W722 VMR Steel

W722 VMR Steel

Steel name: W722 VMR
Diagram No.: 2283
Mat.No. (Wr.Nr.) designation: ~1.2709
DIN designation: X3NiCoMoTi18-9-5
Chemical composition in weight %: max. 0.005% C, 4.85% Mo, 18.00% Ni, 9.25% Co, 1.00% Ti
Steel group: Maraging high strength steels
Properties: Ultra-high-strength maraging steel. In contrast to heat treatable steels its outstanding tensile properties are not due to a hardened structure with relatively high carbon content, but to precipitation of intermetallic phases from a ductile nickel bearing matrix containing almost no carbon.
Applications: Cold heading and embossing tools, cold extrusion tools, casings, shear plates, moulds for the plastic industry, die casting tools for aluminium and zinc alloys, hot pressing tools.
Reference: Not shown in this demo version.

Heat Treatment
Solution annealing: 820ºC / Air, gas Hardness: max. 320 HB.
Ageing: 490°C / 6 hours / air Obtainable Hardness: approx. max. 55 HRC.
Diagram note: Solution annealed 820°C / 1 hour / air Age hardening: 3 h. For maximum hardness there is also the possibility to age 6 h at 490°C.
