Annealing is commonly used after casting, forging or other material processing routes to soften materials and minimise residual stresses, improve machineability and increase ductility by carefully controlling the microstructure.
The primary purpose of annealing is to reduce the hardness of a material for subsequent machining. This process can be carried out at a variety of temperatures typically in the range 830°C to 960°C .A controlled temperature and cooling is also often necessary to ensure the correct material structure.
Annealing can be applied to iron castings which exhibit chill.
Materials that can be annealed:-
All metallic materials can be successfully annealed, including ferrous and non-ferrous materials.Like this page? Then Share it:
