Properties of Superaustenitic Stainless Steels

Materials are characterized by various properties, including physical, mechanical, and corrosion resistance-related ones. In-depth knowledge of superaustenitic stainless steels also comes through analysis of such characteristics. Material properties represent a key information for designers because in the design process, the product features, its use, and its expected useful lifetime are affected by material attitudes. The characteristics of the material certainly influence its usability, but the reverse is also true in that constraints related to service conditions may force the choice to a specific material because others do not possess the appropriate combination of properties for effective use. Once the chemical nature of a material is clear, knowledge of its physical properties becomes important for understanding how it reacts to external stimuli such as a change in temperature or the flow of an electron current through it. The application of external stresses under various conditions helps to understand how the material reacts from a mechanical point of view. Finally, the interaction of the material with the external environment and the way the environment modifies the material provide insight into the behavior from the perspective of corrosion resistance.
