The mechanical behavior of 18Ni 300 maraging steel was determined in constant loading rate, short-time elevated temperature tensile tests at loading rates of 4000 to 400,000 psisec at temperatures from 75 to 1200F and in heating rate tests with concurrent constant loads equivalent to 25 to 85 percent of the room temperature yield strength for heating rates of 50 to 400Fsec. Results are discussed.
