    摘要: Provided is a method of forming a locking ridge for a case of forming the locking ridge on an outer peripheral surface of a joint portion by form rolling, the method realizing a joint portion structure which is superior in pipe detachment prevention performance when pipes with locking ridges are connected by fixing pipe ends with a housing. Using a convex roller arranged inside the workpiece pipe body and a forming circular groove arranged outside the pipe body, the locking ridge is form-rolled such that an upright wall portion thereof is raised at an angle of at least 65° and no greater than 90° with respect to the outer peripheral surface in the pipe axis direction, and that a height of the locking ridge from the outer peripheral surface to the apex of the tip portion is at least a total of curvature radii of faces of the processing means in contact with the pipe body.

    摘要: Provided is a clad steel plate with excellent thermal conductivity that can be used suitably in cookware and the like. The present invention is a three-layer clad steel plate having a carbon steel base material and stainless steel mating material disposed respectively on both surface sides of the base material, wherein a plate thickness ratio L given by Equation (1) is 1.0 - 5.0 and at least one surface of the clad steel plate has a plurality of protrusions and recesses. Plate thickness ratio L = the plate thickness of the base material / the total thickness of the mating material ... Equation (1) Here, the base material thickness and the mating material thickness are the thicknesses at the protrusions.
