Re: Melonite on SS Action?

I am having a new BAT done now. My reason corrosion resistance. I live in the humid south. If you forget to wipe a BAT bolt down after every time you use it, it will start to pit and corrode. My previous rifle was a surgeon. It was cerakoted. The coating wore off at the rear of the bolt. It was fairly rust proof but not completely. BAT says the melonite will prevent the corrosion, make the action smoother (they are extremely smooth to start with), and virtually eliminate a galling issue. Hope this helps, just my $0.02

That's some good advice, makes me think even more

I don't think you will get a general consensus that an action is more corrosion resistant after that treatment.

A consensus from people who have done it? From what I understand, this treatment is basically corrosion proof and bullet proof. I admit that I haven't done it yet but I'll find out soon.

My reasons for doing it,

-Corrosion resistance, best available to my knowledge
-Most durable finish available with a hardness factor of about 65 - you can't scratch it with a knife
-Appearance, to match my barrel - the H&M process can be finished to a satin or matte black which would look very much like a rifle I had parkerized years ago.
-Silky smooth action

And finally cost. It's going to cost me $200 plus shipping plus my smiths fees for disassembling and reassembling to have 3 rifles done for what amounts to a life time finish.

And if you don't like the black finish you can paint or ceracote it.

No, most of those people will believe whaterer they are told.

If you research Engineering studies, I think you will find that salt bath nitriding likely improves the corrosion resistance of carbon steel and decreases the corrosion resistance of stainless steel.

Here is what H&M is claiming based on salt spray and field immersion tests.

Re: Melonite on SS Action?

I've read from one company rep that it may decrease the corrosion resistance of stainless steel - infinitesimally less. Stainless steel appears to come in different grades, with respect to its corrosion resistance. Some stainless will show more reddish rust than others over time. My brother has had a gunsmithing/gunshop business for 30+ years here in Alaska and sees rifles, shotguns, and pistols coming in from many areas of the State. Many are exposed to ocean saltwater environments. He sees variable corrosion on stainless guns based on the differing manufacturers.

The melonite coating if VERY corrosion resistant on both stainless and non-stainless steel. BAT wouldn't be treating their stainless actions if doing so meant they rusted with abandon after doing so. I think the worry about any corrosion impacts to stainless steel are relatively meaningless, other than for academic purposes.

Here's one thing about melonite. How many other coatings are available that treat the rifle bore itself? The part of the barrel that could really affect accuracy should it corrode.

All I've been reading about melonite treatment is positive, and I intend to have all my future new barrels melonite treated - until I hear a reason not to. Especially any chrome-moly barrels. I have one CM barrel in for treatment now. As MontanaRifleman stated, a person can always Cerakote after the melonite treatment if desiring a different color.
