What barrels(brand Steel)are set on standard brands Savage 111G 300WM.
Thank you for an answer.
I have no idea what brand, but, I am certain it is Certified Ordanance Grade. Made in the U.S.A. (would you want to trust steel made in a third world country in court?). Anybody that makes receivers/actions, barrels, or bolts (the stuff that handles the pressure) has a file cabinet full of certificates and receipts for the raw materials they have purchased and used. It's all about liability.
At every alloy steel or Certified Ordanance Grade there is EXACT the NAMES and marking.
Certified Ordanance Grade it is the not name steel,it is very important to know composition Mo,Cr,Si,S,P,Mn,C-these indexes influence on longevity of barrel and on his TTD.
Example the breech-block group of Mauser is executed from steel 8620.
I am sure on 100%, that analogical barrel of rifle MarlinXL7 30-06 is made out of steel 4140,barrels MarlinXL7 30-06(22",1:10) and Savage 111G 300WM.(24",1:10) similar,-however on the site of Savage there is not exact information about a producer steel.
Thank you for an answer.
I got info at the shot show about 25 years ago that ER Shaw made the savage barrels at that time. May or may not have been true and that was a long time ago. You hear a lot of diversion tactics at the shot show but it came from more than one good scource.
I would divide all of information into OBJECTIVE and SUBJECTIVE .
Information about the brand of steel is OBJECTIVE.
I can assume,that a barrel is made from Steel(42CrMo4)4140-BUT exactness will not prevent.
Thank you for an answer,
Good luck getting an answer from Savage! (the people you should really be directing this question to)
I can not get E-mail Savage Arms.
Sorry, Savage is the only one who would know for sure what the A.I.S.I. number of the steel (what grade) they use in their barrels is, and, what the properties are after heat treatment. Anything else would just be second hand info or a guess. Manufactures don't usually give out such info, instead they may give a 'specification' number. It is an engineering 'specification'.
I now stand before the choice of rifle of Savage 111g 300wm.
Foremost I am interested by the resource of barrel and possibility of the extreme use
+50С degrees Celsius- -75С degrees Celsius, water, snow et cetera.
Knowing the brand of steel it is possible to say with certain exactness, that expects this rifle in the future.
Thank you for an answer.
I am in Military Aerospace------foreign sources are standard and even required in some instances so that dog will not hunt.
Sure, there's some, most likely more than I realize, that comes from over seas. I think the key words here are Third World. It takes some know how and technology to manufacture those 'higher end' steels, or at least, it used to 20 years ago when I was in manufacturing. And we have that ISO tracking. Still, I cannot see any barrel maker giving much more info than "Ordnance grade Chrome Moly or 416 S.S". Just another thread about barrel life!
Savage for making of barrels Savage 111G 300WM. steel is used Jorgenson 4140.
Jorgenson Steel 4140.

Normalized Bars - Ends painted Gray
Annealed Bars - Ends painted Brown
This chromium molybdenum alloy is a deep hardening steel used where strength
and impact toughness are required. It has high fatigue strength making it suitable
for critical stressed applications at normal as well as elevated temperatures. For
increased resistance to wear and abrasion, it may be nitrided.
This grade is a quality product melted under the best of steelmaking practices for
aircraft quality steels. It is vacuum degassed to meet the magnetic particle inspection
standards of AMS 2301.

APPlicAtionS - Intended for general use for parts with sections 1/2" or less in
thickness at time of heat treatment which require a through-hardening steel capable
of developing hardness as high as Rockwell "C" 50; also for fittings and forgings of
greater hardness or variation in thickness at proportionately lower hardness. It is frequently used in applications in which 8640 is specified.
HArdenABility - End-quench hardenability values for this grade are Rockwell
"C" 50 minimum at 6/16" and Rockwell "C" 44 minimum at 9/16".

I am surprised!
Just so everyone knows ---Jorgenson is a distributer not a manufacturer who sources from all over the world.
From thier website:
"Our global supplier base, combined with our tremendous purchasing power, assures our customers that we'll have the metals they need, at the most competitive costs and fully conforming to their quality specifications."
Bottom line if it meets spec it meets spec.
