  • Enhanced machinability precipitation-hardenable stainless steel for critical applications
    Patent number: 6576186
    Abstract: A precipitation-hardenable, martensitic stainless steel alloy is described having the following composition in weight percent. C 0.030 max. Mn 1.00 max. Si 1.00 max. P 0.030 max. S 0.005-0.015 Cr 14.00-15.50 Ni 3.50-5.50 Mo 1.00 max. Cu 2.50-4.50 Nb + Ta (5 × C)-0.30 Al 0.05 max. B 0.010 max. N 0.030 max. and the balance is essentially iron and the usual impurities. The alloy provides a unique combination of properties in that useful articles made therefrom provide superior machining characteristics relative to known high strength 15Cr-5Ni precipitation-hardenable stainless steel alloys, while meeting the strength, ductility, and hardness requirements specified in AMS 5659 for critical applications.
