Annealing involves heating steel to a specified temperature and then cooling at a very slow
and controlled rate. Find out more about the annealing processes.
There are several furnace types to choose from based on the size of your operation, temperature and features needed for your product.
Nutec Bickley’s precision manufacturing and decades of knowledge ensure that your annealing furnace will get the job done and stand the test of time.

Annealing is a heat treatment process in which a material is heated to an elevated temperature and held for a set amount of time and then cooled with a controlled rate.
The time at the high temperature (soaking time) is long enough to allow the desired transformation to occur. Cooling is done slowly to avoid warping/cracking due to the thermal gradients and thermo elastic stresses within the metal piece.
used to reverse the effects of workhardening (by recovery and recrystallization) and to increase ductility. Heating is usually limited to avoid excessive grain growth and oxidation.
used to eliminate/minimize stresses arising from plastic deformation during machining, non-uniform cooling and phase transformations between phases with different densities. Stress relief annealing allows these stresses to relax. Annealing temperatures are relatively low so that useful effects of cold working are not eliminated.
is an annealing heat treatment just above the upper critical temperature to reduce the average grain sizes (of pearlite and proeutectoid phase) and make more uniform size distributions. After complete transformation to austenite (austenitizing) the treatment is completed by cooling to the required microstructure.
involves austenitizing and slow cooling (several hours). Produces coarse pearlite -large grains (and possible proeutectoid phase) that is relatively soft and ductile. Full annealing is used to soften pieces which have been hardened by plastic deformation, and which need to undergo subsequent machining/forming.
involves prolonged heating just below the eutectoid temperature, which results in the soft spheroidite structure. This achieves maximum softness needed in subsequent forming operations.
