Where to get Parks #50?


Recommended Posts

I was hardening a 1/4" thick Cleaver made from 1084, and had troubles getting it to harden in warmed Veggie Oil. While searching around for HT solutions for 1084, Parks came up, a LOT. Since it doesn't spoil, and is made for this and various other steels, I figured why not?

 

I did get it to harden in veggie oil today though. 130F and a lot of agitation did the trick. I'm thinking my previous failure was the result of trying to edge quench such a large hunk of steel. This time, I tried the less desirable heating the edge only and fully quenching the blade. Worked though.

Just realized you said ATF, and not motor oil. I had in my mind motor oil after I read your post. ATF having lower viscosity than motor oil and my veggie oil. WHY DIDNT I THINK OF THAT!?

 

Thanks Steve :)

They have Parks listed under salt baths. I don't remember if they had Parks listed under oil when I ordered from them a year or so ago but they did have it. At any rate I orderd their Duratherm G and it has been working fine for my uses. I think I paid around $80 with shipping.
