A New Approach to the Optimization of the Austenite Stability of Metastable Austenitic Stainless Steels

Journal of Materials Engineering and Performance, 2023
AbstractAustenitic steels used for components in high-pressure hydrogen storage systems in the automotive sector have to meet high requirements in terms of material properties and cost efficiency. The commonly used 1.4435/AISI 316L type steels fulfil the technological requirements but are comparatively expensive and resource-intensive.
