Abstract

PURPOSE:To provide a 18% Ni-system maraging steel having a high strength and a toughness, by forming the crystalline particles to an extremely minute size while preventing the particles from thermal degradation and being mixed with one another, when producing the 18% Ni-system maraging steel.
