The discovery of stainless steels, about 100 years ago, made possible large scale building of equipments and devices that are corrosion and oxidation resistant. Knowledge acquired in the development and improvements made in these steels has later been used in the development of nickel or cobalt-base superalloys. Despite these developments, austenitic stainless steels are still nowadays widely used, mainly due to their simple processing and their lower price if compared to the nickel or cobalt-base superalloys. For instance, the ASSs are used at high temperatures in the following industries: aerospace, heat treating equipment, mineral and metallurgical processing, chemical processing, petroleum refining and petrochemical processing, ceramic, electronic, and glass manufacturing, automotive, pulp and paper, waste incineration, fossil fuel power generation, coal gasification and nuclear.
