Application Of Tungsten in Modern Weapons

As early as 1781, a Swedish chemist named Scheler discovered the existence of tungsten. When the time came to 1900, the tungsten filament lamp was officially unveiled for the first time at the Paris World Exposition. In the application of tungsten, we not only enjoy the convenience and efficiency brought by the progress of science and technology, but also effectively improve the utilization rate of resources.

However, in the military field, more and more difficult-to-machine materials will appear with the alloying of weapon structural materials. At the same time, people have to further increase the cutting speed. This is how to do? Who can take on this responsibility? - Tungsten. Researchers have produced a cutting tool material that will not soften even if the cutting speed is as high as 2000m/min or more and the temperature of the tool tip reaches 1000℃ - a cermet hardness alloy with tungsten carbide as the main component.

Tungsten-containing structural steel, a kind of steel with only about 1% tungsten, but has a very significant improvement in the performance of the steel. So, what is the most widely used steel type for modern weapons? ——One of them is tungsten-containing structural steel. For example, 18CrZNi4WA steel with excellent mechanical properties and great hardenability is widely used in the manufacture of heavy-duty abrasive parts on aero-engines and high-speed diesel engines. For another example, the gun steel PCrW and PCrNIW, which can effectively overcome its tempering brittleness tendency and improve the strength and hardenability of the steel, are specially used to manufacture large-caliber thick-walled artillery barrels.
