摘要： A tin-plated stainless steel sheet which has a tin plating layer having good adhesion to a stainless steel sheet and exhibits excellent whisker resistance in various environments, and wherein a nickel plating layer having a thickness of 0.3-3 µm is formed on a stainless steel sheet, and a tin plating layer having a thickness of 0.3-5 µm is formed on the nickel plating layer. This tin-plated stainless steel sheet is characterized in that nickel crystals in the nickel plating layer have a lattice distortion of 0.5% or less.

摘要： A connecting component material used as a material constituting a connecting component, wherein the connecting component material is obtained by using a Ni-plated metal plate in which a Ni plating layer is formed on the surface of a metal plate, and the average depth (R) of a surface roughness motif in at least one direction on the surface of the Ni plating layer is 1.0 µm or above, and by forming a Sn plating layer having a thickness of 0.3 to 5 µm on the Ni plating layer of the Ni-plated metal plate; the connection component material makes it possible to reduce friction and minimize abrasion of the material when a connecting component such as an electrical connection terminal is fitted, and to improve the reliability of a stable electrical connection; and the connecting component material can be used in e.g., electrical contact components such as lead frames, harness plugs, and connectors used in electrical and electronic devices and the like.
