    HAP40 High Speed Powder Semi-stainless Steel

    Looking for ultra high performance knife steel? Look no further! Hitachi's HAP40 strikes a balance between hardness, toughness, and wear resistance to provide some of the best edge retention in the game.

    It can rust and will definitely stain, but it is more forgiving than white or blue carbon steels. Make sure to wash and dry your knife directly after use. However, after a nice strong patina has formed on the blade they are less likely to rust. Patina is your friend!

    Steel Composition -  Carbon (C) 1.27–1.33%, Chromium (Cr) 3.7–4.7%, Molybdenum (Mo) 4.6–5.4%, Tungsten (W) 5.6–6.4%, Vanadium (V) 2.8–3.3%, Cobalt (Co) 7.5–8.5%
