Abstract (en)
[origin: US2014161658A1] A precipitation hardenable, martensitic stainless steel alloy is disclosed. The alloy has the following composition in weight percent, about C 0.03 max Mn 1.0 max Si 0.75 max P 0.040 max S 0.020 max Cr 10-13 Ni 10.5-11.6 Mo 0.25-1.5 Co 0.5-1.5 Cu 0.75 max Ti 1.5-1.8 Al 0.3-0.8 Nb 0.3-0.8 B 0.010 max N 0.030 max The balance is iron and usual impurities. The disclosed alloy provides a unique combination of corrosion resistance, strength, and toughness.
