Steel industries are responsible for reducing CO2-emission in its process and providing high-performance steel products that reduce overall emissions. We will bring up innovative high-strength stainless steels for high-pressure gaseous hydrogen and liquid hydrogen, that will be used in new energy sectors. High-Strength Stainless Steels for High-Pressure Gaseous Hydrogen is crucial for the hydrogen economy. Advanced high-strength stainless steels resist hydrogen embrittlement better than conventional materials, supporting compact, efficient infrastructure development. High-Strength Ni Steels provide excellent cryogenic toughness for liquefied hydrogen storage and transport. These materials are preferable over austenitic stainless steel for certain conditions due to their lower thermal expansion and high strength. One of the challenges for the above high-strength steel products to be widely used in the hydrogen society is to overcome hydrogen embrittlement. This paper addresses Alloy Design for Reduced Susceptibility to Hydrogen Embrittlement emphasizing microstructure control, alloy design, and the electronic theory of hydrogen embrittlement. |
