CHEMICAL RESISTANCE GUIDE FOR METALS
The following table should be used only as a guide for selecting materials for various applications. This table
does not imply a guarantee of corrosion resistance due to the fact the complicating factors, (ie; agitation,
impurities, aeration and velocity of corrosives encountered in commercial operations) cannot be realistically
duplicated in a controlled laboratory environment.
A = Excellent Resistance N = Not Recommended
B = Good Resistance Blank = Insufficient Data
C = Fair Resistance
