Chemical Resistance Data (Stainless Steel grade 304 vs 316)

These recommendations are based on available published information and should be considered as a general guide rather than an unqualified guarantee, since the resistance of metals can be affected by different factors such as concentration, temperature, presence of other chemicals.

A - Very Good
B - Good
C - Fair
D - Not recommended
