steel to use for clutch/brake disks in lathe?
(OP)
Hello. We've been trying to find a source for clutch and brake disks for a metal lathe which is no longer supported. We finally took it apart and measured the disks. We are thinking about just having new disks cut on a waterjet machine, as there really doesn't appear to be any rocket science to them. There is no friction material, just steel and steel disks. The disks are too thin for us to measure their hardness. Can anyone suggest a suitable steel to use to make these?
Thanks!
Thanks!

I don't have anymore information as to the type or where we purchased it from but it was made by Theis. You might give Theis a call for recommendations and where you might be able to purchase the material as they are mill.
If no joy in this direction I have seen prehardened AISI 1065 used for similar applications.

Yes, these are wet devices. The clutches are in an oil bath gear box that drizzles oil over the disks. The brake disk stack appears to use the oil from its hydraulic actuator to keep the disks coated with oil.
I was thinking of some of the prehardened sheets from McMaster Carr, like 4140/42 or 1075 or 1095. Thanks.
