The Advantages of Metal Heat Treatment
There are some of the materials that may need to be altered in their structure during the processes of manufacturing. 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 essentially achieved by employing some kinds of controlled heating and cooling procedures.
To put it precisely, it is good to note the fact that the heat treatments do actually vary and they are basically influenced by the type of metal and the particular mechanical properties required for the parts’ use. 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.
Like has been mentioned above, apart from aiding in altering a metal’s physical properties, heat treatments as well help a great deal in some other manufacturing processes. Some of the advantages of metal heat treatments are such as the fact that it relieves stresses and as such making the parts easier to work on and as well makes the material stronger. Alongside this is the fact that this as well makes the material a lot more resistant to wear and tear as a result of the fact that the wear and tear resistance characteristics will be added to them, and as well the material will have been made a lot more ductile or flexible. One of the metals that tends to benefit greatly from heat treatment technologies is steel especially in the manufacturing processes like hot forming or welding as these tend to lead to high build up of stresses. Heat treatments are of varied kinds and some are as we have mentioned below.
The first kind is annealing and solution annealing. The process basically makes the material more uniform and easy to machine all thanks to the fact that it so refines the grain structure of the material. Solution annealing particularly helps achieve corrosion resistance and better ductility.
Talking of the other methods of metal heat treatments, hardening and tempering is the other. 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. The metal may then be taken through another cycle of heating for tempering purposes which essentially gets to achieve it better ductility.
