The development of high interstitial stainless austenitic steels (HIS) is aimed at a production without costly pressure or powder metallurgy as required by some high nitrogen steels (HNS). At a C + N content between 0.8 and 1.1 mass % the strength level is to be raised considerably above that of standard low interstitial grades. To this avail a multiscale investigation covers the electron structure, microstructure, constitution, properties and manufacturing of new HIS.
