Abstract: A steel wire is formed of a steel containing: not less than 0.6 mass % and not more than 0.7 mass % carbon, not less than 1.2 mass % and not more than 2.1 mass % silicon, not less than 0.2 mass % and not more than 0.6 mass % manganese, not less than 1.4 mass % and not more than 2 mass % chromium, and not less than 0.15 mass % and not more than 0.3 mass % vanadium, with the balance being iron and unavoidable impurities. The steel includes a matrix made up of tempered martensite, and a non-metallic inclusion present in the matrix. When ?area of the non-metallic inclusion is represented as H1 and ?area of a region including both the non-metallic inclusion and a decreased-hardness portion is represented as H2, a ratio of H2 to H1, or, H2/H1 is at least 1 and less than 1.3.

Abstract: A strand for a wiring harness includes a first element wire and a second element wire twisted around the first element wire and made of copper or a copper alloy. The first element wire includes a core portion made of stainless steel and a covering layer covering the core portion and made of copper or a copper alloy.

Abstract: An object of the present invention is to improve machining speed by realizing both conductive properties and discharge performance with regard to an electrode wire for wire electric discharge machining, the electrode wire being obtained by plating a steel wire with a copper-zinc alloy. Another object is to suppress the occurrence of separation, cracking, and the like of plating in a wire-drawing step of an electrode wire. An electrode wire for wire electric discharge machining of the present invention includes a steel wire (11) serving as a core wire, and a plating layer (12) that covers the steel wire and that is composed of a copper-zinc alloy, in which an average zinc concentration of the plating layer is 60% to 75% by mass, a conductivity of the plating layer is 10% to 20% IACS, and a wire diameter is 30 to 200 ?m.

Abstract: Reinforcement devices (10, 10′, 110, 110′) may be inserted into a cavity (6) of a hollow structural member (1) in order to reinforce the hollow structural member (1). The reinforcement devices (10, 10′, 110, 110′) may include a first elongated reinforcement part (11, 111) having at least one mating surface (15a, 17a, 115a) extending along a longitudinal axis of the first part (11, 111) and a second elongated reinforcement part (12, 121) having at least one mating surface (25a, 27a, 125a) extending along a longitudinal axis of the second part (12, 121). An adhesive resin material preferably adheres the first elongated reinforcement part (11, 111) to the second elongated reinforcement part (12, 121). The adhesive resin material may comprise a thermosetting resin that thermosets when heated. Thus, a thermoset product (31, 136) will connect the reinforcement parts (11, 12, 111, 121) after heating.
