Behaviour of carbon during the corrosion of stainless steel by carbon dioxide

Abstract Published information has been summarized on the behaviour of carbon during the corrosion of austenitic stainless steel in CO 2 and CO 2 -CO atmospheres within the temperature range 650–900°C. A general pattern of behaviour has emerged and has been extended by recently obtained unpublished results on a 20%Cr 25%Ni steel stabilized with niobium.
