annealling carbon damascus ?
I have a bar of carbon damascus O1 L6 that was not annealled properly. I did manage to cut it but took a bunch of teeth off my bandsaw blade. Then I tried to drill it with HSS bits and they would go in about 1/16 then simply stop. I tried a couple of spots and they were the same. I have a kiln for heat treating and was wondering what I can do to anneal the billet. I was thinking that if I took it to 1400 then just left them in the kiln to cool they should anneal. Would that work or is there something else I should do?
Thanks for the help. Steve __________________ Stephen Vanderkolff Please come on over and check out my website. http://www.vanderkolffknives.com/ Thanks

SVanderkolff, I have been working with that mix for my entire career, and I can fully confirm what you have discovered, traditional anneals will not work. Spheroidizing is an option with other steels but it is a necessity for this mix. Heat to 1375F, hold for 45 minutes to 1 hour and then cool no faster than 50F/hour to below 900F.
