Normalising is a way of stabilising materials after stresses have been created during joining, forming, casting or machining operations. It is used to refine an existing
microstructure, especially relevant to steels which require further processing, e.g. carburising. It can soften, harden or stress relieve a material, depending on its initial state and chemical composition.
Normalising consists of heating a suitable material to a temperature typically in the range of 830°C to 960°C and then cooling in air.
Normalising enhances machinability; it can be applied where strict controls to mechanical strength properties are required; it helps to ensure future dimensional stability. An endothermic atmosphere to reduce scale is available for normalising cycles on steels. Normalising helps minimise distortion in the future when you come to do further heat treatment processes.
Typical Materials that can be treated:-
This treatment is mainly applied to unalloyed or alloy steels and irons.Like this page? Then Share it:
