摘要： A method for manufacturing a molded member includes carrying out a multi-stage drawing process and at least one finishing ironing process on a base metal sheet, the molded member including a tubular body and a flange formed at an end portion of the body. The multi-stage drawing process includes a preliminary drawing process for forming a preliminary body having a body element from the base metal sheet, and a plurality of compression drawing processes performed after the preliminary drawing process, the compression drawing processes drawing the body element while applying compressive force along a depth direction of the body element to a circumferential wall of the body element. The at least one finishing ironing process is carried out such that a mold clearance of an upper portion of the body element is narrower than a mold clearance of a lower portion of the body element.

An embodiment of the present invention provides a stainless steel material for a diffusion bonding jig having excellent deformation suppressibility and releasability, the material being a stainless steel material including 1.5 mass % or more of Si, and a ratio (Fr/Fp) of the high-temperature strength (Fr) of the stainless steel material at 1000° C. to the high-temperature strength (Fp) of a bonding member at 1000° C. being 0.9 or more, the bonding member to be bonded by diffusion bonding. The stainless steel material preferably includes C: 0.1 mass % or less, Si: 1.5 to 5.0 mass %, Mn: 2.5 mass % or less, P: 0.06 mass % or less, S: 0.02 mass % or less, Ni: 8.0 to 15.0 mass %, Cr: 13.0 to 23.0 mass %, and N: 0.2 mass % or less.

摘要： A composite twisted wire (1) which is obtained by twisting a plurality of strands. This composite twisted wire (1) includes: an aluminum-covered strand (2) that is obtained by forming a coating film (2b), which is formed of aluminum or an aluminum alloy, on the surface of a steel wire (2a); and an aluminum wire (3) that is formed of aluminum or an aluminum alloy. This composite twisted wire is reduced in weight, while exhibiting excellent tensile strength and excellent long-term stability with respect to electrical resistance. Consequently, this composite twisted wire is suitable, for example, for use as a wire harness of automobiles.

摘要： A metal roofing member 1 has a front substrate 10, a rear substrate 11 and a core material 12. The front substrate 10 is made of a metal sheet. In the front substrate 10, a box-shaped body portion 100 and a flange portion 110 extending from the body portion 100 are provided. The flange portion 110 is formed by folding back, over the rear side of the front substrate 10, of a metal sheet 111 extending outwards of the body portion 100 in a direction 100b perpendicular to a height direction 100a of the body portion 100, from a lower edge of the body portion 100, in such a manner that the metal sheet 111 wraps around the rear substrate 11. The metal roofing member 1 is disposed on a roof base, with the flange portion 110 butting against a flange portion 110 of another metal roofing member.
