Oct 16, 2012 · Chrome, molybdenum, and vanadium are impurities added to steel to give it corrosion resistance and other properties. 'Chrome moly vanadium' is almost certainly to do with the steel the barrel is made of, while a "chrome lined" barrel is, well, lined with chrome for high wear and corrosion resistance in the bore and chamber.

Nov 21, 2005 · ORD4150, ORD4150-Resulferized, and Chrome-Moly-Vanadium (CMV) should not be confused with the generic term of a Chrome Moly barrel. My opinion and the opinion of the US Government (as defined by the Mil-Spec) is that one of the three is not better than the others. They are all they same and are all 11595 (Mil-Spec) barrel steel.

Nov 19, 2011 · In simpler terms Chrome Moly equals Chromium Molybdenum. This is what most barrels that are not made from stainless steel are made of. It would be much easier to understand if people would use the term "Lined" vs "Non Lined" barrels rather than Chrome Moly vs Chrome Lined. The barrel is made from the same material. As has been explained.

Aug 3, 2024 · Yes, we offer Chrome Moly (C.M. 4140) steel, Stainless Steel (S.S. 416R) as well as Mod400 a Bartlein Barrel exclusive. Which steel is better? Each type of steel has strengths and weaknesses. -C.M. must be used for some of the lighter contours of barrels. C.M is also needed for customers wanting to "blue" the steel.

Apr 14, 2020 · Stainless doesnt need to be coated and chrome moly does to prevent rust. So instead of paying extra for coating on something that's going to need to be replaced, they just used stainless barrels. I think any good barrel maker can make an accurate barrel out of either. I have a chrome moly shilen and have no complaints.

Jul 17, 2003 · The stainless alloy(s) used for rifle barrels have good (not perfect) resistance to corrosion and are easier to machine than "chrome-moly" steel.The chrome-moly steel barrels have been around for some time and barrel makers are very experienced in using this alloy. Either alloy will make a barrel that will exceed your abilities to use it.

Dec 31, 2009 · Chrome moly barrels - unlined - generally do not have a 50,000 round service life, especially if you use accuracy standards to determine when a barrel is unserviceable. Chrome lined, chrome moly barrels have anywhere from 3 to 10 times the service life, according to military tests with machine gun barrels.

Feb 7, 2006 · The only difference we find is that sometimes the chrome moly might take a little longer to break-in and might have a little more affinity for copper or seems to show it easier. In terms of barrel life and accuracy, we can find no difference.”--LongRangeHunting.com (Dated: 10/2004) Searched for: “chrome moly or stainless steel”)

Feb 6, 2013 · Re: Chrome Moly Steel or Stainless steel Barrel Are you replacing a bolt action or gas rifle? Chrome Molly I believe is fairly common on AR's and the like. As I understand, the following trade off longevity~accuracy: Chrome Lined: Longest lasting/ process more likely to effect accuracy (less maintenance)

Aug 21, 2010 · This is enough time and temperature to harden chrome-moly-vanadium steels. The martensitic steels (400) are much more resistant to this but will still gas erode. For match work in the 5.56/.223 Rem, this is about 5000 rounds for 416R.
