The goal of the HYSTORY project is to develop Mn austenitic stainless and non stainless steels via high throughput metallurgy screening.

The project targets the development of innovative grades for hydrogen production (PEM electrolysers), cryo-compressed hydrogen storage and compressed hydrogen transport.

Therefore, the susceptibility to hydrogen embrittlement and the interaction between hydrogen and the microstructures will be deeply studied.

The positioning of the novel developed grades versus current steel solutions (austenitic stainless 316L and ferritic line pipe grade) will be assessed in terms of hydrogen embrittlement susceptibility and steel manufacturing competitiveness.

In addition, key performance indicators defined for each studied property and weight algorithm will assist the optimization of the metallurgies and the alloys comparison.
