E N G I N E E R I N G - Chemical Data TM CHEMICAL RESISTANCE CHART Notice: The Chemical Resistance Chart given on the following pages is intended as a general guide for rating the resistance of typical engineering materials to common industrial chemicals. It is not intended as a guarantee of material performance. The ratings in the chart are based on data obtained from technical publications, material manufacturers and laboratory tests. The information given in the chart should be used as a first approximation for material selection, rather than the final answer. This is because chemical effects are dependent on many factors, which can cause chemical ratings to change within a given application. Such factors include variations in temperature, pressure and concentration, chemical combinations, impurities or filler materials, aeration, agitation and exposure time. It is recommended that pumps and materials first be tested under simulated field service conditions. Never test or operate a pump before acceptable chemical ratings have been obtained and the proper safety precautions have been taken. Interpretation of Chemical Resistance Ratings Rating Meaning CR < 0.002 Excellent – Virtually no effect; very low corrosion rate. A B Good – Minor effect; low corrosion rate or slight discoloration observed. C Fair – Moderate effect; moderate to high corrosion rate. Softening, weakening or swelling may occur. Not recommended for continuous use. D N Notes: 1 2 3 4 5 CR < 0.05 0.002 < CR < 0.02 0.05 < CR < 0.5 0.02 < CR < 0.05 Units in/yr mm/yr in/yr mm/yr in/yr 0.5 < CR < 1.3 mm/yr Severe Effect – Immediate attack, explosive or very high corrosion rate. Not recommended for any use. CR > 0.05 CR > 1.3 in/yr mm/yr No Data Available —- —- Ratings for all chemicals apply at room temperature unless chemical is molten (e.g., paraffin wax, sulfur, etc.). Ratings for Carbon apply to Graphite-grade Carbon (i.e., Graphite or Carbon-60). Ratings for SiC apply to Self-Sintered Silicon Carbide. Ratings for Ceramic apply to Ceramic Aluminum Oxide (Al2O3). Ratings apply to chemicals at 100% concentration (except for salts which are based on aqueous solutions) unless stated otherwise.
