Steel, an alloy of iron and carbon, there are many varieties. Mixed with other metals, need to be in different properties. Tungsten is the first metal used to improve steel. It increases the strength of steel over a wide temperature range.
Value of alloys
Metals are known as mixed alloys with new properties. Mixing and a small amount of other metals such as vanadium, tungsten and cobalt contribute to strength, hardness and corrosion resistance.
Properties of tungsten
For the same, is a basic chemical element. It can withstand heat more than any other metal, with the highest melting point, 6192 degrees Fahrenheit (3695 degrees Celsius), the highest tensile strength of more than 3000 F (1650 C). It also does not extend to other pure metals at high temperature and high resistance to corrosion.
Application program
Cutting tools, such as drill bits, friction to produce tremendous heat. The number of tungsten, added to steel ranges from 2 to 18% (with a small amount of Mu Hefan), maintains the high temperature strength of the metal. Known as high-speed steel, it enters bits, milling cutters, saw blades and other tools.
