Refractory steels and alloys use in petrochemical industry

Abstract

After a brief review of some of the high temperature corrosion problems encountered in the petrochemical industry, the various factors which determine the resistance to these types of attack are considered. The importance of establishing the real service conditions is emphasised, based on the use of constitution and phase stability diagrams. These considerations are used both to interpret empirically established material selection criteria and to indicate possible paths for future alloy development.
