Overview of The Heat Treatment

Metal treatment is a necessary process that is meant to alter the physical and chemical properties of the metal. To get the desired results, the heat must be monitored. It is vital to note that there are many kinds of heat treatment. The method used will determine whether the result will be softer or harder, weaker or stronger, or less or more brittle. In the process, time of cooling and heating should also be control.

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. The metal is quickly quenched to trap these particles.

Case hardening is also done on the metals. It solely concentrates on making the surface of the metal hard while the inside is still soft. Temperature and chemicals will be used to make the surface change. Carbon is the common element infused on the surface of the metal to be hardened.

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. Copper, aluminum, silver, and brass are the common metals where annealing is done. Metals that undergo annealing are workable because they become softer and ductile. In the industrial set up, annealing is done to stabilize the material during the machining; it will not crack during the process.

Normalization is a special heat treatment for the steel. Normalization temperature for steel is higher than in the annealing. Steel is held for a long time till it transforms physically. The objective of normalization is to make the steel easy to machine.

Metals are made more resilient by a heat-treating method called tampering. The process is mostly done on the iron-based alloys such as the steel. The alloys have excellent hardness, but they are very brittle for some applications. After the tampering, the metal will be easy to machine. Hardness, ductility, and strength are the physical properties that will be changed by the process. The key to tampering is to heat the metal below the critical point.

Many companies today offer metal treatment services. When you are finding a service provider, you must make sure that they have the highest standards in the metal treatment. Examine the online reviews to understand the history and the quality of work that is provided by the metal treatment company. How effective is the company in the delivery of the work? Is it time.
