      can any one guide me how to make scratch resistant polished surface in AISI 316L material as we are using them for a art work...

      What are you talking about doing? Modifying the material properties to improve scratch resistance or apply a coating to the surface that is scratch resistant?

      the aim is to achieve scratch resistance by hardening the surface..but what kind of hardening?
      if the coat is transparent enough we can go for coating solution also...

      yes we have done electro polishing but the surface finish is not satisfactory as we require almost mirror like finish

      If it is sheet you are working with - it comes with a "protective coating" in the form of a peel off plastic sheet - which if handled carefully when plasma or water jet cutting - will provide some protection from scratches whilst on the bed of the machine. Subsequent minor hand polishing should bring it back to a visually very nice looking surface finish.

      If it is machined parts you are working with - well they shouldn't have scratches on them - if they have been handled properly.

      To remove scratches requires some "physical effort" - with buffing and polishing and the link below provides some information on the ways to do that for different scenarios.

      Hope this is of help to you.
