WebPitting resistance equivalent number ( PREN) is a predictive measurement of a stainless steel's resistance to localized pitting corrosion based on its chemical composition. In general: the higher PREN-value, the more resistant is the stainless steel to localized pitting corrosion by chloride. PREN is frequently specified when stainless steels ...
