Pickling gel for AISI 300 series stainless steel. - strong Pickling is the basic treatment to eliminate traces of oxide due to thermal changes. Pickling is not a simple aesthetic action that serves to remove the 'black of the weld'. In fact, good pickling has the task of removing the depleted chromium layer due to thermal alteration, a critical area for corrosive attack as it is unprotected. Only as a side effect bleach the weld. WE DEK 125 GEL is a pickling gel for stainless steel 300 series excluding AISI 303. It allows the pickling of both weld-only strokes and the entire surface.
