MANUFACTURING METHOD OF STAINLESS-STEEL PROCESSED PRODUCT WITH FINGERPRINTS INCONSPICUOUS

To provide a manufacturing method of a stainless-steel processed product with excellent fingerprint resistance, which has no color unevenness on a surface.SOLUTION: A manufacturing method of a stainless-steel processed product having an uneven surface formed on a surface, comprises: a sandblast treatment step of forming the uneven surface on the surface of the stainless-steel processed product by spraying a mixture of an abrasive material and compressed-air to the surface of the stainless-steel processed product; an electrolytically cleaning treatment step of electrolytically cleaning the sandblasted stainless-steel processed product in an electrolytic cleaning agent; and an electrolytically polishing treatment step of electrolytically polishing the surface of the stainless-steel processed product that is electrolytically cleaned. A colored stainless-steel processed product can be manufactured by performing a coloring treatment and a curing treatment.SELECTED DRAWING: Figure 2 【課題】耐指紋性に優れ、かつ表面の色むらがないステンレス加工品の製造方法を提供する。【解決手段】研削材と圧縮空気の混合物をステンレス加工品表面に吹き付けることにより、前記ステンレス加工品表面に凹凸面を形成するサンドブラスト処理工程、サンドブラスト処理されたステンレス加工品を電解洗浄剤中で電解洗浄を行う電解洗浄処理工程、電解洗浄処理されたステンレス加工品表面を電解研磨する電解研磨処理工程、とからなることを特徴とする表面に凹凸面が形成されたステンレス加工品の製造方法である。発色処理及び硬化処理を行うことにより発色ステンレス加工品も製造できる。【選択図】図２
