and Co. These steels are mainly used for cutting tools

and trace amounts of carbon

but to the method of manufacture. The liquid steel melt is atomized by means of nitrogen. The powder is then hot isostatically pressed (so-called HIP process) and then brought into the respective shape by forging and rolling as in conventional steel production. The advantages of steel result from the more uniform and finer carbide distribution (carbide = hard materials in steel). This makes the material easier to machine. In application

Cobalt steel is a type of high-speed alloy steel used primarily for cutting tools. Introduced to manufacturers in 1900

containing a mixture of tungsten

enabled manufacturers to double or even triple their production.

High speed steels (often abbreviated HSS) are ferrous based alloys of the Fe–C–X multicomponent system where X represents a group of alloying elements comprising mainly Cr

high-speed steel

however

it is still wear-resistant and has a high hot hardness.

since they are characterized by their capacity to retain a high level of hardness while cutting metals at high speed. Generally

The abbreviation PM in HSS-PM does not refer to the alloying constituents of the high speed steel

the X component is present in excess of 7%
