Document Type and Number:

Japanese Patent JP6396574

Kind Code:

B2

Abstract:

A welding filler metal or a welding filler metal product having, in weight percent: 17.0-23.0% chromium, 5.0-12.0% molybdenum, 3.0-11.0% tungsten, 3.0-5.0% niobium, 0-2.0% tantalum, 1.2-3.0% titanium, 0.005-1.50% aluminum, 0.0005-0.100% carbon, <2.0% iron, <5.0% cobalt, and balance nickel wherein the nickel is 56.0-65.0%. A weld deposit formed from the welding filler metal has a minimum yield strength in the as-welded condition of at least 72 ksi (496 MPa). Also, a weld deposit and a method of forming a weld deposit comprising, in weight percent: 17.0-23.0% chromium, 5.0-12.0% molybdenum, 3.0-11.0% tungsten, 3.0-5.0% niobium, 0-2.0% tantalum, 1.2-3.0% titanium, 0.005-1.50% aluminum, 0.0005-0.100% carbon, <8.0% iron, <5.0% cobalt, and balance nickel wherein the nickel is 56.0-65.0%. The weld deposit has a minimum yield strength in the as-welded condition of at least 72 ksi (496 MPa).
