In this article, the addition of nitrogen to duplex stainless steel weld metal has been achieved and the resultant weld metals have been assessed for their microstructural features and corrosion behaviour.Abstract:
The addition of nitrogen to duplex stainless steel weld metal has been achieved and the resultant weld metals have been assessed for their microstructural features and corrosion behaviour. It was found that, although autogenous welding of duplex stainless steels is not recommended, the addition of nitrogen through the shielding gas mixture can help to obtain quality welds with the desired phase balance and corrosion resistance.read more

The effect of alloyed nitrogen or dissolved nitrate ions on the anodic behaviour of austenitic stainless steel in hydrochloric acid
Roger C. Newman,T. Shahrabi +1 more
TL;DR: In this article, the anodic behavior of high purity stainless steels based on a 316L composition was studied at room temperature in HCl solutions from 1 to 6 M. The effect of 0.22% nitrogen has little or no effect on the active dissolution kinetics at low overpotentials.
