摘要
In this paper questions related to damage of the power equipment from austenitic stainless steel are considered. It is established, that occurrence of cracks type intercrystalline corrosion fracture in the austenitic stainless steel welded joint heat-affected zone caused by 3 factors - the certain degree of base metal sensitization, high operating voltage level and increased (in comparison with the normative documentation at operation) oxygen concentration in the heat-carrying agent.
