Latest Patents
Kohno's latest patents include a method for producing chromium-containing hot rolled steel strips. This invention provides hot-rolled steel strips that can be directly used after acid-pickling, featuring no Cr-decreasing layer and no shot blasted marks on their surface, while also ensuring good corrosion resistance. The technique involves hot-rolling a steel slab with a chromium content of 6.0 to 25.0 wt. %, coiling it at a temperature not exceeding 700°C, and optionally quenching it in water. Following this, the strips undergo annealing in a reducing atmosphere and acid-pickling in a nitric acid/hydrochloric acid solution.
Another notable patent is the method of making austenitic stainless steel sheets. This method produces hot-rolled steel sheets with superior surface appearance, free of surface patterns and uneven glossiness. The process involves using an austenitic stainless steel slab containing specific percentages of copper, vanadium, and molybdenum, and includes various steps such as pickling in a nitric-hydrofluoric acid solution and electrolyzing during finishing pickling.
