Material for High Temperature Ballscrew
Material for High Temperature Ballscrew
(OP)
Hello all, I just joined this forum, hope I can contribute as well as get some direction.
I am a design engineer at a linear actuator supplier for aerospace applications, in particular ballscrew actuators.
We have recently seen a surge in the number of RFQ's for high temperature ballscrew actuators, one in particular I am working on currently will be operating in 700-800F though for a short time.
I am looking into possible materials and at this point have it narrowed down to 3-
Inconel 718
Waspaloy
A286
Thoughts, comments, suggestions, etc. would be welcome.
Thanks

You did not mention or provide your specific design constraints and environment as a basis for alloy selection so if you need comments regarding alloy selection, it would probably be useful to provide this information.

Full ceramic and hybrid metal-ceramic bearings are available.

If you need some corrosion resistance look at 17-7PH or Custom 455 or 465.

Corrosion, every where, all the time.
Manage it or it will manage you.
