Alloy tool steel 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..
