Subcontract electropolishing

Calamo undertakes subcontract electropolishing of almost any stainless steel component. We have several units for subcontract electropolishing, the largest containing 40,000 litres of electrolyte, which means that we have capacity for very large items.


Pickling is used in applications with high demands on metallurgical cleanliness, sterility and hygiene within the following areas:


An electropolished surface is easier to clean and sterilize, thanks to the smoothness, reduced surface and lack of inclusions and surface defects.
It creates an appealing exterior to the items.

We can electropolish all austenitic, ferritic and austenitic-ferritic (Duplex) steel grades.
