Abstract
PURPOSE: To improve the stress corrosion crack resistance of a maraging steel contg. 12W18% Ni by regulating the impurity Cu content of the steel and adding a specified amount of Ti and Ca or a rare earth element.
CONSTITUTION: 0.1W1.8% Ti and 0.001W0.1% Ca and/or Mg are added to a maraging steel contg. <0.03% C, <0.1% Si, <0.1% Mn, <0.01% P, <0.01% S, <0.01%Cu, 10.0W19.0% Ni, <9.0% Cr, 2.0W12.0% Mo, <16.0% Co and <0.5% Al. In place of the Ca or Mg a 0.003W0.1% rare earth element may be added, or 0.001W0.1% in total of Ca and/or Mg and a rare earth element may be added. The resulting steel has remarkably improved stress corrosion crack resistance as compared with a conventional maraging steel having a basic composition contg 12W18% Ni.
