Abstract: A component of an electrochemical device includes a substrate made of stainless steel, where the substrate is further characterized by a microstructure containing an intermetallic compound. A component of an electrochemical device includes a substrate having at least one surface, where the substrate is made of stainless steel. The component further includes at least one surface coating layer on each of the at least one surface. Each of the at least one surface coating layer includes a carbide material or a MAX phase material.

Abstract: A component (3; 3?) for an injection system (1), in particular a high-pressure line (5) or a fluid distributor (2), including a base body (14; 13), at which a high-pressure input (15; 12) and at least one high-pressure output (16 through 19; 12?) are provided, at least the base body (14; 13) being at least essentially formed from an austenitic or martensitic material. It is provided that the material is developed as a grain-stabilized material.

Abstract: The invention relates to a slow-transforming steel alloy for a component of a hydrogen store, which component is designed to contain or to be flowed through by hydrogen, wherein the slow-transforming steel alloy has a Vickers hardness of at least 300 HV and the slow-transforming steel alloy contains C, Si, Mn, P, S, Cr, Mo, Ni and/or V as alloy elements, the mass fractions of the alloy elements equaling: —C: at least 0.125% to at most 0.525%, —Si: 0.0% to at most 0.375%, —Mn: 0.0% to at most 0.375%, —P: 0.0% to at most 0.0145%, —S: 0.0% to at most 0.225%, —Cr: 0.0% to at most 0.25%, —Mo: at least 0.81% to at most 4.05%, —Ni: at least 0.50% to at most 3.75% and —V: at least 0.15% to at most 0.45%. The invention furthermore relates to a method for producing the slow-transforming steel alloy and to a hydrogen store having the component consisting of the slow-transforming steel alloy.
