4 Reasons Duplex Stainless is replacing Conventional

Duplex stainless steels are less prone to Stress Corrosion Cracking (SCC) than austenitic steels like 304 and 316. Although there is no single measure of corrosion resistance, to rank the different grades, the Pitting Resistance Equivalent Number (PREN) method is often used. The formula for this is PREN = %Cr + 3.3 x %Mo + 16 x %N. Pitting Corrosion - Rolled Alloys, Inc.Pitting corrosion is in itself a corrosion mechanism, but is also a form of corrosion often associated with other types of corrosion mechanisms. It is characterized by a highly localized loss of metal. In the extreme case, it can appear as a deep, tiny hole in an otherwise unaffected surface.
