Stainless vs. chrome moly steel

[IntelGDR691]

Little question for you guys,

Is there any difference between the two in matter of resistance and durability. Wich one make the stronger action and/or barrel. I know that s/s by definition is more corrosion resistant but as general toughness, wich one is better???

Thanks

I tried doing a search that would post some pro's & con's of either... It is from the internet so take it with a grain of salt

As far as actions and barrels go, I believe chrome moly is stronger and stainless barrels last longer.

The gentleman in your link is right on the money, making gun barrels and receivers from free machining type 416 stainless only benefits the gun makers.

I prefer stainless barrels as they do machine better and are easier on tools. The only other advantages I see is that due to the smoother interior, they tend to shoot better, at least the cut rifled barrels do and there is not the need to spend further money having the barrel blued or treated to prevent rusting.
Stainless does oxidize however, it is just not as noticeable as brown rust on a blued or silver barrel.

and for the action, is there an advantage other than rust resistance???

Stainless actions are weaker and gall easier.

416 type stainless is not a galling type of stainless steel.
Type 410 stainless, (properly heat-treated), would equal 4140 or 4130 alloy in strength and durability, but much more expensive to produce. Barrels made from 416 and left in the unhardened condition cannot possibly last as long as barrels made from chromium-molybdenum steels.

check out this article... pretty intresting facts...
if any other comment, especially for action materials...

thanks guys
