4 Use of this standard
The index of material sheets contained in this standard, classified by family based on the main element used
in the chemical composition and on the alloy structure, is given in Clause 6 of this standard.
The degree of weldability or brazeability to be used is the value indicated by the material sheet considered for
the process chosen. In the operating cycle, preferably select thermal states that give the lowest degree.
If two degrees are indicated, the responsible person must select the degree that is most appropriate for the
definition of the assembly.
