LONG TERM CORROSION TESTS OF MATERIALS FOR THERMAL DECOMPOSITION OF SULPHURIC ACID
The corrosion resistance of tubes of Incoloy 800 and AISI 310 SS has been studied in a mixture of air and H-2SO-4 vapours at 1 bar pressure. The duration of the test was one year (8500 h). The temperatures of the tubes ranged from 400 to 700 degrees C for SS AISI 310 and from 400 to 900 degrees C for Incoloy 800. The extent of the attack was determined by demeasuring the scale thickness and the penetration depth on cross sections of samples taken from several zones of the tubes. X-ray diffraction and SEM X-ray microanalysis techniques were used.
