Introduction to Techniques of Heat Treatment

Metal treatment is a necessary process that is meant to alter the physical and chemical properties of the metal. Control of the heat is an essential step in this process to ensure that the desired results are obtained. There are different methods of metal treatment. The metal will be less or more brittle, stronger or weaker, or softer or harder depending on the technique that is used. To get the desired results, time or application and cooling will also be varied.

The first method of heat treatment is the hardening. Heat is applied on the metal until when it liquify. To increase the hardness, impurities are added in the solution. To ensure that these particles are traps, the metal is quenched rapidly.

The other method of the metal heat treatment is the case hardening. The process only makes the surface of the metal hard. To produce the hard layer, a combination of higher temperatures and chemicals is used. Carbon is the common metal that is used in the infusion.

Annealing is one more method that you should know about heat treatment. The process involves heating the metal for a specific time for physical transformation. Air cooling is done after the heating. Annealing is done on the copper, silver, brass, and aluminum. The results of the annealing is a metal that is ductile and softer; this will make it workable. During the machining, the metal will not crack because of these properties.

Steel can also be treated by a unique process called normalization. It is heated at a temperature higher than in the annealing. It is held in the critical temperature for a long time until when it transform. The normalization seeks to make the steel machinable.

Metals are made more resilient by a heat-treating method called tampering. Tampering is mostly done on the iron-based alloys. Although the alloys are hard, their brittleness limits their applications in some areas. Tampering is a necessary process that will make the alloy easy to machine. Hardness, ductility, and strength are the physical properties that will be changed by the process. The metal will be heated below the critical point.

Many companies today offer metal treatment services. You make the service provider is adhering to the best standards in the metal treatment services. For a better understanding of the metal treatment company, you should read the online reviews; they will let you know the history and the quality of the work that is delivered by the company. It is further supposed to be timely and also efficiencies in the delivery of the work. If you are finding certified heat treating services, click on this page.
