Hey I found a paper on Cryogenic processing of tungsten carbide inserts. And the best part, its not published by a cryo treatment company! here http://scholarbank.nus.edu.sg/handle/10635/12879

Thanks, I already got my piece from carbide processors, but I will archive you guys for next time.

sounds like your going to need carbide. If you have time, and money, or if this is a really important piece/hole, then you could get it water jeted. These guys do low production runs http://www.leadingedgefab.com/ often profiling, and drilling blanks for individual knife makers. It may be...

So I just ordered a custom carbide piece, where toughness is the main issue; and I am wondering if I should send it out for cyro treatment after I am done grinding it, or is this process too risky, as I cant afford a failure.

I was just looking at Cryo treating carbide to gain additional toughness, Could somebody (Fredrick?) please explain the mechanism at work here? I understand how Cryo treatment of steel works, but I am rather baffled by carbide. So if I just carefully dunk a piece of tungsten carbide in liquid...

Thanks, I had forgotten about stellites, i will look into that as well as some of the ohers

Thanks guys, I had seen some of those suppliers, but not all of them. Part of my problem is that I really only need a few pieces, and I am intimidated by some of the larger companies, and the associated cost of a custom-ish part. I need a grade that can support a very low edge angle without...

I am not really sure whether this belong here or in the ceramics forum as cemented carbide is a cermet, but anyway I have a rather specific carbide need. I need a 1/32"x 3/4"x 3" piece of C-14 or similarly tough, impact resistant, cemented carbide. Does anybody even make something like this?

If you like CPM M4 I think that M390 is its closest stainless equivalent, but D2, CPM 154 and the 440 etc. series should be just fine http://www.bohler-edelstahl.com/files/M390DE.pdf"]http://www.bohler-edelstahl.com/files/M390DE.pdf[/URL]http://www.bohler-edelstahl.com/files/M390DE.pdf
