Chromium nitrides in Duplex stainless steels

Chromium nitrides in the Duplex steels are a relevant detrimental chemical compound that affect fragility and pitting corrosion due to the reduction of Chromium inside the solution. The images show how important is the metallographic etching stage, because a generic etching does not enable the evaluation of the chromium nitrides. The metallographic ability and know-how of a laboratory is fundamental during the quality control and R&D stages.
