Abstract:
PURPOSE: To provide a ferritic stainless steel excellent in surface glossiness and having use for a decorative material such as a building material.
CONSTITUTION: A ferritic stainless steel is electropolished at 90-160°C and 100-500A/dm2 current density with the steel as an anode in a soln. contg., by weight, 20-80% phosphoric acid, 20-70% sulfuric acid and 10-20% water and contg. 0.5-100g/l potassium bichromate.
