Knife Steel

We offer several grades of steel for the knife industry in sheet, plate or cut to size pieces.

Our conventionally melted steels include 440-C, D-2 and 154-CM. We also carry the full line of CPM® steels. The CPM® process offers distinct advantages over conventionally melted material. Alloy segregation is minimized and the process produces a very fine microstructure. Cutting applications where edge toughness is required is improved greatly by the CPM process because of the elimination of large carbides. You can also use a much higher alloy content in the CPM® steels which improves the toughness and or wear resistance of the knife. CPM® steels make blade fabrication easier for the knife maker because of consistent heat treat response, predictable size change after heat treating and excellent grindability.

We stock several sizes and grades for quick deliveries.
