There are numerous grades of austenitic stainless steel and obviously selection depends on more than one criterion. However, as these alloys are primarily used for corrosion resistance, the method most commonly used for initial selection and comparison is to establish PREn ratings (pitting resistant equivalent number). This is calculated using a simple equation to establish…

Sometimes particular alloys work in an application. Sometimes critical components and materials just don’t perform in a certain environment at all. There are factors like strength, resistance to corrosion, environmental temperature extremes, and many others, that help dictate which alloy metal to choose. Often a designer will select a familiar standard “workhorse” grade and keep…
