Effects Of Proper Annealing






Category: HEAT TREATMENT OF STEEL

Proper annealing of low-carbon steels
causes a complete solution or combination to take place between
the ferrite and pearlite, producing a homogeneous mass of small
grains of each, the grains of the pearlite being surrounded by
grains of ferrite. A steel of this refinement will machine to good
advantage, due to the fact that the cutting tool will at all times
be in contact with metal of uniform composition.

While the alternate bands of ferrite and pearlite are microscopically
sized, it has been found that with a Gleason or Fellows gear-cutting
machine that rough cutting can be traced to poorly annealed steels,
having either a pronounced banded structure or a coarse granular
structure.
