| Abstract: | A corrosion test is made by hanging sliced samples of ferritic stain- less steel 000Cr30Mo2 and 000Cr26Mo,austenitic stainless steel 1Cr18Ni- 9Ti and industrial-purity nickel in the caustic workshop of the Inner Mongolia Chagannuor Soda Mine.Corrosion rates are measured,corrosion- resistance degrees are determined,and,by means of the electronic micro- scope,corrosive morphologies and characteristics of passive films are observed.All the results show that both the high-purity high-chromium ferritic stainless steel 000Cr30Mo2 and 000Cr26Mo and the industrial- purity nickel possess fine corrosion resistance in the aqueous caustic of the Inner-Mongolian natural soda.Therefore,it is suggested that the high-purity ferritic stainless steel 000Cr30Mo2 and 000Cr26Mo be used to make parts of the evaporator which are subject to corrosion in preparing caustic soda. |
