- Ni at least 0.50% to at most 3.75% and V: at least 0.15% to at most 0.45%.
- the advantage of the steel alloy which is slow to transform according to the first aspect of the invention is, in particular, that it can be cooled or quenched in air and nevertheless achieves good strengths and high hardnesses.
- the inert steel alloy according to the first aspect of the invention enables a heat treatment without a special medium, such as for example oil or water, for quenching.
- Quenching in air compared to quenching with other media is particularly advantageous for large components.
- the inert steel alloy is accordingly outstandingly suitable for a component of a hydrogen storage device which is designed to contain or flow through hydrogen.
- a component can, for example, be a tank for holding or storing hydrogen, so be a hydrogen tank.
- Such a component can also be, for example, a pipe through which hydrogen flows through or transports it. Accordingly, such components are usually relatively large in size. If such components are not quenched in air but with other media in order to achieve the desired good strength and high hardness, the production is correspondingly complex and cost-intensive.
- the inert steel alloy according to the first aspect of the invention is not limited to components of a hydrogen storage unit designed to contain or flow through hydrogen, but can also be used for other purposes and components. However, it has been shown that it is particularly well suited for use in a hydrogen atmosphere.
