Shooting or reloading somewhere.
Can anyone tell me what the exact composition the P226 Barrels are made out of? What kind of steel? The alloy percentages.

I was wondering why are they not chrome plated like most service pistols like the Beretta?

Does the content of the steel already have anti corrosion properties sufficient for a service pistol?

From SIG website:
SIG SAUER® factory replacement pistol barrels are precision hammer forged to insure accuracy and barrel life. Each is specially heat-treated for toughness and durability.

If you can afford the ammunition required to wear out SIG barrel you can probably afford a new one :)

Nice of you to contribute but....still looking for the an answer to the original question. Yes, I've been to the Sig website, and saw the same statement.

The material of the barrel, and info on why sig's are not plating their barrels.

I'm not trying to be a dink but Glock and Hk don't plate their barrels and they hold up perfectly fine. Chrome lining is more of an American thing it seems. As far as I know, all of the original Hks, G3, MP5, etc. didn't have plated bores.

Who chrome lines a 9mm pistol barrel?

I don't know what the material is, but whatever it is, they are exceptional quality barrels. Mine has ~10k through it (very rough estimate) and I'm starting to get a pretty large velocity span however it still groups very well. I've put two sets of springs into it since I bought it used.

Again.....why is this important.

M&P's ,Glocks, HK's all high quality firearms with no Chrome Plating. I think you might have a hard time finding info on why a company decides not to do something.
 
Steel. Carbon steel. Some of them are, but unless you're hunting giant squid with a pistol, why bother? Not all Berettas are, either.
 
They don't chrome them as its not required and would ad an extra manufacturing step and cost to an all ready higher quality and cost barrel.
 
A lot of companies consider their steel recipe proprietary and will not tell you their exact composition
 
Chrome lining is nice for shooting corrosive ammo, or for full auto firing. Don't see much benefit for using it otherwise. Pretty pointless in a pistol barrel IMHO.
 
chrome lining is a thiing of the past, much better things out on the market today.
sig is useing what most do 4350 steel and some kind of proprietary finish thats is much like what glock and many others are useing.
Glock uses whats called Tenfier, others are useing Melinite, we uses what we call Controled gas nitride , with teflon.
some use salt bath nitride.
No ones useing chrome lineing anymore,, if they are they are living in the past.
A good finish like on listed above will be harded then chrome lineing but with out all the issues that plating has.

Believe the Sig P226 mk25 has a chrome lined barrel, offering more corrosion resistance(salt air applications, I guess).

After the fiasco with the original non-chrome plated M16 barrels in Vietnam (Colt assured the military the the alloy was corrosion resistant and didn't need chrome plating, which turned out to be false), the U.S. insists on chrome plating everything. If HK or Glock are ever adopted by the U.S., they will probably be chrome-plated too.
