Process Equipment Corrosion / Materials Compatibility Guide

Make sure your equipment
is compatible with your process!

Here is a handy quick reference guide for corrosion and material compatibility that can be applied for process control equipment (thanks to QCI Valves).

This chart is a guide to the engineer in the selection of materials for corrosive services. No one material can be expected to handle the wide variety of corrosive media found in industry today.  Therefore, the user must decide,  based on experience, which properties are  of prime importance in their application.

The process equipment in contact with the media should carry an A Rating. This chart is intended to be a guide, and if any questions exist on the application of a material, actual tests should be performed to determine the suitability of the material.  When in doubt, ALWAYS consult an application expert.
