2. Final choice
To refine the choice of the optimum grade when the alloy type is selected, simulation tests should be carried out in the laboratory or, preferably, on prototypes under industrial conditions. These will enable us to observe the influence of the nature and quantity of minor elements, as well as that of the microstructure, in particular grain size and the quantity and distribution of any precipitates. A grade is then selected with the highest resistance to dry corrosion, i.e. the best compromise between chemical resistance and mechanical resistance, depending on the application envisaged.
Validation of the final choice does not stop at this stage, however, as the recommender must take into account the three non-scientific criteria of desired shape, cost and availability (figure
