BÖHLER W722 VMR is not a classic hot work tool steel, but an ultra-high strength maraging steel. Compared to quenched and tempered steels, the material generates its high strength not through a hardened and tempered martensitic structure with a high carbon content and secondary hardening carbides, but through the precipitation of intermetallic phases from a tough nickel martensitic matrix. BÖHLER W722 VMR corresponds to material number 1.2709 (X3NiCoMoTi18-9-5) and has proven to be ideally suited for many tool steel applications in cold and hot work up to 450 °C. The Steel also is available as powder material for metal-3D-printing under the brand name BÖHLER W722 AMPO.
