Post-fabrication surface treatment of stainless steels

Post-fabrication surface treatment of stainless steels. Why surface finishing is important. Stainless steel is shielded from the environment by a thin, protec- tive and invisible surface layer – the passive film – that consists mainly of chromium oxide.

What surface finishes are available on stainless steels?

The importance of surface finish in determining the corrosion resistance of the stainless steel surface cannot be overemphasised. A rough surface finish can effectively lower the corrosion resistance to that of a lower grade of stainless steel. The European standards for stainless steels have attempted to define the most common surface finishes.
