What's the reason for the strip after pickling?
Will it use a strong acid wash, and the temperature is too high to destroy the ductility of steel?.
Pickling is only surface rust removal, which will not affect the hardness of the material.
I suggest you try phosphoric acid and BW-500P phosphoric acid fast acid cleaning lotion, pickling process. Without heating, rust will soon. And renewable recycling. The cost is much lower than that of hydrochloric acid.
