... is higher than in subcritical units. Because of this, the furnace tubes act more as superheaters than as water-walls. This necessitates the use of a higher grade of materials, such as the high-alloy steels, in the furnace. In turn, materials having higher creep strength and greater oxidation and corrosion...
