Abstract	Six corrosion inhibitors for cooling water use were evaluated by means of a corrosometer in a laboratory bench scale test. A steel probe (Alloy 1020) was exposed and checked for the extent of corrosion in a recirculating water system, changing inhibitors and their concentrations at 40℃. A 95% inhibition was provided at the following concentrations of inhibitors. 50 ppm sodium hexametaphosphate 50 ppm commercial inhibitor A 50 ppm commercial inhibitor B 00 ppm disodium phosphate 200 ppm sodium chromate Sodium silicate was found to be use-less in this test. It was also observed that some inhibitors worked less effectively on the acid-cleaned steel probe.
