摘要： A process and apparatus for pickling the surface of stainless steel strip feeds the stainless steel strip through a plurality of pickling tanks containing a hydrochloric acid pickling acid. The pickling acid bath is maintained at a temperature of at least about 40° C. An oxidizing agent is added to the acid solution in an amount to maintain at least about one third and preferably at least about half of the soluble iron in the form of ferric chloride based on the total amount of iron in the acid solution.
