THE INVESTIGATION OF STRESS CORROSION CRACKING OF HIGH STRENGTH STEELS

Abstract

Stress corrosion susceptibility of maraging steel increases with strength level. Complete immunity to failure can be obtained with the conventional martensitic steels by employing a sufficiently high tempering temperature. The addition of 3% NaCl to distilled water lessens the susceptibility of the test alloys to stress corrosion failure. In distilled water environments controlled to 120 and 160 F, all specimens failed except for a low alloy steel tempered at 1100 F. Environmental temperature was found to have a great effect on the failure time of maraging steel with the susceptibility doubling for every 18 F increase in temperature. By application of the proper amount of cathodic current, stress corrosion cracking of maraging steel may be stopped. However, if the current is increased over this critical amount, no protection is furnished.
