ABSTRACT
A range of different grades of steel are used in the manufacture of a single firearm. Chromium-molybdenum steel is the basic material for the modern firearms industry. It possesses good tensile strength, resists wear, and has good machining properties. Most .22” rimfire caliber guns, shotguns, and low pressure centerfire barrels are made from carbon steels. High-pressure centerfire barrels for sporting use are normally made from chromiummolybdenum-vanadium steel.
