Pitting Index for Alloy 825?
Pitting Index for Alloy 825?
(OP)
I know that Pitting ndex or PREN are applied to Duplex and Super Duplex Grades. Is this formaula also applicable to Alloy 825 material?
Is it necessary to modify the PREN formula(As defined in NACE) to suit 825 material since "N" is not part of 825 material.

“High-Performance Age-Hardenable Nickel Alloys Solve Problems in Sour Oil and Gas Service” rates the corrosion resistance using CPT and PREN

Look up CPT (CCCT) values. It is best if your source has copared a few different alloys, that way you can see if the data line up with other sources.

Corrosion, every where, all the time.
Manage it or it will manage you.
