Hydrogen embrittlement is a pervasive and dangerous issue for many types of materials, and it is especially (but not exclusively) affecting high strength steels. The determination of the susceptibility of materials to delayed fracture in the actual service environment is necessary to an appropriate materials selection.
Purpose
Some mechanical tests such as Incremental Step Load (ISL) / Rising Step Load (RSL) testing in the actual service atmosphere can support your materials selection. We offer step load testing in high pressure gaseous hydrogen atmosphere.
Method
During the step load testing, the specimen is loaded in incremental steps until failure, resulting in the evaluation of its toughness under the test conditions as an assessment of its sensitivity to hydrogen embrittlement. Tests are conducted on standard fracture mechanic specimens (compact tension, CT) pre-cracked in fatigue before testing.
In addition to testing in hydrogen gas, we offer step load testing of specimens that are either hydrogen charged in-situ during the testing or that are pre-charged.
