The first and most important step toward successful use of a stainless steel is selection of the proper type for the application. Stainless steels include a large number of standard types, but these types differ greatly from one another in composition, corrosion resistance, physical properties and mechanical properties and selection of the optimum type for a specific application is the key to satisfactory performance at a minimum total cost.
