Tool AND Alloy Steel

For mordern industrial production, particularly mass production, machining is one of the most important shaping and forming processes. Almost all tools employed for this purpose are made from high speed steels.
In recent times, the use of high speed steels has also gained increasing importance for chipless shaping, eg. for extrusion, blanking and punching tools.
With regard to chemical composition, distinction made between W-, Mo- and W-Mo alloyed steel grades which, depending on the dominant stress they will be exposed to contain different amounts of carbon, vanadium and cobalt.

1. The characteristic properties of all high speed steel grades includes:-

2. High working hardness

3. High wear resistance

4. High retention of hardness and red hardness

5. Excellent toughness
