High Temperature Oxidation of a Commercial Cr-Mn Austenitic Steel in Air
THE OXIDATION OF AN AUSTENITIC STEEL CONTAINING 18 PERCENT CHROMIUM AND 12.3 PERCENT MANGANESE AT 800-1000 DEGREES C IN AIR OCCURS AT A SLOWER RATE THAN THAT OF A STEEL CONTAINING 9.5 PERCENT CHROMIUM AND 17.5 PERCENT MANGANESE. HOWEVER, THE RATE OF CORROSION OF THIS 18 PERCENT CHROMIUM ALLOYS IS STILL LARGE IN COMPARISON WITH THE CASE OF FORMATION OF A CONTINUOUS CHROMIA SCALE AT THE BASE OF SCALE LAYER. THIS RESULT IS ATTRIBUTED TO THE NEGATIVE EFFECT OF THE MANGANESE OF THE THERMODYNAMIC STABILITY OF CR2O3.
