Thread: Nitriding

Anyone here ever nitrided (i.e salt bath nitriding or plasma nitriding) their firearms? And who can do it in NZ?

I've noticed that Mauser and Rigby are now nitriding some of their high-end guns. While it looks like blueing (black-ish in colour), it's not a finish, but rather a surface hardening treatment which changes the structure of the steel itself. Much more durable and corrosion proof than stainless as well.

I came across these guys online. NZ company. Not sure if they'd work on firearms? Heat Treatments Ltd - heat-treating and surface finishing services for metals and alloys

If any of those metal treating processes could be applied to guns, why would you stick with regular blueing or plain stainless?
