- Normalising – the goal is to soften the rough and uneven primary structure to achieve optimal mechanical properties for the particular material, at the least possible tension inside the casting.
- Homogenisation annealing – reduces the differences in chemical composition, and induced dendritic and band dissolving through mixing and improvement of the homogeneity of the casting.
- Quenching and tempering – achievement of a controlled amount of hardening structures, particularly martensite, respectively bainite.
- Stress relieving – removing a large part of the internal stresses in castings which are the result of both contraction and uneven cooling of strong and weak parts of the casting in the mould.
- Soft annealing – facilitating finishing of castings, including prevention of cracking when firing risers and improvement of machining capability.
- Stress relieving after welding – removing tension after production welding.
- Homogenisation of welded sections and achievement of minor differences in hardness of the base metal, transition layer and weld metal.
- Ferritisation annealing – possibility to change the structure of the base in nodular cast iron, remove the vitreous after burning, welding, etc.
