Mechanical designation

Surface treatment such as heat treatment, precise knowledge of the nature of a
material is required to establish an appropriate range of treatment.
The lesser of a steel variation property may result in the use of a range of preparation or
excessively different treatment of type range.
In heat treatment of a composition variation has a significant influence on the position of the points
transformation, and the possibility of treatment that follows (time temperature modalities
cooling)
Moreover, the ease with which a metal oxide and is therefore likely to passivate must be taken into account
for the adhesion of a coating.
It is therefore necessary to know the system for encoding and decoding the nature of a material
to be coated
