This is an industrial process which is usually performed with an aim of altering the physical or the chemical properties of metals. You may wish to have the metal in a soft or harder form and so, you will employ heating or chilling processes respectively. Advantages of carrying out metal heat treating are outlined in this article.
Where metal heat treating has been performed, you will get a metal that is more durable, tougher and whose strength has been improved. This kind of treatment causes a great improvement in terms of the mechanical properties of that given metal. Where you harden the metal by treating it using heat, you also raise its level of toughness. The alloys of that metal are normally heated to a temperature which is above the transformation temperature of the metal and thereafter it is cooled very fast to make the metal that was initially soft become harder and more tough which are much strong. After hardening your material, you can release it from stress as a form of increasing its stability.
Secondly, heat treated metals can be welded easily. Heating improves the efficiency of the metal needed in welding. The presence of the tempered microstructures present in the heat treated metals are necessary for the welding process. You will not realize immediate cooling after welding where heat treated metals have been used as they have very little residual effects. You will be okay working with these metals in your welding works as you will not have worries of cracks and distortions after the process.
Thirdly, it increases resistance to wear and tear as well as the general lifespan of the metal is lengthened. The metal gains extra strength wear it has been through heat treatment and therefore it can work efficiently without being worn out. Soft metals are prone to wear and tear and so they are termed to be less efficient and uneconomical to work with. Metals that have undergone treatment can be used widely as they withstand all the conditions without being altered unlike the soft metals. It will be economical to prevent corrosion of the metals by treating them using heat rather than incurring the expenses of buying new ones. It is unusual to realize that a metal which has been through heat treatment is being corroded for example by moisture.
You can change the magnetic and electrical properties of your metal to a form that you require using the metal heat treating method. The permeability of metals to magnetism is usually altered by heat. Heat can be used to change the magnetic and electric properties of the metal to your desired characteristic.
