Steels containing tungsten, such as high-speed steel and some hot work die steel, steel containing Kekai tungsten bar steel hardness and heat resistance have very significant increase, but the toughness will be a sharp decline. The main components of carbide carbide and cobalt, which accounted for 99% of all the ingredients, one percent for other metals, also known as the yo tungsten steel. The main application of tungsten boat carbide resources also, which is tungsten steel. Carbide, known as the modern dental industry, the extent of the use of Gang products is very wide. Tungsten steel sintering the powder is pressed into the blank, and then into the sintering furnace heated to a certain temperature (sintering temperature), and maintain a certain period of time (holding time), and then cooled down to obtain the desired properties of tungsten steel.
