I am going to try and put a stainless steel guard on a knife made from O1. Will 440c work for the guard steel, 1/8" thick? Do I need to heat treat the guard before I put it on or can it just be used as is since it's just a guard? I was going to use a silver solder from USA knife makers(96% tin, 4% siler) will this be good? Would a nickel silver guard be a better choice? Is it as stain resistant and strong as 440c? Thanks for any help.
 
I'm no expert, but I can't see any reason to HT a steel guard--they don't HT brass guards and that's a heck of a lot softer.

Also, you might consider dispensing with the solder and trying JB Weld--many makers go that way. The guard should be more or less a "perfect" fit anyway and the solder/JB Weld is basically to act as a sealant to keep moister out of the joint.
 
Ask a metallurgist for the details (e.g. Mete) but the issue is not just chromium content
but what sort of structure the chromium is bound in. In as far as I understand it,
chromium that is locked up in carbides does not contribute to stain resistance.
 
Any recommendations for a good stainless steel for a guard? Is 440C good for that or is there a better choice? thanks
