The Ferroxyl test is designed to determine whether austenitic stainless steel needs to be pickled or whether it has been pickled satisfactorily. When structure on the surface of austenitic stainless steel has not been evenly restored, an excess of metallic iron will be present (so called embedded iron) which will adversely affect the properties of the stainless steel.
The presence of embedded iron in the stainless steel surface disturbs the chromium oxide film reducing the corrosion resistance locally. When embedded iron is not removed serious (pit) corrosion may set in.
Experimental Principle ::: ---
The test is based on a reaction of potassium ferricyandide with iron in a strongly acid medium. The excess iron dissolves in this strongly acid medium as ferrous ion to form a blue complex, known as Prussian Blue.
When during this test this blue coloration manifests itself it means that the surface of the stainless steel does not yet have the correct structure and has been insufficiently picked.
