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.
