THE EFFECTS OF THREE AQUEOUS ENVIRONMENTS ON HIGH-STRESS LOW-CYCLE FATIGUE OF AN 18% NICKEL MARAGING STEEL

Abstract

The effects of aqueous environments upon high stress intensity crack propagation in the 200 KSI and 250 KSI grades of 18% Ni maraging steel are being investigated in an effort to provide data useful in the prediction of the reaction of pressure vessels of these materials to a limited number of pressurization cycles. This is a report on the results of tests on base plate and weld metal specimens of the 200 KSI yield strength maraging steel. Work on the 250 KSI yield strength steel is continuing.
