Is it worth the extra time and trouble to heat treat 416 stainless for increased corosion resistance? I'm working on some folders which will have 416 stainless frames and I'd like to get some opinions from others who have experience with this material. Also,what is the best heat treating recipe?
Thanks in advance.

I am no where near the experienced knifemaker Don is. And I am not trying to start a disagrement. But I heard that 416 is not "stainless" until it is hardened. Temps I was given were 1800 degrees to harden and I think 1200 degrees to temper. It will still drill and mill fine but will be stainless now. I was also told that if you spotweld the bolster on the liner and you don't harden the bolster you will have little circles show up on the finished bolster where the weld is because the weld "spot hardens" the metal.

As for the liners I don't think they are heat treated but that is because the thin liner turns into a "potatoe" chip very easily.

I've sold many, many hunting knives with 416 bolsters or guards and never ever had a problem with rusting without having to heat treat. Frank.
 
Thanks to all for your replies. You've saved me a bunch of time.
