Cheap Source for Low Temp Salts?

[Sando]

I know I've seen it before, but I can't find them now.

I'm looking for tempering salts - not bluing salts. 200-500 degree range stuff. But I can't it.

Help.

PS I did buy my high wattage lab hot plate on ebay. I plan on trying the warm oil quench and salt tempering on ATS-34 and S30V. This will be interesting.

Jeff Carlisle used to carry the commercial variety of low temperature salts that he sold by the pound. There is some contact information here:

Might cost about the same as Brownell's Nitre Blueing salts actually but are specifically formulated for heat treating.
