[QUOTE="Trickymissfit, post: 748069, member: 25383"] I had to learn on the fly with this stuff. Managed to get ahold of Vito Mitkus, and he made some calls to the right people to get me headed in the right direction. Vito was extremely knowledgable in stainless alloys, but was not upto par with machining it. (what he said anyway). I pretty much knew about the rust factor from classes he taught me years prior, never heard of these new series of stainless steels (I think there is also a 15-5 and maybe one with higher number than 18-5). I'd give you exact specs on machining the stuff, but I'm bound by a "non disclosure agreement" with an attached penalty, and also a similar device from TACOM. So that's why I was somewhat vague. Best data will probably come from Valenite or Kenmetal, and I'll stop at that. Lastly the metal is pretty hard on machinery unless it's over built. Really hates light cuts. If you ever decide to make parts out of 17PH4, the best I found is MAR-10 from Baldwin Steel in PA. Be prepaired to pay thru the nose as it's pretty expensive! But as bad as I've made it out to be, It's nothing compaired to Hestalloy castings!! I don't wish that stuff on anybody gary [/QUOTE]
