Bohler 88073 Avesta 302 Pickling Bath 16 Litres (44 Lbs) Concentrate (Mix 3:1)
Avesta Pickling Bath 302 is a concentrate that should be diluted with water depending on the stainless steel grade.
The pickling bath restores stainless steel surfaces that have been damaged during fabrication operations such as welding, forming, cutting and blasting. It removes weld oxides, the underlying chromium-depleted layer and other defects that may cause local corrosion. Avesta Pickling Bath 302 is recommended for immersion pickling of small objects and for pickling surfaces that are time-consuming to brush or spray pickle. It can also be used for circulation pickling of pipe systems.
Standard grades, such as 304 and 316: Mix 1 part 302 into 3 parts of water. A further dilution can be done if longer pickling times can be accepted. High alloyed grades, such as duplex grades (2205) and austenitic grades (904 L) for use in severe corrosive conditions: Mix 1 part of 302 into 2 parts of water.
