Our Products
We are leaders in the market for providing best range of Ceramic Balls, Chrome Steel Balls and Stainless Steel Balls
Ceramic Ballsare mainly used in harsh environments. Their main advantages on steel is that they have a density 40% lower than steel, have 29% lower thermal expansion and are 150% harder. In certain high-speed applications their life is extended hundred times. It is also used as grinding media. 3 main types are-
| Alumina Oxide - Ceramic Balls | |

Chrome Steel Ballsare widely used in high speed ball bearings, valve industry, as well as, in a number of other industrial applications. Chrome steel balls have excellent surface quality, high hardness, high load bearing capacity and wear resistance, as a result of through hardening.
Chrome Steel Balls of 2mm OD, Hardness should be around 60HRC:
| Specification (stainless steel balls) | Hardness | Density |
|---|---|---|
| AISI 420 | 55/58 Hrc | 7.75 |
| AISI 440C | 58/64 Hrc | 7.75 |
| AISI 302 | 25/39 Hrc | 7.93 |
| AISI 304(L) | 25/39 Hrc | 7.93 |
| AISI 316(L) | 25/39 Hrc | 7.98 |
| AISI 904 | 150/300 HV | 8 |
| AISI 430 | 135/380 HV | 7.68 |
