Abstract (en)
[origin: WO2007058759A1] An age hardenable martensitic steel alloy is disclosed. The alloy has the following composition in weight percent. C 0.30-0.36; Mn 0.05 max.; Si 0.05 max.; P 0.01 max.; S 0.0010 max.; Cr 1.30-3.2; Ni 10.0-13.0; Mo 1.0-2.70; Co 13.8-17.4; Ti 0.02 max.; Al 0.005 max.; Ce 0.030 max.; La 0.010 max. The balance is iron and the usual impurities. The composition of this alloy is balanced to provide a unique combination of very high strength, together with good toughness, ductility, and resistance to fatigue.
