Blacken stainless steel

[travis223]

Blacken stainless steel through the use of oxidizing type blacking compounds. This process produces black coatings on stainless steel and alloy steels by a "conversion" process. The chrome in the stainless steel is involved in a chemical reaction with the oxidizers in the solution producing chrome-sulfide. The application of the black finish is dependent upon the surface treatment of the steel. Bead blasted surfaces will have a satin black appearance while a surface blasted with aluminum oxide will be matte in nature. Importantly, dimensional changes involved in blackening are extremely small, less than 0.0001 Mil. This thickness of the black oxide type coating ranges from 0.00006-0.0001 Mil depending on the type of alloy being treated. I was just wondering if anyone hear has any knowledge as to where to send a barrel for this process or do any of the venders offer this.

I was going to suggest Robar, but I think your post is directly from their web site, so you must know about them...

Yes I know of them was wondering if any of the vendors were closer for example sss is lot closer to me than Arizona. I also hoped to find someone who has had it done to there barrel to see if they liked it ..Ty.

Salt bath nitriding will turn it black. Also known as Melonite, Tennifer, and a few other names.

OP, I had a barrel done by Trutec/MMI, I would think you would be very happy with this, but not quite the same process as you are describing.
