Turco II

[J. Neilson]

Where can I get this stuff, I promised some to a friend. I didn't see it in any of my catalogs or general searchs. Thanks.

K&G used to carry Turco.

what is it?

what is it?

It is a dip that prevents scale during heat treat, if you don't/can't use HT foil.

Turco is a liquid you dip your blades in before heat treat to prevent oxidadation and scale forming while the blade is in the oven. I havent had good luck with the stuff. It caused pits in my blades and I had to regrind anyway.

J as mentioned above K & G has it listed in their 2004 catolog for $24.75 a quart and $82.95 for a gallon. You can reach K&G at 800-972-1192.

Thanks guys, I must be blind as a bat cause I never saw it. I don't play around with this stuff, a friend is HT'ing some ATS-34 blades for me (yeah, yeah I know!) and I wanted to get him some Turco since he's almost out. That's perfect though...I've got a huge batch of wood they're stabilizing for me right now. So I'll just have them send the Turco also. Thanks guys, your always there to help me out.

Turco's max temp high enough for ATS34? You don't want to go overtemp with these coatings even 25-50F. Turns very acidic and pits terribly.

It must be OK Fitzo, I have one purveyor who wanted ATS-34 and since I don't normally do stainless (as Peter/Don says "it'll never catch on") I left it to a friend who does mostly ATS-34. The blades came back clean and cut like a bugger. Can't replace high carbon though...

I use Turco for tool steels. It is OK up to the 1875°F I harden D2 at. You need to give 2 full coats with time to dry in between. Then there is not a pitting problem.

I made the mistake of using it on four S30V blades and they were ruined. Apparently somewhere between 1875° and 2000°, the Turco burns off.

Turco turns very corrosive above 1800.It will etch or pit stainless.It is great for carbon steel blades.I use it on any that I do in the oven.Does not work very well in the forge.

I know the blades that are done for me are done in an oven (looks like R2-D2 for Star Wars). Is there a difference between Turco and Turco II? I'm assuming there is.
