  • Patent number: 7252249
    Abstract: A solenoid-type fuel injector assembly having at least one component formed of stabilized, solenoid-quality ferritic stainless steel. In a preferred embodiment, an austenitic fuel tube is laser-welded to an injector body and to a solenoid pole piece formed of the subject material. The stabilized, solenoid-quality ferritic stainless steel, preferably a free-machining grade thereof, comprises from about 10% to about 35% chromium, and at least one stabilizing element selected from the group consisting of titanium and columbium. Components thus formed are weldable, exhibit soft magnetic properties sufficiently strong for carrying a magnetic flux in a solenoid pole piece, have desired structural and mechanical properties, and reduce the susceptibility of a solenoid-type fuel injector to metallurgical sensitization and intergranular corrosive attack at weld sites.

  • Patent number: 6520432
    Abstract: A process of laser welding high carbon martensitic stainless steel components and austenitic stainless steel components by a stabilized ferritic stainless steel fusion zone modifier in the weld joint, and articles formed therefrom. The stabilized ferritic stainless steel fusion zone modifier comprises, in terms of weight percentage, from about 10% to about 35% chromium, and at least one element selected from the group consisting of no more than about 1.5% titanium and no more than about 1.5% columbium. The stabilized ferritic stainless steel fusion zone modifier present in the fusion zone inhibits and prevents solidification cracks and micro-fissures from forming in the weld joint, and assists immunity to environmental degradation.

  • Patent number: 3974914
    Abstract: A package for a roll of continuous sheet material is shown having a first hollow circular core on which the sheet material is wound with a tube within the core. The tube is of greater length than the core so that the ends thereof extend beyond the continuous roll. End plates are provided on opposite ends of the roll and are apertured for receiving the extending sections of the tube. The end plates support the roll so that when two of such rolls, with associated apparatus are stacked, the end plates bear any loading force associated with the stacking. The end plates, the core, the tube and the roll of material are secured in a unitary structure by fasteners attached to the opposing ends of the second tube. A hollow covering member open at both ends is placed over the roll.
