An American steel from Crucible, CPM-S110V is one of the top super steels of today and is cousin to CPM-S90V. It features incredible edge retention and wear resistance, and very high corrosion resistance. It is a very expensive steel, and only comes in top of the line knives. CPM-S110V's extreme wear resistance is due the incredible amount of Vanadium in the alloy, and as a result it can be very difficult to grind or sharpen.
CPM-S110V is a high-alloy martensitic stainless tool steel manufactured by the Crucible® Particle Metallurgy (CPM) process. This process begins with a homogenous molten bath of high-alloy steel that is forced through a nozzle under high-pressure nitrogen gas to create a spray of small spherical droplets that quickly solidify into powder particles. The small size of the particles forms micro-ingots, drastically reducing the alloy segregation in the steel and ensuring an extremely fine carbide microstructure when the powder is processed into finished steel.
Carbon 2.8%, Chromium 15.25%, Vanadium 9%, Molybdenum 1%, Niobium (Columbium) 3.0%, and Cobalt 2.50%. Typically Rockwells at 58-61 Rc.
