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 some instances, this process is carried out inadvertently because of the method used in manufacturing which could either heat up or cool the metal for example forming or welding. We share details of heat treatment solutions below so as to grow your knowledge in this field.
Annealing is a way of heating steel and keeping the material to a specific temperature by cooling down at an appropriate 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. 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 usually takes place in definite metals and alloys at high temperatures or atmospheric temperature. As a result of ageing, hardness values, ageing, and maximum increase while the ductility lowers. There are specific conditions where ageing is achieved through heating at a high temperature. This is usually referred to as artificial ageing and its result is precipitation hardening.
Carburizing is a process that involves introducing carbon into the surface layer of the steel which does not have a high carbon content. It might be done by heating it in a solid, liquid or gaseous medium that has carbon. When carried out at high temperatures, it gives a carbon supply which will be absorbed by the carburized substance. The concentration of the carbon and the depth in its steel surfaces is varied by controlling the temperature and the time which the heat treatment requires.
Hardening is a process which uses heat treatment to harden the material. 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.
Heat treat is used in steel hardening in the process of induction hardening. It is undertaken by alternating a magnetic field to that of a higher temperature or that which is close to the range of transformation and then quenching follows.
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.
