Nital Etch

Nital etching is a non-destructive testing method that uses chemical etching of a substrate surface to find visual indications, typically related to aggressive grinding or machining of steels.  Nital etching of these components can reveal these defects and determine the steps required to remediate these defects.

Sinto Surface Technologies has these capabilities in-house at our Bedford Heights plant through a local partner and can partner with local approved sources at our other locations to provide this service.   As Nital Etching typically precedes other surface modification processes, this can allow us to bundle capabilities to provide one-stop-shop services.


  • Aerospace approved Nital Etch processing of steels for aerospace and industrial applications
  • Convenient local or on-site processing of components
  • Allows for “One Purchase Order” approach to surface processing needs
