  • Patent number: 4042383
    Abstract: An alloy particularly directed to use as a wrought filler metal and contains certain percentages of chromium, iron, boron, molybdenum, nickel and optionally carbon, manganese and silicon.
    Type: Grant
    Filed: May 17, 1976
    Date of Patent: August 16, 1977
    Assignee: The International Nickel Company, Inc.
    Inventors: Walter Adrian Petersen, Robin Mackay Forbes Jones
  • Patent number: 4016008
    Abstract: A method for producing high strength composite tubing having a corrosion-resistant metal lining. The composite tubing is prepared by extrusion of an assembly having a low alloy steel outer shell and metal powder lining. The metal powder is consolidated during extrusion and high strength is attained by heat treatment.
    Type: Grant
    Filed: July 31, 1975
    Date of Patent: April 5, 1977
    Assignee: The International Nickel Company, Inc.
    Inventors: Robin Mackay Forbes Jones, Walter Adrian Petersen
  • Patent number: 4012227
    Abstract: A highly-castable, ductile, corrosion-resistant and weldable stainless steel intended for exposure in marine environments. A highly satisfactory composition of the alloy is 24% Ni, 24% Cr, 4% Mo, 2% Si, 0.2% B and balance iron.
    Type: Grant
    Filed: June 19, 1975
    Date of Patent: March 15, 1977
    Assignee: The International Nickel Company, Inc.
    Inventors: Robin Mackay Forbes Jones, Walter Adrian Petersen
  • Patent number: 4010309
    Abstract: Directed to a welding flux and covered welding electrodes, and, more particularly, to covered electrodes having a nickel-chromium-iron alloy core and a special flux coating or covering, which electrode is capable of joining similar and dissimilar metals and which produces, in all positions, sound welds free from cracking and porosity and deposits having excellent corrosion resistance.
    Type: Grant
    Filed: October 30, 1975
    Date of Patent: March 1, 1977
    Assignee: The International Nickel Company, Inc.
    Inventor: Walter Adrian Petersen
  • Patent number: 3984239
    Abstract: An alloy particularly suited for use as an inert gas shielded-arc filler metal containing 28% to 35% chromium, 13% to 18% iron, 2.8% to 4.2% aluminum, 0.1% to 3.8% manganese, up to 0.2% silicon, 0.3% to 0.8% titanium, 0.04% to 0.15% carbon and the balance essentially nickel. The filler provides the capability for making substantially defect-free welds in heavy section thicknesses that have excellent elevated temperature carburization resistance and strength.
