Resistance of products made of steel 20GL to sulfide stress corrosion cracking

Abstract

The paper provides a short review of the history of the development of native and foreign regulatory requirements of testing for sulfide stress corrosion cracking. Systematic ambiguity (duplicated in the reviewed regulatory requirements) in the choice of test environment parameters and its influence on the interpretation of the results was revealed. A series of laboratory tests, the purpose of which was to specify the choice of the most favorable combinations of parameters (pH2S/pH combinations) of the test medium was conducted.
