  • Patent number: 5485641
    Abstract: A composite, non-electrically conductive, non-sparking, non-magnetic and lightweight cutter/plier hand tool has two pivotally interconnected lever members, each of unitary, one-piece construction and formed by compression molding of multiple plies of a discontinuous random glass fiber-reinforced plastic sheet molding compound. Fixed to the jaw of each lever member is a ceramic insert made of transformation toughened zirconia, formed by dry compression and then sintering of a powdered form of the ceramic material. Each insert has a serrated gripping portion and a cutting portion, with cutting surfaces on the opposed inserts operating in shearing relationship. Three versions of the inserts are disclosed.

  • Patent number: 4152148
    Abstract: Welding composition for welding a compatible steel having exceptionally high strength and high fracture toughness, which consist essentially of iron containing respective percents by weight of constituents as follows: 0.12-0.20 carbon, 1.8-2.2 chromium, 0.9-1.1 molybdenum, 12.0-14.5 cobalt, 9.0-10.5 nickel and a deoxidizer selected from the class consisting of (a) 0.05-0.20 manganese, (b) 0.010-0.035 aluminum, (c) 0.01-0.20 silicon, (d) a combination selected from among (a), (b), and (c), and (e) a combination selected from among (a), (b), and (c) and 0.02-0.10 vanadium; the composition having a concentration of respective constituents adjusted to have an ultimate tensile strength of 210-250 Ksi (thousands of pounds per square inch), a tensile yield strength of 200-230 Ksi and a Charpy V-Notch absorbed energy of at least 30 foot pounds and produce a weldment having satisfactory strength, toughness, and stress corrosion resistance.

  • Patent number: 4076525
    Abstract: A weldable alloy steel having improved fracture toughness and stress corrosion resistance at very high strength levels in which the essential composition, according to percent by weight is in the range of 0.12 - 0.17% carbon, 1.8 - 3.2% chromium, 0.9 - 1.35% molybdenum, 11.5 - 14.5% cobalt, and 9.5 - 10.5% nickel, the remainder being substantially iron, i.e., with minor amounts of certain impurities and residual elements. Very good stress corrosion resistance and fracture toughness at high strength levels is produced when these elements are alloyed in the percent by weight ranges of 0.15 - 0.17% carbon, 1.8 - 2.2% chromium, 0.9 - 1.1% molybdenum, 13.5 - 14.5% cobalt, and 9.5 - 10.5% nickel. Good fatigue endurance is achieved. Minor amounts of manganese also may be present.
