How to Choose Stainless Steel Using the PREN Index?
Pitting resistance equivalent number (PREN) is a predictive measurement of the pitting corrosion resistance of various types of stainless steel. How to choose the most suitable steel? For help in choosing the most suitable steel you can rely on numerical index PREN (Pitting Resistance Equivalent Number). The higher PREN-value, the more pitting corrosion resistant the […]
