Material Notes:
CPM 154 is CPM-manufactured version of Crucible’s standard 154 CM. The CPM manufacturing process produces a uniform distribution of the carbides in this grade, giving this CPM 154 easier grinding and polishing, plus better toughness, than conventional 154 CM, while retaining similar heat treat response and wear properties. CPM 154 offers better corrosion resistance, better wear resistance and better hot-hardness than 440C, plus higher toughness. For knifemakers, it offers better edge retention and chipping resistance than 440C.Information provided by Crucible Industries
