  • Alloys for high creep applications
    Patent number: 3954421
    Abstract: There is disclosed a ferritic alloy having a high creep resistance particularly suitable for use in the castings, the welding material, and welds of the casings and conductors of apparatus operating at high temperatures, typically steam turbines operating at about 1050.degree.F. This alloy has between about 1% and 2% copper and small but effective quantities of carbon, vanadium, and molybdenum and is low in manganese, silicon, and nickel although nickel is sometimes needed for increased tensile strength and toughness. In modifications or variations of this alloy small but effective quantities of cobalt and tungsten improve creep resistance while chromium is minimized.
