Screwing 17-4 stainless & nitronic 50 and galling issues.
Screwing 17-4 stainless & nitronic 50 and galling issues.
(OP)
I am trying to find a replacement for 17-4 that will screw into another part made of 17-4. We currently copper plate the threads (to prevent galling)when screwing 2 parts of 17-4 together, but the copper plate does not last when the tool is being broke down to replace seals almost daily. Would nitronic 50 be a good choice? The yeild stength is about half of h-1075, but this would not be an issue for this part. I read that nitronic 60 has better anti-galling properties, but my machine shop has some nitronic50 in stock. thanks for any suggestions/feedback

If you cut threads on Nit50 you will have some issues. Rolled threads will work much better.
I am sorry that the guys in the field are negligent. I was in the oilfiled equipment business and we simply prohibited the re-use of any fasteners. The field kits of new bolts were all silver plated and pre-lubed. The time saved was worth the cost.
