Annealing

Annealing is a heat treatment process used to reduce hardness, increase ductility and help eliminate internal stresses.

Recrystallisation

Recyrstallisation annealing is applied to cold-worked metal to obtain nucleation and growth of new grains without phase change.

Normalising

Through normalising the steel can obtain a more fine-grained homogeneous structure with predictable properties and machinability.

Sub-critical annealing / intercritical annealing

The soft annealing process forms an even distribution of spheroidal carbides in the steel, which will make the material softer and tougher.

Soft annealing

A high temperature heat treatment process performed around A1, the aim of which is to make a material as soft as possible.
