PREN value lookup for stainless steel materials

Thread Content

Where can I find the PREN values, which are the corrosion resistance parameters for various stainless steels?
Reply #22019-06-25
Calculated based on standard elemental contents

For example, regarding the PERN value specified in ASTM A890, the standard requires it to be greater than 40; the calculation formula is %Cr + 3.3%Mo + 16%N must be equal to or greater than 40.

Okay, thank you! Such a formula was also seen elsewhere: PREN=%Cr+3.3×(%Mo+0.5×%W)+16×%N
