CPM S110V is a high alloy martensitic stainless tool steel produced by the Crucible Particle Metallurgy (CPM) process. CPM S110V contains a high volume fraction of both vanadium-rich and niobium-rich primary alloy carbides for exceptionally good wear resistance compared to other commercially available PM tool steels. It also offers better corrosion resistance than 440C or CPM S90V.

CPM S110V is currently only available on special request in the as-HIP condition or as a clad layer on components. It is not available in forged or rolled bar lengths.

The CPM process results in a fine and uniform carbide distribution in CPM S110V compared to conventionally produced high alloy tool steels which results in relatively good machining, grinding, and toughness characteristics despite the high alloy content.
