Abstract:
This invention pertains to plastic injection mold tooling, and also large forgings, formed from a low carbon mold steel having markedly increased hardening and hardenability properties in large sections as contrasted to currently available commercial products. The above attributes are obtained together with equal or better machinability and improved mold parting line wear. When manufactured in conjunction with a double melt process, this invention can improve significantly polishing characteristics and other attributes of molded parts in tooling sets.

Claim (Index 15):
A method of manufacturing plastic injection molding tooling having excellent hardenability in sections of 20 inches and larger, said method comprising the steps of:\n (1) forming a steel melt having less than all of the alloy ingredients in a heating unit; (2) transferring said melt to a receptacle to thereby form a heat; (3) heating, further alloying of the alloy composition into specification and refining said heat by stirring using argon purging, magnetic stirring or some other mixing method; (4) vacuum degassing, teeming and casting said heat to form ingots by bottom pouring; (5) remelting said ingots; (6) hot working said ingots to form mold and die blocks having cross sections of 20 inches and larger, said mold and die blocks comprising 0.05 to 0.20 percent by weight vanadium; (7) heat treating said mold and die blocks by quenching and tempering; and (8) forming plastic injection molding tooling from said quenched and tempered blocks.
