Need help with finishes on C96

Surely, I will experiment on scrap steel first.

But there is a strength problem -- does this 570F - 670F temperature anneal the steel?

Alvin,
can you explain exactly what you bought as "nitre" blue salt and how it is to be used?

I have a lot of experience with hot salt bluing and it is not something you will want to do in the kitchen.

Yes, anytime you heat metal it "anneals" it, but the temperature you will reach in hot salt bluing will not significantly affect the "strength".

Annealing will remove any stresses built up from machining, forging and forming steel. Your part has already likely experienced those temperatures.
