Test on Stainless steel :

CLO2 CORROSION 304,316 SS

source: Bohner ,H.F.,Bradley ,R.L. 1991. Corrosivity of Chlorine Dioxide Used as Sanitizer in Ultrafiltration Systems.J. of Dairy Science ,74:3348-3352

Solutions Tested :

A. 500 ppm Acidified Sodium Chlorite to pH 2.7-produced 4ppm CLO2 initially,20ppm CLO2 after 12 hours 

B. 100 ppm Pure CLO2 to pH 7.2

Results after 10 day soak test at 40degreesC:

Solution A Corrosion of both 304ss and 316ss

Solution B No corrosion to either 304ss or 316 ss

The vapors of Solution A or B were noncorrosive to 304 ss and 316 ss

Conclusion : in pH 2,7 CLO2 corrosive , in pH 7.2 non corrosive even at 100ppm dosage rate

eOxide Lq chlorine dioxide has an oxidation/reduction potential of 0,95 which is lower than other commonly known decontaminating agents ,Hydrogen peroxide and bleach

This make eOxide chlorine dioxide scientifically less corrosive than other oxidative agents
