Abstract

PURPOSE: To improve the delayed rupture characteristics of a Co-free maraging steel in the environment of an aqueous soln., by increasing the Mo, Ti and Si contents of a dead soft maraging steel so as to provide a specified composition.
CONSTITUTION: This Co-free maraging steel with superior delayed rupture characteristics has a composition consisting of, by weight, ≤0.03% C, ≤0.1% Mn, ≤0.01% P, ≤0.01% S, 18W20% Ni, 1W6% Mo, 0.4W3% Ti, ≤0.5% Al, ≤0.1% Cu, 0.01W7% Cr, 0.1W2% Si and the balance essentially Fe. To the composition may be added 0.001W0.05% in total of one or more among Ca, Mg and a rare earth element.
