ABSTRACT:
A martensitic hot work tool steel mold and die block article for use in the manufacture for molds for plastic injection molding, die casting die components, and other hot work tooling components. The article has a hardness within the range of 35 to 50 HRC, a minimum Charpy V-notch impact toughness of 3 foot pounds when heat treated to a hardness of 44 to 46 HRC and when tested both at 72.degree. F. and 600.degree. F. The article is an as hot-isostatically-compacted, fully dense, heat-treated mass of prealloyed particles which contain sulfur within the range of 0.05 to 0.30 weight percent. The hot work tool steel includes maraging and precipitation-hardening steels of this type.
