Tungsten steel is an alloy of Tungsten and a small quantity of steel with great hardness and good stability at high temperatures. It is one of the most important high-speed steels. Compared with Tungsten carbide, Tungsten steel has better flexibility. Tungsten-steel alloys are widely used for the manufacture of high-speed cutting tools such as taps, dies, twist drills, reamers, saw blades as well as rocket engine nozzles.
