Overview of The Heat Treatment
Metal treatment is done for various reasons, but the main ones are to change its physical and sometimes chemical properties. Control of the heat is an essential step in this process to ensure that the desired results are obtained. It is vital to note that there are many kinds of heat 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.
Metal hardening is the most known method of the heat treatment. Sufficient heat is applied on the metal to the point where it turns to a liquid. Impurities are added to the liquid metal to boost its hardness. It is vital to note that the quenching of the metal is done very quickly to ensure that those parties are trapped in the liquid metal.
Metals also undergoes the case hardening process. It solely concentrates on making the surface of the metal hard while the inside is still soft. 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. A metal is heated to a point where it gets physical transformation. After the heating, the metal is air-cooled. 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.
Steel can also be treated by a unique process called normalization. The temperature is higher than the one heated in annealing. Steel is held for a long time till it transforms physically. The objective of normalization is to make the steel easy to machine.
Tampering is a heat-treating process that is meant to make a metal more resilient. The process is most applicable for the iron-based alloys. Although these alloys are incredibly hard, they are brittle when used in some applications. Tampering is a necessary process that will make the alloy easy to machine. The process will change the ductility, hardness, and strength of the metal. The key to tampering is to heat the metal below the critical point.
If you are looking for metal treatment services, there are many companies today that can help you. You make the service provider is adhering to the best standards in the metal treatment services.
