Heat treating is an essential phenomenon that is very much needed to manipulate the physical, as well as sometimes the chemical properties of a metal. Heat Treatment of ferrous alloys, involves heating and quenching of the related material at extreme temperatures to get the desired result, such as the hardening and softening of the same material. The size and composition of these crystallites play a pivotal role in determining the overall behaviour of the related metals. The process of heat treatment is designed to manipulate these governing properties of the metal through controlling the rate of diffusion or cooling. Heat treatment is basically used for improving or restoring the manufacturability of a product. Some of the most common forms of heat treatment methods include annealing, hardening, precipitation, case hardening, selective hardening, ageing and stress relieving.

High Speed Tool Steel has very high carbon and vanadium contents for for exceptional abrasion resistance. It is well suited for premium cutting tools of all types, particularly those used for machining abrasive alloys, castings, and heat-treated materials. The high carbon content of this grade allows it to be hardened in excess of 65HRC. However, the high hardness and high vanadium carbide content make it more difficult to grind after heat treatment Tungsten high-speed tool steels are primarily used for cutting tools such as broaches, chasers, cutters, drills, hobs, reamers, and taps.
All high-speed tool steels depend on the solution of various complex alloy carbides during austenitizing to develop both their heat-resisting qualities and cutting ability. These carbides do not dissolve to any appreciable extent unless the steel is heated to temperatures approaching the melting point of the steel.

Tool steels are important materials and cover a wide range of compositions from simple plastic molding die steels or water-hardening carbon steels to very highly alloyed high-speed steels. Even more exotic compositions can be achieved by the powder metallurgy route, Tool steels usually contain significantly more alloying elements than alloy steels. Approximately 70 types of tool steels are available in India. The reason for so many types of tool steels is evolutionary development over a period of many years and the wide range of needs that they serve. Tool steels have properties that permit their use as tools for cutting and shaping metals and other materials both hot and cold. The tool steels are grouped into seven major groups, and subdivided into subgroups.
They are Water - Hardening, Shock-resisting, Cold-work, Hot-work, High-speed, Mold, Special-purpose If we are to see the true microstructure of steels, such as tool steels, we must properly prepare them.
