in the land of Scrolls,
depends on which alloy but there are salts to hotblue stainless metals. I don't know any details, just know that it is done on certian alloys.

Marcus, a gunsmith friend of mine does stainless blackening. It looks just like the hot caustic bluing found on many guns. 410 works well but it has to be bead blasted to work. For some reason, the chemicals don't have the same effect when the item has been polished. That's all I know at this point. David

Marcus,
I've done a fair amount of hot bluing over the years. I also called Doug Turnbull to verify my experience. There is a blackening process for stainless, but it's done on a commercial basis. As for the typical gun shop. Chances are near non existent.
Good Luck.:(

Marcus if you just want to blacken the engraving Silver Black works some what on some stainless. It's sold in the jewelry tool suply catalogs and made by Griffith. It has hyrochloric acid in it. I beleive if full coverage is wanted it can be annodized, but that is a commercial process. It also can be plated with almost anything after a nickel strike plating is applied.

Be cautious when using anything with hydrocloric acid around stainless. Hydracloric acid takes the chrome into solution so etching of an engraved surface could be a little frustrating.:(

coloring stainless

Look to Brownell's gunsmith supply catalog for blueing blackening info, they have a tech dept that is staffed with men who can help answer your questions, I am almost positive that you will not blue-blacken 300 series s/s but any of the carbon bearing s/s can be colored to some extent. Thanks for listening. Jack Davenport.
