摘要： Provided is a threaded joint for a pipe in which scalability, compression resistance, and galling resistance are enhanced. Specifically, a pin nose outer peripheral surface forms an outward convex curve in an axial cross-sectional view; the convex curve is such that a composite R curve, in which a plurality of outward convex arcs having different radiuses of curvature are connected in sequence to a generating line of a cylindrical portion next to a male member, is curved such that the radiuses of curvature increase with distance from the male member and tangents on connection points of the arcs are aligned with those of corresponding arcs connected thereto; and the inner peripheral surface of a box component facing the pin nose is a tapered surface that interferes with the pin nose outer peripheral surface when connected to a pin component.

摘要： The present invention provides a composite roll for cold rolling capable of rolling a cold-rolled steel strip having little edge drop, a cold-rolled stainless steel strip or a bright finish steel strip having excellent surface brightness or a silicon steel strip excellent in magnetic properties without causing breakage of roll, which is a roll in which a sleeve is fitted at a surrounding of a shaft portion with the shaft portion as a central axis and its fabrication method, in which the sleeve is constituted by previously integrating a plurality of pieces of mold members divided by a face intersecting with the central axis of the roll. Further, this is a fit roll in which a sleeve member of an outermost layer is made of WC—Co series hard alloys having Young's modulus of 35000 kgf/mm or more and Co content of 12-50 weight % and is provided with a wall thickness of 3% or more of roll radius and a ratio L/D of a length L of a barrel of the sleeve to a diameter D of the roll falls in a range of 2-10. Further, when there are one layer or more of intermediate layers between the outermost layer of the sleeve and the shaft core, the intermediate layers are arranged such that Young's modulus of the layer on the outer side is larger than Young's modulus of the layer on the inner side.

摘要： A method enhances fatigue strength of ear portions which are high fatigue risk parts in a torsion beam almost without bringing about disadvantages in terms of productivity and cost. A torsion beam is formed with a portion of the tubular body into an approximately U-shape in cross section by crushing the portion of the tubular body in the radial direction and, thereafter, due to bending with a bottom line set as a belly side of bending, a bending strain of 2 to 6% in the tube longitudinal direction on a tensile side is imparted to the ear portions.

摘要： A method of producing a stainless steel produces steel sheets having excellent surface brightness. The method includes performing a cold rolling operation using a work roll having a Young's modulus between 25,000 to 70,000 kg/mm.sup.2 in one or more stands of a tandem mill having a plurality of stands. Preferably the work roll is composed of a tungsten carbide based hard metal alloy. The diameter of a work roll at a final stand of the tandem mill is equal to or smaller than a diameter of a work roll in the previous stand. It is preferable that the work roll is dimensioned to have a diameter between 150 mm to 400 mm. In addition, it is preferable that a cold rolling operation is achieved at a reduction between 25% to 60% reduction in the final stand of the tandem mill.
