Current Topic:
What is the best material for a measuring gauge master part?

I concur with the A2 and O1 suggestions, but if you're thinking of a stainless steel I'd recommend something like Crucible's CPM S30V.  The powder metallurgy bearing steels like that one have a big advantage for gauge parts since the carbide particle size is small, and you can get the single digit surface finishes you need.

Good luck!
