What Does PRE Stand For?
PRE stands for Pitting Resistance Equivalent
Pitting Resistance Equivalent (PRE) is a quantitative measure used to evaluate the resistance of materials, particularly stainless steels, to localized corrosion such as pitting and crevice corrosion. The PRE is calculated based on the alloy's chemical composition, specifically the proportions of alloying elements like chromium, molybdenum, and nitrogen, which enhance corrosion resistance. A higher PRE value indicates better pitting resistance, making it a critical parameter for selecting materials for applications in aggressive environments, such as marine and chemical processing industries.
