Thread: Bluing stainless

Has anyone tried this? Or do you have to ceracote etc

@257weatherby has a coating that LOOKS just about like blueing .....pretty sure its a paint of some sort,looks great.

If this link works ?
There's a well tried and used product that has been around for a while
Blackens ss matt to semi gloss depending on the prep and texture wanted

I'm keen to try it
But it's a hazardous material and they won't freight internationally
I'm sure a chemist could point me at a recipe
But the need hasn't been enormous so it keeps slipping down the list

Try this !

ok thought about dye as well

Way back some time, when Remington were starting in to making 700's for magnum cartridges, they believed that chrome moly barrels wouldn't last as long as stainless. Apparently they "iron oxided" stainless barrels and blued the iron oxide. Tried to reblue my original 7mm mag barrel, cleaned down the barrel, and then gunsmith told me after the bluing bath he was able to wipe the blueing off. Left the barrel clean and never had a problem.

Just out of interest, there is a supply house for such chemicals in WI and the composition of their low and high temperature bluing solutions for stainless can be found listed in the MSDS for each. Here are links to their web pages on the two products:

The high-temperature black appears to be a concentrated hydroxide solution similar to that used for bluing non-stainless steel rifle parts, and runs a similar risk of steam explosions and caustic burns for the unwary. It looks like the similarities extend to the necessity of running acid and rinsing baths to prepare the metal surfaces. I'd be inclined to try the low-temp mix first, though seldom with these things are the low temperature results comparable.

looks like duracote might be easier dont really like my silver firearms hate chrome on engines...
