Some Helpful Information on Heat Treatment Solutions

The procedure of heat treatment involves controlled heating and then cooling the metals so as to change their physical and mechanical properties without altering their shapes. In some cases, this process is undertaken inadvertently due to the manufacturing method which either heat up or cool the metal such as welding or forming. Below are some heat treatment solutions so as to grow your knowledge.

Another method of heating steel is annealing and it keeps it to a particular temperature by cooling down at a suitable rate. This improves the qualities of the metal like the softness, machinability, cold working characteristics and is quite helpful in doing away with its stresses and therefore, it gets the structure which one desires. The material is heating up to a specific temperature in full annealing and thus the carbide turns into solution either fully or partially and then it is cooled down. Sub critical annealing occurs at a temperature below the temperature where the carbide begins to become a solution.

The procedure of ageing results in structural changes. Typically, this happens in specific metals and alloys at atmospheric temperature or temperatures which are high. Ageing has different effects; proof stress, hardness values and maximum stress increase while the ductility goes down. There are specific conditions where ageing is achieved through heating at a high 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 might be done by heating it in a solid, liquid or gaseous medium that has carbon. When conducted in high temperatures, it offers a supply of carbon which the carburized substance supplies. The concentration of the carbon and the depth which is in the surfaces of the steel is altered by managing the time and temperature required by the heat treatment.

Hardening is a procedure which improves the hardness of the steel though the use of heat. Normally, this implies heating to a temperature which is more than the critical range by maintaining the temperature at a range where diffusion will be achieved by quenching in air, oil or water.

In the induction hardening procedure, the steel is hardened through heat treat. It is carried out by alternating the magnetic field to the temperature which is higher or near to the transformation range and then it is followed by quenching.

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. The purpose of this is to facilitate faster cooling at a medium level.
