Process Chemicals Corrosion. Chlorine. The flow rate of liquid chlorine through carbon steel pipework is restricted to 2 m/s to avoid removing the ferric chloride coating on the pipe surface which protects against erosion / corrosion of the carbon steel. Wet chlorine gas corrodes mild steel.
Does hydrogen peroxide corrode metal? My sink has some mold deposits in the bottom of it and they have been there for many years; although they seem to be getting worse with time.
