  • Publication number: 20160339540
    Abstract: The methods including applying a corrosion resistant alloy to a metal substrate to create a bimetal blank. The bimetal blank can undergo a variety of shaping and machining operations to form the net shape and internal structures of the part. Further, the part can undergo a finishing operation (e.g. polishing) to create the desired cosmetic appearance on the exterior surfaces and remove any surface imperfections resulting from the shaping and machining operations.

  • 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.
