    Abstract

    A test method for assessing hydrogen embrittlement of high-strength steel parts in the field is described. It is applicable to both ferrous and nonferrous metals which evolve hydrogen when heated. The assessment of the hydrogen embrittlement of steel or other metal parts is dependent on the determination of the local hydrogen content and the stresses required to fracture them and the determination of the hydrogen pick-up rate by the metal part in the environment which it is exposed to. Local hydrogen analysis in the field is based on the application of a flexible neodymium hydrogen detection tape.
