ABSTRACT:
A powder-metallurgy-produced, essentially titanium-free, nickel-containing maraging steel article such as for use in the manufacture of die casting die components and other hot work tooling components. The article preferably contains an intentional addition of niobium. The article may be produced as a hot-isostatically-compacted, solution annealed, fully dense mass of prealloyed particles, or alternately, as a hot-isostatically-compacted, plastically deformed and solution annealed, fully dense mass of prealloyed particles.
