  • Publication number: 20240044014
    Abstract: The problem of the present invention is to provide a roughening treatment method in which the surface of stainless steel is sufficiently roughened in an efficient manner with few steps, while maintaining good surface quality of the stainless steel after treatment. The above problem is solved by a roughening treatment method for stainless steel, which comprises a roughening treatment step that uses a first aqueous composition, and a post-treatment step that uses a second aqueous composition. Namely, the roughening treatment step is to roughen the surface of stainless steel containing copper or a metal having an ionization tendency larger than copper by bringing the first aqueous composition into contact with the surface, wherein the first aqueous composition comprises 0.1% to 20% by mass of hydrogen peroxide based on the total amount of the first aqueous composition, 0.
