DIY Black oxide on 316?
 

I am trial fitting some sexy black traveler and Genoa tracks on Rutu. I
have the fitting just about perfect but the only thing you see is the
glaring stainless flat head screws. I cannot find 316 stainless 5/16 x 3"
flat head machine screws in black oxide 316. How hard is it to put a
durable black oxide finish on 316 and how do you do it.

I could powder coat them black but that might make the heads stand up a
little and interfere with the precision slides.

By definition of stainless you can't get oxide on it. I've used black
fasteners in the aviation business, but I think they were aluminum anodized.
I want to say that I've seen something in stainless, but for the life of me
I can't remember what it is.

316 Stainless will oxidise but it reduces the corrosion resistance and the
heat required, if done thermally, will soften the bolt. There are chemical
solutions that will do the job if required.

Great link; thanks. It goes in my resource files.

You might also google for black chrome plate. I think that is how
stainless gun barrels are made black.


Dan

Stainless gun barrels are blackened by treating them in a specialized hot
bath made by Brownells called Oxynate 84

Firearms are usually made from 400 series stainless. How it would work on
316 is a question best answered by Brownells tech support.

I just googled on "Black Chrome". It does exist and is used on gun
barrels. Not the only way to get black chrome, but possibly more
durable than other methods.


Dan

Brownells Gunsmithing Supplies has stuff for oxidizing stainless steel

brownells.com IIRC

Since you can powder coat you could just grind a few thou off the screw
heads and then the clearance will not be a problem.

Plan "B" would be just to use a marker and make them black.

About the time I had mastered getting the toothpaste back in the tube, then
they come up with this striped stuff.

I would agree that black chrome would be more wear / galling resistant.
