Zusammenfassung:	PURPOSE:To provide the descaled stainless steel strip having brightness without entailing a high-temp. treatment. CONSTITUTION:An annealed stainless steel strip 1 is subjected to an electrolytic treatment in an aq. neutral salt soln. electrolytic tank 2 and is subjected to an immersion treatment in an aq. alkaline soln. immersion tank 6. The stainless steel strip is then subjected to an immersion treatment in an aq. nitric acid/ hyclrofluoric acid mixed soln. immersion tank 10. The electrolytic treatment in the aq. neutral salt soln. electrolytic tank 2 and the immersion treatment in the aq. alkaline soln. immersion tank 6 may be alternated in order.
