Corrosion Data — Material Selection Guide

The ratings furnished in this listing have been developed from information furnished by manufacturers of the raw materials, technical publications and industry applications. This information may be considered as a basis for evaluation, but not as a guarantee.

Consideration must also be given to fluid velocity, abrasion, and the effects of combining fluids. Materials should be tested under actual service to determine suitability for a particular application. Data supplied is for fluids at ambient temperatures except as noted.

A = Excellent
B = Good
C = Fair
D = Unsatisfactory
- = Not tested
