ABSTRACT:
A precipitation hardenable martensitic stainless steel that includes, in percent by weight, 11.0 to 12.5 percent chromium, 1.0 to 2.5 percent molybdenum, 0.15 to 0.5 percent titanium, 0.7 to 1.5 percent aluminum, 0.5 to 2.5 percent copper, 9.0 to 11.0 percent nickel, up to 0.02 percent carbon, up to 2.0 percent tungsten, and up to 0.001 percent boron. Articles formed from the stainless steel and methods of forming the same are also disclosed.
