        K Cast Iron
      • K68

        Composition: A hard, low binder content, alloyed grade WC/Co fine-grain grade.
        Application: The K68 grade has excellent abrasion resistance for machining cast irons, austenitic stainless steels, non-ferrous metals, non-metals, and as an alternative to the K313 grade on most high-temperature alloys. Use as a general-purpose grade for non-ferrous materials.

        steels, sintered powdered metals, and heavy cuts in hardened steels
        (>45 HRC). Also use for finished chilled cast iron and fully pearlitic cast
        iron. Do not apply on finishing hardened steels. The solid KB9640 also
        can be effectively applied when roughing hardened steels.
