(OP)
Can anyone recommend a commonly-availiable stainless steel with low galling from which I can manufacture washers.  I need the finished washer to be hard >50 HRC.

RE: Stainless Washer material

You are going to need a martensitic stainless steel (410 , 420) not to bad about galling.  If you need some more corrosion resistance you may need to use 440A or 440C.  Also if you can use a lower hardness say 45 to 50 HRc there many other options.   If anti-galling is all you desire a washer from Nitronic 60 or one of the other anti-galling alloys might work.  

Come back with the corrosion resistance needed and the size.

I have had good luck with the following company.  I would talk with them about your requirements.

Thanks,

I've decided to give 420 a go.  For your info, I found some very good material/heat treatment info at the following site:
