4150 ak barrel, Learn more about it here
4150 ak barrel, Alloy Steel 4150, also sold under the name AISI/SAE 4150, is a high-carbon alloy that includes chromium, manganese, and molybdenum. Higher levels of carbon and chromium make this 4150 alloy steel more wear-resistant than 4820 alloy steel. May 17, 2025 · 4150 steel is classified as a medium-carbon alloy steel, primarily known for its excellent strength, toughness, and wear resistance. 4150 round bar is a higher carbon variation of the chromium, manganese, molybdenum 4100 series of low alloy steels. SAE/AISI 4150 is a chromium-molybdenum alloy steel offering high strength, excellent hardenability, and wear resistance for demanding engineering uses. It is famous for its excellent hardenability, good toughness, and high tensile strength. The addition of sulfur along with calcium treatment in the 4150 alloy steel grade results in improved machinability for many larger part sections. Jul 13, 2023 · 4150 steel is an alloy of carbon, chromium, and molybdenum used for its high tensile and yield strength, hardness, and machinability. Learn more about it here. This makes it perfect for parts that must endure high stress and wear, making it a go-to choice in many demanding industries. Also known as chrome-moly steel, it’s often used for gears, shafts, and ball screws. Jul 25, 2025 · There are a few types of carbon steels used to make barrels, but one type of steel -- advertised as 4150 CMV -- is, by far, the most popular (it's what we use for most of our AR-15 build kits and uppers). The primary alloying elements in 4150 steel are chromium (Cr) and molybdenum (Mo), which enhance its hardenability and strength. Why? It's the "mil-spec" steel that service-issued M4 and M16 barrels are made of. This tough steel alloy offers uniform strength, wear resistance, and great hardness. Alloy > 4150 A modified and re-sulfurized chemistry of this medium carbon alloy steel grade provides a more thorough hardenability. For added wear resistance, it can be surface hardened with heat treating. Alro stocks 4150 steel - a part of the SAE (Society of Automotive Engineers) family of steel grades. Jul 13, 2023 · 4150 steel is an alloy of carbon, chromium, and molybdenum used for its high tensile and yield strength, hardness, and machinability. . Sep 27, 2025 · AISI 4150 is a high-strength chromium-molybdenum alloy steel. This page is mainly introduced the AISI 4150 Datasheet, including chemical information,mechanical properties, physical properties, mechanical properties, heat treatment, and Micro structure, etc.
