Summary: With increasing use of high nitrogen steels it is necessary to precisely quantify the nitrogen content to attain beneficial mechanical properties and corrosion resistance. High nitrogen contents partition into interstitial nitrogen and transition metal nitrides in austenitic stainless steel alloy 1.4565 welds, thus affecting the resulting material properties. Different techniques for assessment of total nitrogen content and interstitial nitrogen content in stainless steel alloy 1.4565 are discussed and the results from each technique are compared.
