How Beneficial Heat Treatment is to Metals
When it comes to the manufacturing processes, there are some of the materials that will at times require that they be subjected to some procedures that will change their grain structure and composition. Heat treatments are actually some of the methods that have been used for quite some time for the sake of changing metals physical properties as such improving them to be used in a wide range of industries. The change in the physical properties of the metals is achieved by use of some controlled heating and cooling procedures.
In a general sense, the heat treatments vary as per the metal type and as well are influenced by the particular physical properties so desired for the functionality of the parts. Strength often being the core need, it is as such important to ensure that the correct heat treatment procedures are followed to ensure that this is achieved.
Heat treatments, apart from helping alter a metal’s physical properties can as well be of great help in some other manufacturing processes. Following a heat treatment procedure, a material will get to attain some of the following benefits-relieving stresses and as such being so much easier to work on and above this is the fact of added strength. Besides this is the fact that this as well makes the material a lot more ductile and flexible and as well gets them to be a lot more resistant to wear and tear. Steel is actually one of the materials that tends to benefit from heat treatment processes more so in the manufacturing process such as hot forming and welding as these often see high build up of stresses. When it comes to the kinds of heat treatments, these actually happen to be of various kinds.
One is the Annealing and Solution Annealing. This process often results in a material that is more uniform and easier to work as a result of the refining it achieves in the grain structure. Solution annealing particularly helps achieve corrosion resistance and better ductility.
The other method of metal heat treatments is hardening and tempering. Hardening can be performed on certain kinds of steel metals that have a particular composition of carbon in them and it always involves the heating of the material to such high temperatures as up to 900 degrees after which they are speedily cooled as this page shows. For tempering, the material can then be subjected to another heating cycle which then introduces ductility to the part.
