Higher demands on outlet steam conditions has led to increased use of modified low alloy materials (9-12% Cr), such as Grade 91. The superior high temperature material properties of these types of steels (strength, fatigue resistance, creep resistance, improved steam oxidation resistance) gives the designer advantages with respect to boiler reliability and thermal performance. The advantages of using this type of materials are many; however, the long-term integrity has been a concern to the industry ever since the first installations.
