Knowledge Hub

Heat treating is a group of industrial and metalworking processes used to alter the physical and sometimes chemical properties of a material.

Below are few basic terms.

All types of heat treatment process


The primary purpose of an annealing treatment is to reduce the hardness of a material and facilitate the progress of subsequent manufacturing operations. Annealing is commonly used after casting, forging or rolling to soften materials and minimise residual stresses, improve machinability, and increase ductility by carefully controlling the microstructure. Many steels in strip form are annealed, as are most tool steels and stainless steels. Non-ferrous alloys are also annealed.


It is used to harden, soften, or modify other properties of materials that have different structures at low and high temperatures. The type of transformation depends on the heating rate, soak temperature, soak duration and cooling rate.


It is a process of cooling a metal at a rapid rate. This is most often done to produce a martensite transformation. In ferrous alloys, this will often produce a harder metal, while non-ferrous alloys will usually become softer than normal.


Hardened steel is generally followed by tempering process where steel is heated to relatively much lower temperature and time. Hardening followed by tempering process improves hardness and elasticity of steel.


It can soften, harden or stress relieve a material, depending on its initial state. The objective of the treatment is to counter the effects of prior processes, such as casting, forging or rolling, by refining the existing non-uniform structure into one which enhances machinability & formability.

Stress Relieving

It is applied to both ferrous and non-ferrous alloys and is intended to remove internal residual stresses generated by prior manufacturing processes such as machining, cold rolling and welding.
