    Is the Beretta Graystone finish commercially available? Is there another name for the process? Sure would like to have this done to rifles and handguns. That stuff wears like iron!!

    There were some past threads on this subject and I did a quick search for them, sorry, no luck. As I recall, the graystone finish cannot be duplicated outside of the factory. Bill Malcolm

    The stuff Tony DeSimone is using is less silvery. I'd say it's somewhere between nitrite and greystone.

    I believe it is a nitriding of some sort. I've been trying to read up on a lot of the latest nitriding process. I believe Krieghoff is now using a nitriding for there engraved recievers. The process they may be using is to give the "French gray" look, but with the durability of the nitriding.

    Some process are producing several different colors depending on the gases used. The black and gray seems to be getting some traction with the racing world.

    I'll be researching this more.

    I just had 2 BT-100 receivers plated by Tetra Tech in Anahein with their hard chrome finnish. It is a matt silver, very hard, wears like iron. I believe it is approximately a Rockwell "c" 72. They do have a webb site. Bob Knight

    Thanx for the responses- checked into them and they are close but no match. I want the exact equivilant of the Beretta finish. This is one of the best kept secrets of all time. There has to be a commercial application somewhere somehow. I can't believe that the only ones in the world to use this process is Beretta. This stuff is bulletproof. Somebody somewhere along the line must have unlocked this secret. thanx for your input! TG

    If my memory serves me correctly Beretta called it a coating not plating.

    It is a nitriding process. I think another term that's used is plasma coating. The material that is being applied, is applied at the molecular level.

    Nitriding is a term I use to refer to the coin finish on some fine older guns. This is achieved with diluted nitric acid.

    The so called "plasma" coating process has been around for a long time. Sinks and some pans have been enamel coated by spraying them with fine glass beads and then melting the glass into a smooth film in a furnace.

    You can coat a gun receiver with small granules of a hard metal and then melt the metal to form a coat over the receiver. The theory is simple. But, to do it correctly, you better know a lot about hardening metal and have your furnace set to the correct temperature. I do know enough about heat treating metal to know that I don't know enough to try it.

    Check out EABCO.COM - They have a finish called "French Gray" that looks great and it's really tough!

    I believe Arthurs is usinga plating process....and highly likely it's a chrome plate. With the beaded surface, chrome gives you a "gray-ish" color.
