C: Review requiredDo not select from the table alone

D: Not recommendedUse a different candidate material

Reference scope: Ratings are preliminary screening information, not a corrosion-rate model. The table does not interpolate unlisted concentration or temperature values. Material family labels do not certify every cast or wrought grade as identical.

Confirm the material before you buy

Final suitability depends on concentration, temperature, impurities, solids, aeration, velocity, sealing materials and the complete wetted system.

Chemical compatibility FAQ

Does an A rating approve a material for purchase?

No. It means the material family is generally resistant under the listed reference condition. Confirm actual concentration, normal and maximum temperature, contaminants, aeration, velocity, solids, sealing materials and the full wetted system.

Why are CF8M and CN7M not separate rating columns?

The current table is organized by broader material families. A cast grade may be commercially related to a wrought family, but this page does not claim that every grade has identical performance in every listed condition.

Can the table estimate an unlisted temperature or concentration?

No. Filters only return exact conditions already present in the dataset. Unlisted conditions require a separate engineering and source-data review.

Does the table include seals and other non-metallic wetted parts?

No. The ratings compare metallic material families. Elastomers, mechanical seal faces, gaskets, sleeves and other wetted components must be checked separately.

What should I send for a material review?

Send the chemical or mixture, concentration, normal and maximum temperature, solids, impurities, current pump model and material, required component, and any available nameplate photo, BOM or drawing.

Need engineering confirmation before quotation?

Send the real operating conditions and the pump or component information you already have. The team can then review the material family and buying route.

Use the searchable table above for listed service conditions. Sulfuric acid, hydrochloric acid, nitric acid and sodium hydroxide selections depend on the exact concentration, temperature and operating conditions shown in the table.

Material Selection Needs a Service Review

This chemical compatibility and resistance chart is screening guidance, not a corrosion guarantee. Consider concentration and temperature together, as well as metallic grade or cast grade, contaminants, velocity, solids, pH, chlorides and oxidizing or reducing conditions. Do not interpolate an unlisted condition automatically.
