What is the difference between Heat Treatment and Annealing? Annealing is a method of heat treatment that includes normalizing, annealing, hardening and temper. WHAT IS DIFFERENCE BETWEEN ANNEALING. WHAT IS DIFFERENCE BETWEEN ANNEALING,TEMPERING AND NORMALIZING. And what is the capillary tube and the difference between. Sep 18, 2015 Though Annealing and normalizing are two most commonly used heat treatment methods in metallurgy which use a combination of heating and cooling operation, a distinct difference between can be noticed between the two processes, in the last cooling step. Is the heating and cooling of metals to change their physical and mechanical properties, without letting it change its shape. Could be said to be a method for strengthening materials but could also be used to alter some mechanical properties such as improving formability, machining, etc. The most common application is metallurgical but heat treatment can also be used in manufacture of glass, aluminum, steel and many more materials. The process of heat treatment involves the use of heating or cooling, usually to extreme temperatures to achieve the wanted result. It is very important manufacturing processes that can not only help manufacturing process but can also improve product, its performance, and its characteristics in many ways. Hardening Hardening involves heating of steel, keeping it at an appropriate temperature until all pearlite is transformed into austenite, and then quenching it rapidly in water or oil.

The temperature at which austentizing rapidly takes place depends upon the carbon content in the steel used. The heating time should be increased ensuring that the core will also be fully transformed into austenite. The microstructure of a hardened steel part is ferrite, martensite, or cementite. Tempering Tempering involves heating steel that has been quenched and hardened for an adequate period of time so that the metal can be equilibrated. Evermotion rapidshare. Difference Between Annealing And HardeningThe hardness and strength obtained depend upon the temperature at which tempering is carried out. Higher temperatures will result into high ductility, but low strength and hardness. Low tempering temperatures will produce low ductility, but high strength and hardness. In practice, appropriate tempering temperatures are selected that will produce the desired level of hardness and strength. This operation is performed on all carbon steels that have been hardened, in order to reduce their brittleness, so that they can be used effectively in desired applications.
