Understanding the fracture behavior of metallic materials in high-pressure H2 environments can be useful for selection of materials in underground H2 storage. Currently, there are sparse data on fracture mechanics of metallic materials typically used in oil and gas well construction when subject to high-pressure H2 gas environments.
The test program detailed in this technical report is an effort to generate data to provide some insight into testing procedures and material behavior, which over time could help the industry in evaluation and selection of materials in such service.
