Does chrome moly last longer than stainless?

The adi reloading guide gives pressures from 45,000- 60,000 psi for popular centrefire rounds, of course using trail boss for making centrefires subsonic drops the pressure to around 25-27,000 psi.

40,000 psi is 275 Mpa which is the tensile yield strength of 416 stainless, the yield strength is where it starts to go through inelastic deformation before it fails which is the ultimate tensile strength which is 515 Mpa for 416 SS.

Chrome moly has a yield strength of 435 Mpa and a UTS of 670 mpa, if your loads are less than 63,000 psi according to the adi book you are below the yield strength of 4130.

I would go chrome moly over stainless on the fact chrome moly would be below its yield strength for the maximum pressure loads in the adi book with stainless being above the yield strength on start loads.
The saving factor here is these pressures are only sustained for a tiny fraction of a second.
Stainless can handle heat a little better than 4130 which like pressure is not sustained for great durations.

A colour heat chart will show black is the hottest colour for things left in the sun, perhaps stainless has an advantage in cooling when walking around in the sun as it will not absorb heat like a black barrel.

Perhaps the accurate lifetime of a gun is much shorter than its lifetime it could fire,i reckon a 22lr would win this one.

One of the guys here reckoned he was up to about 20,000 shots with his 22LR without ever cleaning.

The suckers last forever.

Sounds like my grandfathers axe...it's had twelve new handles and thee new heads! :lol:

modern pistols should last almost forever

Not likely to maintain acceptable accuracy beyond 10 000 to 15000 rounds for an auto centre fire even with a chrome lined barrel . A lot depends on how well the throat stays intake . If the chrome starts to peel off at the throat as it erodes then it wears quickly after that . A real high quality chrome barrel might see 20 000 useful rounds but I doubt it because of fire cracking just in front of the chamber . Standard Military weapons can be used for longer as the standard of accuracy required in combat is less in general than most target shoots or hunters would require .

It's a bit like asking how long is a piece of string? there are so many variables even within the one calibre to really quantify. How loads, bad cleaning, all sorts of thing will shorted life of a barrel. Some times the crown or the throat gets buggered before anything else. Then there's the great unknown; the rifle that will still shoot well until it's almost a smoothbore!

i got a good laugh out of that ..... :lol:

the only reason i put a 223r barrel on the rem was it's groups opened up to .75moa min and as it was my work rifle (culling roos) i went 223

Most actions if looked after well will outlast several new barrels .

A cared for .22 could outlast you and your kids.
