Title: GunGard color case hardening Compound.
Post by: Rolf on August 07, 2010, 06:27:06 PM

Has any one tried Gungard color case hardening Compound? They have on Blackleys website.
 http://www.blackleyandson.com/acatalog/Compounds_and_Solutions_for_Metals.html

It seems easy to use. Somewhat like Kasenite. I copied the instructions.

"FILL CONTAINER WITH TWO PINTS OF TEPID WATER. ADD ONE TABLE SPOON OF SALT PETRE AND MIX. HEAT PART TO RED AND DIP INTO COMPOUND. REHEAT PART AND ALLOW THE COMPOUND TO MELT AND FLOW OVER SURFACE OF PART, AND PLUNGE INTO WATER. WASH OFF REMAINING COMPOUND."


Best regards

Hi Rolf,
I haven't used it but I suspect the salt peter in the quench enhances the colors because of the nitrogen.  I doubt you can achieve a deep hardening unless you keep the part in the heat for a long time.  I usually heat parts for 90 minutes packed in bone charcoal.
