 Round Precision Steel Balls Good Wear - Resistance High Hardness AISI1085

20mm Harden High Carbon Steel Iron Balls Bicycle Carbon Metal Grinding Balls AISI1085​


The density of this material, chrome steel, is .283 pounds per cubic inch ( 7.85 g/ cm³ ).
This material is strongly attracted by a magnetic field.
In the hardened condition, this material can be ground, honed, and lapped using conventional abrasives. It can be shaped and drilled using electrical discharge machining or ultrasonic cavitation. In the annealed condition, this material can be machined using normal techniques.

Carbon steel balls are made from a combination of steel and carbon, with carbon present in concentrations lower than 0.093%.


The carbon acts as a hardening agent, providing additional strength, at a lower cost than alternative hardening techniques.


They can be used in anything from furniture castors to sliding rails, polishing and milling machines, peening processes,


and welding appliances, depending on the type of carbon steel balls you choose.


Carbon steel balls have excellent surface quality ,high hardness and high load bearing capacity as a result of through hardening.


According to the different materials can be divided into Low carbon steel ball Medium carbon steel ball and High carbon steel ball,


The main material is 1010-1015,1045,1085


According to the hardness can be divided into Soft ball(HRC28) and hard ball (HRC55-60 after heat treatment).
