Ripple-load test in hydrogen environment

Metallic materials exposed to hydrogen can exhibit degradation of their mechanical properties during their service life due to hydrogen embrittlement. Ripple-load test (RLT) together with slow strain rate testing (SSRT) and constant load testing are mechanical tests meant to assess the materials resistance to cracking in different environments.


Assessing metallic materials suitability to hydrogen service can be a difficult task as the effects of hydrogen can take long time to be visible. We offer different testing methods to assess the suitability and compatibility of materials exposed to hydrogen, which can support an adequate materials selection.


Ripple-load test (sometimes referred to as rippled strain rate testing, RSRT) is a modified slow strain rate testing to assess hydrogen assisted cracking by applying tensile load cycles. We offer RLT under high pressure hydrogen gas (up to 120 bar) as a solution to assess susceptibility of metallic materials to hydrogen assisted cracking.
