  • Process for case hardened dies in improving die life
    Patent number: 6695930
    Abstract: Steel alloys susceptible to case and core hardening comprise 0.05 to 0.24 wt % carbon; 15 to 28 wt % cobalt and 1.5 to 9.5 wt % in nickel, small percentages of one or more additives: chromium, molybdenum, and vanadium; and the balance iron. Carburized roll form and punch dies and tools made from case hardened steel alloys with a reduced hardness core provide high wear and fatigue resistance as well as improved contact and bending fatigue resistance thereby avoiding premature failure and extending the useful life of such tools.
    Type: Grant
    Filed: March 25, 2002
    Date of Patent: February 24, 2004
    Assignee: Northwestern University
    Inventors: Charles J. Kuehmann, Gregory B. Olson, John P. Wise, Carelyn E. Campbell
  • Case hardened steel blades for sports equipment and method of manufacture
    Patent number: 6458220
    Abstract: Steel alloys susceptible to case and core hardening comprise 0.05 to 0.24 weight percent carbon; 15 to 28 weight percent cobalt and 1.5 to 9.5 weight percent in nickel, small percentages of one or more additives: chromium, molybdenum, and vanadium; and the balance iron. Blades for ice skating or other sports equipment made from such alloys provide predictable and reproducible characteristics and permit fabrication with hardened edges on a ductile, strong substrate or base.
