M-2 is a tungsten-molybdenum high-speed steel. It is a popular grade for cutting and non-cutting applications. Compared to M1 Tool Steel, M2 grade has a high carbon content which provides higher wear resistance for applications that need it. M2 High Speed Steel has a wider heat-treating range than most of the molybdenum high-speed steels.
Reloading Molybdenum Disulfide. $ 10.95. The idea and theory behind moly coated bullets is less work on the barrel, less barrel fouling, longer barrel life, and more accurate shooting. Moly coated bullets have been around for a long time now. Molybdenum disulfide is a very "slippery" product with great lube properties at both high heat and ...
A popular example and perennial favorite in the U.S. is called SAE 4140 chrome-molybdenum or "chrome-moly" steel. In Europe, vanadium and nickel-steel alloys are preferred. Most standard barrels …
gun barrels than ordinary "hard" chro-mium, and, secondly, to improve the performance of the caliber .50 machine-gun barrel. The program was later ex-tended to barrels of other calibers. The search for a bore coating bet-ter than hard chromium was not suc-cessful. Materials with somewhat im-proved properties in specific barrels
On 13 March 2012, the United States requested consultations with China with respect to China's restrictions on the export of various forms of rare earths, tungsten and molybdenum. The request refers to materials falling under but not limited to 212 eight-digit Chinese Customs Commodity Codes and over 30 measures.

Barrels Lined with Stellite 25 . by William S de Rosset and Sean Fudger . ... Biodur is a cobalt-chromium-molybdenum alloy made by Carpenter Technology, Reading, Pennsylvania. ... The liner has been sprayed with a thin layer of tungsten carbide particles. Subsequent machining produces the final dimensions. In the case of the tubes made for …
Molybdenum disulfide MS2, tungsten disulfide WS2, hexagonal boron nitride HBN, and Lubalox are common bullet coatings that purportedly reduce friction between the bullet and rifle barrel. Three different bullets, one a solid copper design, and two jacketed lead bullet designs, were tested in the 5.56 mm NATO rifle cartridge. After coating, these bullets …
The Challenge of Plating On Molybdenum. Molybdenum is highly beneficial for metal finishing and especially electroplating, which involves applying a protective metal coating onto the surface of another metal, or …

Tungsten's use in the production of military equipment goes back a long way. As far back as 1822, it was used to improve the durability of gun barrels. The steel used to make the barrels were highly susceptible to corrosion from contact with gunpowder. Adding tungsten to the steel improves its durability and ability to resist corrosion.
