Read bullets below if you just want the info...
All,
When researching Anti-Seize for barrel installation I came across good info and figured I would pass it along so someone else doesn't have to do the same. This was important for me because my install involved a stainless steel barrel and barrel nut on my 110 action. The precision barrel nut instructions from Northland Shooters Supply specifically stated to coat all threads with anti-seize. In all the excitement of my first savage build, I did not apply anti-seize. However, five minutes after the rifle was assembled I realized I had forgotten sumpin...Anywho, I did my research, ordered the $5 Nickel anti-seize, found out it wouldn't arrive until 9 Feb, found aluminum anti-seize at autozone, called the Permatex company for permapermission to use on stainless steel since this particular product wasn't listed on their website, and then came home to find the nickel anti-seize in my mail. Lol so now I figured I would document what I learned and let the brotherhood know for future first-time barrel installers
. My references are Permatex.com, Depacsproducts.net and Nothland Shooters Supply.
- Aluminum/Copper Base and Plain Copper Base:
Anything with copper base is a no-no for stainless. Many people know this and therefor steer very clear of it. I recently found this out with research and that the aluminum/copper base is just as bad in the end game. The copper in aluminum/copper or plain copper base causes a crystalline corrosion reaction with the stainless steel. This will eventually cause the stainless to fracture and brake or crack. Thats why anything with copper base is forbidden in nuclear facilities...
- Aluminum Base:
Aluminum base anti-seize is safe for stainless steel as long as you stay within the temp range of the lubricant. I confirmed this with Permatex technical specialist over the phone when I came across the Aluminum Base Anti-Seize at AutoZone and couldn't find the product on their website. The only drawback to aluminum base anti-seize is that it reacts with carbon steel in a way that the lubricant loses its protective characteristics which then leads to corrosion of the unprotected steel.
- Nickel Base:
Nickle base anti-seize is also safe for use with stainless steel. It is probably the most commonly used anti-seize for stainless steel in industry and has the highest temperature operating range. The Permatex technical specialist said most people use it but they don't have to since aluminum may also be used for this application. The drawback to nickel base anti-seize is that it is a known carcinogen. It can be dangerous in environments where it comes in contact with bare skin...
The three types of anti-seize are shown below (AGS packet has copper base):
hope this helps somebody some day... Shoot on!
