Materials Appreciation and Optimization

To indicate, approximately, the general trend of parallel appreciation of materials, selective checkoffs are discussed in this section. These can, of course, vary for different materials or designs and a selective adjustment will be required. 

It is obvious from the contents of these selection lists that a thorough expert knowledge is required, both in engineering and in corrosion control, to complete and evaluate the required data. Only very 

Mild steel (cold rolled strip coil) 593.25 

Austenitic stainless steel (cold rolled sheet) 3500 

The data obtained from such a selection list, after appropriate evaluation and comparative appreciation, should serve as a base for a decision as to whether the appreciated conglomerate of material and its fabrication methods are suitable for the considered purpose. Although in some cases a clear-cut confirmation of suitabihty may be secured, in many more cases several materials and methods may be evaluated before the optimal one is found. Even then, such materials will not always satisfy all required properties and under such circumstances the most satisfactory compromise should be accepted.
