Can Sodium Cause Metal Corrosion or Other Side Effects ?

2001

When a rubber compound contains high Sodium (app. 50,000 ppm) and Chloride (app. 1000 ppm) is cured at 175 ° on a Stainless Steel or Chromium or Titanium surface mold, will corrosion or any side effect happens ?

I need the answer urgently ! Your immediate reply will be very much appreciated.

Thanks & Regards,

The problem is the chlorides not the sodium. They will trap the humidity and form hydrochloric acid (HCl). At the temperature mentioned this can corrode most any metal. Yet, stainless steel of high nickel content (austenitic) might last enough. I think titanium might also last, but definitely not chromium plating.

Good luck.
