If we talk about sanitary applications, then it is important to design measuring instrumentation properly. It is also important to make sure that irregularities are not present after the production process so it requires doing the stainless steel cleaning with hard agents and sterilization.
Another important thing is to look for the quality of the surface finish that comes directly in contact with the process and cleaning agents. A smooth stainless steel can also prevent corrosion, and may also prevent the growth of bioburden.
Electropolishing Stainless Steel
Electropolishing is an industrial method to clean and smooth the stainless steel surfaces. It is also used to reduce the roughness that can affect the stainless steel.
Electropolishing process is performed on the principle of electrolysis. The essential things required in electropolishing process is the current, sulphuric acid solution and an orthophosphoric as an electrolyte.
The process of electropolishing stainless steel does not take much time. It usually takes just a few minutes and a maximum of 20-25 minutes. The duration of time depends on the quantity and shape of the end result.
Some Advantages of Electropolished Surfaces
Electropolishing stainless steel process involves to remove the layer, this results in a smoother surface that can be easily cleaned and is free of impurities that may increase corrosion, fissures, and deposits.
Electropolishing process can also eliminate free iron from the surface of stainless steel. Electropolishing process results in the surface which is full in nickel and chromium.
An electropolished surface increases cleanliness right down to a microscopic level. Instrumentation made out of electropolished stainless is the option for sanitary applications that require any process where hygienic conditions are the must.

This smoother surface also decreases the locations that can contaminate another process batch unless the residue is removed.
