Bluing a Stainless barrel

Comments

    Does anyone know a gunsmith that can reblue a pre 64 Winchester model 70, stainless steel barrel? The barrel is scratched up and looks bad. I have been told that it is not possible to get a quality rebluing job on a stainless barrel. Has anybody had experience with this?

    Corrosion resistant materials like stainless don't blue. You could have the outside plated. I am fond of deep black from rainy nickel.

    It is possible to blacken stainless steel.

    There must be others, Brownells and Dulite sell the chemicals.

    Or you could ceracote or nitron coat it.

    Bluing is a sort of controlled rust, the iron in the steel is converted into the black version of Ferric oxide, similar to magnetite.

    Yes, stainless steel can be blued, but conventional bluing processes don't work well, and even when done the results usually aren't quite as dark.

    No, I can't specifically recommend a shop that does this, but you can buy the reagents to do it here:

    There are a number of other ways to darken the appearance of stainless to look like conventional bluing. Black nickel plating is one; black chrome another. Both are more durable than traditional bluing, and I'd lean towards these for what you describe.

    You say you don't want a "spray on", but the modern epoxy (Duracoat) and ceramic (Ceracoat) based finishes are actually quite durable, and when applied correctly probably every bit as durable as conventional bluing. I wouldn't reject these out of hand either.
