HSS Material

High Speed Steels

  • Production:Normally it is made by using electric furnace, recently it has been produced by powder metallurgy for high speed steel, which makes a very fine carbide particles uniformly distributed. On the substrate, the material life is prolonged.
  • Application:Being material of various cutting tools, cutter, drill, hob, saw blade, and high-end mold.

It is also named as wind steel or sharp steel, which means it can be hardened in air and sharp in quenching. A kind of complex alloy containing tungsten, molybdenum, chromium, vanadium, cobalt and carbide forming component .. which total elements content is 10~ 25% .. It may still maintain quite high hardness during high speed machining that caused high temperature (about 500 Centigrade) surrounding. The major benefit of high speed steel is its HRC above 60—Red Hardness.For carbon tool steel, after quenching and low temperature backfire , it remains high hardness under room temperature. However, the hardness will be reduced speedily when it is over 200 Centigrade and the hardness will be reduced into the same situation of backfire if the temperature up to 500 Centigrade, which already lost its ability of cutting metal. That is not suitable to produce cutting tool. High speed Steel is with good red hardness which may make up for the weakness of carbon tool steel so it can be used in manufacturing cutting tool.
