Materials, methods and techniques relate to steel alloys. In some instances, steel alloys can include chromium, molybdenum, vanadium, copper, nickel, manganese, niobium, aluminum, and iron. In some instances, exemplary steel alloys are subjected to solution carburizing, tempering, and/or plasma nitriding. Exemplary steel alloys are typically precipitation strengthened carburizable and nitridable steel alloys.

Precipitation strengthened carburizable and nitridable steel alloys

Exemplary alloys may comprise, by weight percentage, 13.25% to 14.75% chromium; 4.5% to 5.5% nickel; 0.11% to 0.17% carbon; 0.01% to 0.31% titanium; and the balance of weight percent comprising iron and incidental elements and impurities. Exemplary methods may include conducting additive manufacturing with an atomized alloy powder to generate a manufactured article, where the atomized alloy powder may comprise, by weight percentage, 13.25% to 14.75% chromium; 4.5% to 5.5% nickel; 0.11% to 0.17% carbon; 0.01% to 0.31% titanium; and the balance of weight percent comprising iron and incidental elements and impurities.

Stainless steel powders for additive manufacturing

Exemplary martensitic steel alloys may be particularly suited for additive manufacturing applications. Exemplary atomized alloy powders usable in additive manufacturing may include carbon, nickel, manganese, chromium, and the balance iron and incidental impurities. Exemplary steel alloys can be molybdenum free.

Auto-tempering steels for additive manufacturing

Complex concentrated alloys include five or more elements, at least one of which is ruthenium. Example complex concentrated alloys can include nickel and chromium, iron, ruthenium, molybdenum, and/or tungsten. Example complex concentrated alloys have single phase microstructure of face centered cubic (FCC) and can be homogenous. Example complex concentrated alloys can exhibit improved corrosion resistance.
