Tool steels belong to a broad group of materials that are designed to cut, punch, and otherwise shape other materials. Signicast makes tools from alloys of iron containing 0.25-2.5% carbon with substantial amounts of chromium, molybdenum, tungsten, vanadium, cobalt, and to a lesser extent nickel to achieve the desired combination of hardenability, hardness, toughness, and wear resistance. We produce castings in alloys from all the tool steel classifications.
