Aogami literally translates as: "blue steel" and therefore "Blue Super Steel" for Aogami Super. Manufactured by Hitachi Metals Ltd, this carbon steel grade has one of the highest hardness levels and is one of the most renowned in Japan. In addition to containing more carbon, chromium and tungsten than Aogami #1, it also contains molybdenum. The high carbon content results in higher hardness, but in return, it reduces the corrosion resistance and makes the steel more brittle. Chromium and molybdenum counterbalance the effect of the high carbon content by improving corrosion resistance. While tungsten greatly increases the wear resistance of the steel to make it less brittle. This makes it, objectively, a superior carbon steel on a practical level than other steels in this category.
