Important results from the project
HYSTRENGTH aimed to investigate why nitrogen-alloyed austenitic stainless steels such as 1.4420 are not used more widely. These steels are particularly well suited for hydrogen applications and have higher strength than 1.4404, which is commonly used. Case studies carried out within the project show that material savings of more than 36% can be made if 1.4420 is used instead of 1.4404. Several filler materials have been welded and tested and plans for specific hydrogen testing have been made.
Expected long term effects
The project has laid the foundation for continued work to increase the pace of implementation of higher-strength materials for safe hydrogen storage and transport. With a better understanding among materials and additive manufacturers of how these materials are best used and where the challenges lie, implementation can increase with more sustainable designs of hydrogen devices, tanks and pipelines as results.
Approach and implementation
The project ran from November to August. The experimental work was somewhat delayed and much of the testing was done in the final stages of the project. It has not been optimal for the project as a whole that the results are coming in late. In terms of activities, the project has been wisely planned and has been able to carry out the activities that were planned. The cooperation between the parties has worked well and is already well established in other projects.
