Alloy tool steel ball
PRECISION BALL
Alloy tool steel balls have an excellent fatigue resistant at high temperature. Two types of standards can be distinguished:
– M50 balls for aerospace ball bearings : we use AMS 6491 (VIM-VAR) material and the heat treatment is certified NADCAP.
– M2, T15, M62 (CPM® REX® 20) balls for X Ray Tube ball bearing. Our manufacturing process can reach high quality surface (Grade 3) in order to get a low noise level under normal condition.
| Material | Steel grade | Density (Kg/dm3) | Hardness |
| Alloy tool steel ball | AISI M50 ball AMS 6491 | 7,80 | 60-65 HRC |
| AISI M2 ball (HS-6-5-2) | 8,10 | 62-65 HRC | |
| AISI T15 PM ball | 8,20 | 65-68 HRC | |
| AISI M62 PM ball (CPM® REX® 20) | 8,17 | 62-65 HRC |
For industrial applications we can supply the balls via our Supply Chain. In all cases, each batch is validated by our certified quality system based on aeronautical requirements.
