The effect of simulated aerodynamic heating on the strength of three high strength steels used in rocket motor cases was investigated. Low alloy steel RS 131 (1% Cr-Mo) and 18% Ni maraging steels DTD 5212 and RPE 1090 (G 125) were tested at temperatures up to 700 deg C attained in 5 seconds. The results show that the reduction in short term strength of these metals at elevated temperatures is not so great as to preclude their use in Mach 3 missiles and in some types of Mach 4 missiles.
