Explanation: Coincido con Carole; pero según el contexto, si no estás explicando el proceso en sí, tal vez la inclusión de la palabra "process" te resulte redundante en inglés, y te convenga "pickling" solo.
Aquí tienes la definición, y un ejemplo con tu mismo contexto.
Pickling: Treating the surface of iron or steel with acid to remove scale, rust and dirt, preparatory to further processing such as cold rolling, tinning, galvanizing, polishing, etc http://www.amm.com/ref/glossary.HTM
