Stainless steel galling and lube question

Hi
Does stainless steel need to be lubed by a special lube to prevent galling? Will Tetra Gun grease or lube be suffice for stainless steel parts? And what exactly is galling?

I've been using RIG +P Stainless grease for years on blue and stainless guns with fine results. According to RIG, it was formulated specifically to prevent galling on stainless firearms.
 
I know first-hand that Mil-Comm Products' TW-25B lubricant protectant prevents galling, as well as every other good property you are looking for. bestdefense.com has it
 
Stainless galling

Galling is basically the material welding together under the right combinations of pressure, friction, and temperature. Certain types of stainless when used together are particularly good at it. Type 304 stainless when used against itself will gall very easily. To prevent this, if you are using a fastener in 304, then get a fastener made out of 'Nitronic 60' (UNS S21800), commercially available and a little pricey. Or you could get them in '17-4 PH', even more pricey.

As for lubricant, a couple that haven't been mentioned are 'Neo-lube' and 'Never Seez', both excellent stainless lubricants, though I don't know how they would be for firearms.

Hope this helps.
 
Thanks. That answered it.
Are stainless guns made of 304 stainless? How do you know so much about metals? I'd always wanted to learn about technical metal stuff like that but just don't where to start.
 
I use lubriplate.Used it on a AMT and then on all my guns.No galling and no problems.Plus its only 3 and change for a big tube at your local parts store.Will last you years.
 
I am not a specialist in metals, but it is my understanding that the firearms manufactor normally uses two different types of SS to pevent galling. It has something to do with the different metal formulas wont interact and gall. I also use Lubiplate, a little goes a long way and lasts a long time, I lube machinery with Lubriplate that might not see another service man for years.
