Hi.
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.
P.S.
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.
Kristian.
