Passivation of austenitic and martensitic stainless steels
Passivation is a chemical process resulting from the formation of a surface layer of a non-friable and homogeneous oxide on the surface of a metal.
Aluminum, titanium, cobalt chromium, stainless steels allow the formation of such a passive layer that protects the substrate.
Thanks to the know-how of our R&D team and in collaboration with Cetim, NGL has been able to develop an efficient and controlled passivation process on austenitic and martensitic steels, based on citric acid, without CMR compounds, whose composition complies with the requirements of regulation EU2017/745.
