With the advancement of science and technology, there has been an improvement in each and every sector like health, entertainment, finance etc. A number of useful and improved devices and systems have been introduced. The lives of people have changed for something better. The process of annealing is also a great contribution to science. It is in fact the most useful and effective heating treatment. It is a method, which mainly includes heating the steel by adjusting its temperature and then cooling it down at a proper rate, keeping in mind the object of machinability, obtaining the greatly desired structure, removing the stresses etc. In full annealing, the steel is generally heated to a definite temperature where the carbide is taken into consideration either partly or wholly. The steel then cools down gradually in the furnace. Sub-critical annealing is basically performed at a temperature just below where carbide starts to be taken into consideration. There are many other kinds of heating treatment like Ageing, Carbonitriding, Carburising, Induction Hardening, Homogenising, Normalising, Stress Relieving, Shot Blasting, Tempering, Case Hardening etc. These processes are basically performed on materials like alloy steels, carbon steels, stainless steels, tool steels, die steels and cast irons. Every heat treatment process has its own advantages. Annealing is thus no exception. It offers a number of benefits too. Read some of its advantages as given below: • It makes steel softer • The ductility of the steel increases • The improves steel’s machinability • The ductileness of steel increases • This heat treatment process increases the toughness of the steel • It enhances the homogeneity in the steel • This popular heat treatment method refines the grain size of steel • It makes the steel prepared for further heating treatment There are basically 3 stages in annealing. * Recovery phase—It causes the metal to soften by removing the crystal defects and the inner stresses. This phase includes all the aspects of heating treatment of metal that occurs prior to the formation of strain-free grains. * Recrystallization—The strain free grains form into a nucleus and grow in order to replace the ones that are deformed by the inner stresses. * Grain Growth—If this heating treatment process is continued after completion of recrystallization process, there will be a sure occurrence of grain growth. In this stage, the microstructure starts coarsening and this might cause the metallic element to have very less mechanical properties. There are a number of organizations that offer heat treatment processes. But it is always better to opt for a reputed center. It is wise to do some research on this issue. Internet is the best place to do this research. It can help you in taking the right decision. You can read the reviews and comments of the people before using the services of a company. Always hire the services of an authorized and licensed heat treatment service provider. Make sure the company you have chosen uses the right equipments while promising to offer quality services at reasonable price. Are you looking for a reputed heat treatment organization?
