classified according to the carbon content. The carbon content is less than 1.35%. In addition to iron, carbon and impurities such as silicon, manganese, phosphorus, and sulfur within the limit, the steel does not contain other alloying elements.
The performance of carbon steel mainly depends on the carbon content. As the carbon content increases, the strength and hardness of the steel increase, and the ductility, toughness and weldability decrease. Compared with other steels, carbon steel is the first to be used, with low cost, wide performance range and the largest amount.
Usually divided into low carbon steel (carbon content of 0.04% to 0.25%), medium carbon steel (carbon content of 0.25% to 0.6%) and high carbon steel (carbon content of 0.6% to 1.35%) according to carbon content.

In Ball Bearings
Grade 20, hardened chrome steel balls are applicable.
Manufactured in high carbon high chrome steel, also called bearing steel (AISI-52100 / EN-31)
Ball Diameter Tolerance: 0.000020 inch or 0.0005 mm or 0.50 microns.
Basic Diameter Tolerance: ± 0.0001" or ± 0.0025 mm or ± 2.50 microns
In Bicycles
Grade 200 or 500 are suitable.
Manufactured in hardened high carbon high chrome steel (AISI-52100 / EN-31 / EN-9 / M.S.)
Generally used diameter (in inches) are 1/8", 1/4", 3/16", 5/32"
In Automotive Sub-assemblies
Generally stainless steel balls, AISI 304 or 316; Grade 100 are used.
In Valves
Material AISI 304 and AISI 316 is used.
Grade 200, Basic Diameter Tolerance ± 25 microns.
Sizes 6 mm to 12.7 mm and 1/4" to 1/2" diameters.
As Agitators
In the plating bath for plating zinc and lead
In the plating baths, chrome steel balls of 1, 1.5 and 2 mm diameters are used. High tolerance is not required and hence, grade 1000 polished ball is generally suitable. At times, stainless balls of 304 steel are also used.
In paint spray cans
Here balls of 3/8" or 10 mm diameters, G-1000 are used. The steel balls stir up the paint and mix it thoroughly.
In personal care products like nail polish
Because of non-usage, the fluid coagulates and the bottle is shaken to homogenize the fluid and make it free flowing. The bottle contains a steel ball which is used as an agitator ball to help in achieving the above when the bottle is shaken. Because of the fluid, the steel balls can be prone to corrosion, hence AISI 316 stainless balls are preferred. 3 and 5 mm sizes (1/8" and 3/16" diameters) are generally used. Grade -1000 is suitable for this application.
As valve for spray pumps and dispensers
Stainless steel AISI-316 balls are used in spray pumps as a one way valve. SS-316 (Chromium 16-18%, Nickel 10-12%) has good corrosion resistance which is essential for personal care products and cosmetics. At times, in detergent pumps, AISI-304 stainless steel ball is used.
Tolerance of the steel ball ranges from G-100 to G-500 depending upon the quality and performance specifications of the overall product.
2, 3, 4 and 5 mm or 3/32", 1/8", 5/32" and 3/16 inch diameter balls are generally used.
Micro spray pumps in which these stainless steel balls are used include deodorant spray pumps, eau-de-cologne spray pumps, viscous liquid spray pumps (for liquid soap and detergents), gel pumps, toothpaste pumps, pocket spray pumps, spray pumps for metal container (without gas pressure) and insecticide spray pumps.

1. Wire Drawing
Each batch of raw material steel is inspected and classified according to different material (carbon, stainless, chrome), size and quantity, which marked with the Material Cert. The qualified steel comes to the quarantine area; the unqualified will be rejected with a record.
Then the steel is made into different sizes according to the needed requirements.
2. Cold Heading
The raw material certified is worked on high-speed casting machines to cast into different size pieces.
3.Ball Flashing
This step of the production process involves rolling the pieces between discs with concentric grooves to eliminate signs of casting and to increase the precision of the ball.
4. Heat Treatment
Heat treatment, where necessary, gives the balls the maximum possible hardness and the best technical characteristics that can be achieved with the materials used.
5.Hard Grinding
Successively several careful grinding processes using ceramic grinding wheels give greater dimensional precision and prepare the balls the next, final lapping process.
6.Lapping
This procedure gives the ball a perfectly shiny, compact and defect-free surface, with very low surface roughness, much lower than that required under GB/308-2002
7. Cleaning
Remove the oil stains on the surface of the steel ball , make the steel ball cleaner and brighter
8. Selecting and Final Inspection
The sorting machines together with the manual detecting and modern testing processes, largely ensures the high quality of our products.
9.Packaging
Pack products according to customer needs
