Abstract
Presented are generalized results of investigation of fasteners metal (steel EP-182) that have exhausted their fleet resource (more than 220000 h) in 300-MW steam turbines, and analysis of impact of operation time, structure, and service conditions on mechanical properties of the metal. Comparison of the results obtained with the permitted values is conducted. Conclusions regarding the possibility and conditions of the further use of fasteners after exhaustion of their fleet resource are given.
