Chrome Moly Vs Stainless Steel

A popular example and perennial favorite in the u s.

Chrome moly vs stainless steel.

Chromium molybdenum specifically means a family of steel alloys that when used for hand tools have a moderate amount of carbon often around 0 4 to 0 5 around 1 chromium around 0 15 to 0 20 molybdenum and a range of other alloying elements. The common grades of alloy steel have a skooch less than 1 chrome which is way more than is needed to ensure something as skinny as a rifle barrel achieves hardness to the core. With today s typical 1 9 twist rate a conventional steel barrel should last about 3 000 rounds a chrome moly steel alloy should last about 5 000 rounds. The name given by the society of automotive engineers sae usually follows the pattern 4xxx.

Does stainless affect the rifling quality or the life of the barrel. The primary purpose of the chrome is to increase depth of heat treatment for a given severity of quench. Is called sae 4140 chrome molybdenum or chrome moly steel. Chrome moly vs chrome vanadium is a wash.

41xx steel is a family of sae steel grades as specified by the society of automotive engineers sae. In europe vanadium and nickel steel alloys are preferred. Stainless steels stainless steel barrels have been around since. Ik that stainless has better longjevity in the finish but if you were to paint it would it be a waste of money to get the stainless.

The stainless spindles are solid 17 4 alloy and will not corrode. A stainless steel barrel should last at least 7 500 rounds and a high quality chrome lined barrel should last at least 10 000 rounds. The weight difference between our zero stainless and chrome moly pedals is insignificant unless you look at it on a gram scale. While the chrome moly spindles are anodized the finish is subject to wear.

The inherent difference is corrosion resistance.
