  • Patent number: 10625321
    Abstract: According to the present invention, there is provided a cooling apparatus for a steel material in which one portion in a longitudinal direction of an elongated steel material (10) is heated while the steel material is fed in the longitudinal direction in a state where one end portion of the steel material is gripped, and the one end portion is moved in a two-dimensional or three-dimensional direction so as to form the steel material into a predetermined shape including a bent portion and thereafter to cool a heated portion including the bent portion. The cooling apparatus includes a first cooling apparatus (22) that ejects a first cooling medium to the heated portion, and a second cooling apparatus (23) that is disposed on a downstream side from the first cooling apparatus when viewed along a feeding direction of the steel material, and that ejects a second cooling medium to the heated portion.

  • Publication number: 20180034070
    Abstract: A stainless steel sheet used for a separator of a polymer electrolyte fuel cell, wherein the steel sheet has a volume ratio of M2B boride-based metal precipitates of 8% or higher and a volumetric-basis particle-size frequency distribution of M2B boride-based metal precipitates having sphere-equivalent diameters of 6.72 ?m or less of 99.5% or higher, in a surface layer which has a depth of 0.2 t from at least one of surfaces (t is an overall thickness of the steel sheet), and the steel sheet has an apparent density of 0.995 or higher, assuming a real density to be 1. A polymer electrolyte fuel cell in which the stainless steel sheet is used for a separator is given an excellent cell performance without high-cost surface treatment such as expensive gold plating for the reduction of the contact resistance of a surface.
