What is PREN (Pitting Resistance Equivalent Number)? - Instrumentation 

Pitting resistance equivalent number (PREN) is a method that is widely used as a means of comparing the relative corrosion resistance of different steels. PREN is a theoretical way of comparing the pitting corrosion resistance of stainless steels based only on their chemical compositions.
Clara Moyano, innovation engineer - Material Science at Parker Hannifin’s Instrumentation Products Division Europe, talks about PREN (Pitting Resistance Equivalent Number) and its importance when evaluating the resistance of steel to pitting corrosion.
