and Co. These steels are mainly used for cutting tools

and trace amounts of carbon

as well as in other industrial applications. It consists of fine particles of carbide cemented into a composite by a binder metal. Cemented carbides commonly use tungsten carbide (WC)

Cemented carbides are a class of hard materials used extensively for cutting tools

chromium

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

or tantalum carbide (TaC) as the aggregate. Mentions of "carbide" or "tungsten carbide" in industrial contexts usually refer to these cemented composites. The cobalt content could vary from 5% to 23% base on application. 8% to 12% are the most common for cutting tools. Ruthenium is used to replace cobalt as a perfered binder for the best cutting performance.

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

the X component is present in excess of 7%
