Blossary – Heat Treatment

Home > Blossary: Heat Treatment

Heat Treatment is the controlled heating and cooling of metals to alter their physical and mechanical properties without changing the product shape. Heat treatment is sometimes done inadvertently due to manufacturing processes that either heat or cool the metal such as welding or forming. Heat Treatment is often associated with increasing the strength of material, but it can also be used to alter certain manufacturability objectives such as improve machining, improve formability, restore ductility after a cold working operation. Thus it is a very enabling manufacturing process that can not only help other manufacturing process, but can also improve product performance by increasing strength or other desirable characteristics.

Chromizing

Chromizing is also used for surface hardening of both carbon and tool steels.The components to be chromized are packed with fine chromium powder and additives.

Bronizing

Bronizing is one of the recent methods of surface hardening,which may be applied to any ferrous material but is generally adopted for carbon steel and tool steel.

Nitriding

Nitriding is most effective for those alloy steels which contain stable nitride forming elements such as aluminum,chromium,molybdenum,vanadium and tungsten.Nitriding is carried out in a ferritic ...

Carbonitriding

This process is specifically used for improving wear resistance of mild,plain carbon or very low alloy steels.Carbonitriding is carried out at low temperatures in the range 800 to 870 degree in a gas ...

Cyaniding

In this process,the parts to be heat treated are immersed in a liquid bath at 800 to 960 degree of NaCN with the concentration varying between 25 and 90 percent.

Quenchants

A medium that is used for quenching is known as quenchants.The most commonly quenchants are water,oil,salts,air,gases and aqueous solutions.

Carburizing

This is the most widely used process for surface hardening of steels.It is carried out on low carbon steel which contain from 0.01 to 0.25 percent carbon and known as carburizing steels.
