Some Helpful Information on Heat Treatment Solutions

The process of heat treatment includes things such as controlled heating and cooling metals with the aim of altering their mechanical and physical qualities without changing their shapes. In a few cases, this process is done inadvertently as a result of the manufacturing approach which could either heat up or cool the metal like welding or forming. Below are some heat treatment solutions so as to grow your knowledge.

Annealing is a method of steel heating and maintaining the temperature of the material at a specific temperature by cooling it down to a suitable rate. This enhances the softness, machinability and cold working features of the steel and even aids in eliminating the stresses of the material thus it gets the desired structure. In full annealing, the material is heating to a temp where the carbide turns into a solution completely or in part and then is cooled down. Sub critical annealing occurs at a temperature below the temperature where the carbide begins to become a solution.

The process of ageing is one that leads to structural changes. This normally occurs in definite alloys and metals at temperatures which are high or atmospheric temperature. Ageing has different effects; proof stress, hardness values and maximum stress increase while the ductility goes down. There are particular conditions in which ageing is achieved through heating at an elevated temperature. This is typically known as artificial ageing and it results in precipitation hardening.

Carburizing is a procedure which includes introducing carbon to the steel’s surface area which has a low carbon content. It could be effected by heating it inside a liquid, gaseous or solid medium that has carbon. When done at elevated temperatures, it provides a supply of the carbon which will be absorbed by the carburized substance. The carbon concentration and its depth in the steel surfaces are changed by controlling the time and temperature which are needed by the heat treatment.

Hardening is a process which uses heat treatment to harden the material. Usually, this entails heating to a higher temperature than the critical range and controlling the temperature to a rate where diffusion is carried out by quenching in water, air or oil.

In the induction hardening procedure, the steel is hardened through heat treat. It is done by alternating a magnetic field to that of the temperature which is above or close to the transformation range then quenching follows it.

Normalizing is a heat treatment method in which heating to is done and when required, even maintaining the temperature at a certain level and then cooling down the cool air follows. This provides for quicker cooling at a medium level.
