Abstract
An international initiative is underway to develop the first standardized high-temperature solid particle erosion test method for steam turbine applications, addressing limitations of the current room-temperature ASTM G76 standard. Led by EPRI, this program involves laboratories from seven countries in a “Round Robin” testing program, aiming to establish consistent testing procedures for evaluating erosion resistance of materials used in Ultra Supercritical (USC) and advanced USC turbines. The proposed standard will use Type 410 stainless steel tested at 30 and 90-degree impingement angles with 50-micron alumina particles at 200 m/s, both at room temperature and 600°C, providing more relevant conditions for current and next-generation steam turbine applications.
