AnnealingAnnealing is a heat treatment process which makes working with thick metals easy. In this procedure, metals are heated to the desired temperature and then cooled later on. This is done in order to amend different properties of a material so as to alter its different measures such as Ductility, Brittleness, and Hardness etc. NormalizationAn Annealing process mainly used to work on with ferrous alloys to provide the material with a fine-grained structure. The main purpose of this type of Annealing is to reduce brittleness. It is carried out at a temperature ranging from 20-50°C.
Normalizing improves machinability thus offering dimensional stability. Subcritical Annealing Process Annealing or Subcritical Annealing is another heat treatment procedure which ensures the extents to which a product can be subjected to cold working without breaking. The average temperature for this type of Annealing to work is 510 °C. The process is preferable to be carried out on low carbon steel.Full AnnealingThe process involves heating the material at around 50 °C above the critical temperature of steel and maintaining it for the required amount of time. The final received product is the second most ductile state a metal can be in. This process allows the metal to attain a high degree of plasticity and toughness. ApplicationOne of the most important uses of Annealing is to reverse the effects of work hardening on a product.
This process comes to use when there is no way left for a product to go further forming without resulting in cracking. Other than steel other metals such as copper and aluminum have also found to have benefited from this process. SpecificationThe compulsory specification of an Annealing furnace is the thickness of all the components of an Annealing furnace should range from 1.8mm to 30mm while the maximum operating temperature of the furnace should not be more than 800 °C. The furnace should have a capacity of taking in at least 4 ton of materials in one heating session.
