TODAY, aircraft gas turbine engines are being developed to give over 28,000 lb. thrust and, while low-pressure compressor casings can be made from a magnesium-alloy casting, the operating conditions of high-pressure compressors demand high-tcnsilc stainless steel. The operating temperature of a high-pressure compressor, for example, may be about 450 deg. C, and certain specifications call for minimum ultimate tensile strengths of 135,000 lb./sq. in. with 10 percent minimum elongation at room temperature, with appropriate stress-rupture and creep properties at elevated temperatures.
