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.

Materials and Corrosion, EarlyView.The hardness and corrosion resistance of the martensitic stainless steel X30Cr13 depend directly on the applied heat treatment. This article describes and discusses the relationships between alloy composition, thermodynamic phase stabilities, heat treatment parameters, resulting microstructures, and achievable corrosion resistance. To investigate these

steel research international, EarlyView.The phase transformation behavior of a hypoeutectoid steel is studied in comparison with alloys containing higher concentrations of tramp elements, simulating high recycling rates. The examination of microstructures reveals that the tramp elements facilitate the formation of displacive phases along with retained austenite.
