High Speed Steels

The development of high-speed steels begins with Mushet's 1860 product obtained through Hardening of tungsten-manganese steel. The machinability possibilities of these steels were not fully evaluated until 1900, when Taylor and White gave the good news of high speed steel.

High speed steels are materials that have the ability to remove chips even at high cutting speeds and can maintain their hardness at high temperatures for a long time. In order to gain these properties, it is necessary to add alloying elements in appropriate proportions and to provide appropriate heat treatment conditions.

Expected Features

  • Clean and homogeneous microstructure
  • High hardness to be gained by heat treatment
  • high toughness
  • Very high abrasion resistance
  • Resistance to high temperatures at high cutting speeds
  • Suitable for wire erosion cutting, welding, PVD and CVD coating
