Abstract

Status quo has been described on the national project for global standardization to define usable aluminum alloys for the use related hydrogen, focusing on the testing method. In the project, test of stress corrosion cracking under humid gas (HG-SCC, Humid Gas Stress Corrosion Cracking) has been proposed as the most suitable testing method. In 6000-series alloys with excess Si, those with and without Cu have been found to have and not to have resistance to HG-SCC, respectively. Since the knowledge on the stress corrosion cracking in 6000-series alloys is lacking compared to 7000-series alloys, further fundamental study is needed.
