    Abstract: An alloy includes a composition, in weight percent, of aluminum from about 1.3% to about 1.8%, cobalt from about 1.5% to about 4.0%, chromium from about 18.0% to about 22.0%, iron from about 4.0% to about 10.0%, molybdenum from about 1.0% to about 3.0%, niobium from about 1.0% to about 2.5%, titanium from about 1.3% to about 1.8%, tungsten from about 0.8% to about 1.2%, carbon from about 0.01% to about 0.08%, and balance nickel and incidental impurities. The alloy has a stress rupture life at 700° C. and 393.7 MPa (57.1 ksi) of at least 300 hours and a room temperature percent elongation of at least 15% after aging at 700° C. for 1,000 hours.

    Abstract: Nickel-base precipitation hardenable alloys with enhanced hydrogen embrittlement resistance and desired yield strength have critical ranges of titanium and iron, among other elements. One of the nickel-base precipitation hardenable alloys has a composition, in wt.%, of Cr from about 18.0% to about 23.0%, Fe from about 7.0% to about 12.0%, Mo from about 6.5% to about 9.5%, Nb from about 3.2% to about 5.2%, Ti from about 0.3% to about 1.3%, Al up to about 0.4%, with a balance of Ni and incidental impurities. This alloy has a yield strength (0.2% offset) greater than or equal to 120 ksi (827 MPa), a plastic strain ratio greater than or equal to 0.35, and a plastic strain to failure greater than or equal to 9.0%.

    Abstract: A welding filler metal includes, by weight percent: chromium of at least 28.0% and at most 31.5%; niobium of at least 0.60%; tantalum of at least 0.010%; molybdenum of at least 1.0% and at most 7.0%; carbon of at least 0.040% and at most 0.09%; manganese of at most 1.0%; balance nickel and inevitable impurities, wherein the sum of niobium and tantalum is at least 2.2% and at most 4.0%. A welding filler metal consumable is made from the welding filler metal. A welding deposit is formed from the welding filler metal consumable. A weldment is formed using the welding filler metal consumable.
