摘要

Of all the materials used for high-temperature steam piping, X20 (12 percent chromium, 1 percent molybdenum, 1/4 percent vanadium) and P91 (9 percent chromium, 1 percent molybdenum, 1/4 percent vanadium) stand out because of their very high creep rupture properties, even at elevated temperatures. X20 was introduced in the 1950s in Germany and used in steam lines operating at temperatures of 530 degrees C and higher for fossil fuel-fired power generating sets of 150 megawatts and more. However, two factors limited its use: the extreme care needed for its fabrication and welding and its noninclusion in the American Society off Mechanical Engineers (ASME) Code B31.1
