Abstract: In current investigation, results of electrochemical as well as weight loss test conducted on steels in acidic peroxide solutions have been discussed. Electrochemical polarization test E vs. time curve, potentiodynamic as well as cyclic polarization curve were performed on stainless steels SS304L, SS316L, SS2205 and 6% Mo in peroxide solutions having H2O2 , 500 and 1000 parts per million (ppm). The pH of these solutions for electrochemical tests was kept 4 with chloride and without chloride. Chloride content varied from 0 to 1000 ppm. Weight loss test was also accomplished on above stainless steels in peroxide solutions with chloride content varied from 0 to 1000 ppm at same pH. Alongside an E-pH illustration of peroxide-water coordination were constructed. Electrochemical results of tested steels show soaring extent of localized corrosion while it is less relentless in crate of solutions exclusive of Cl- . In general, It is accomplished that acidic peroxides among/lacking Clare corrosive to steels to anecdotal amount furthermore their corrosives augments with boost in H2O2 as well as Cl-substance. The optimal material for managing these media is recommended to be SS 2205. Results of Weight loss test showed that SS 304L is found to observe high degree of uniform corrosion hence cannot be suggested for handling these media. Duplex stainless steels therefore have to be used. Both electrochemical and weight loss tests on stainless steel showed increased resistance against corrosion in order of: SS304L< SS316L < SS2205~ 6% Mo.
