Description
Summary:Results from a study of the structure and properties of the metal of drums made of Grade 16GNM steel that have been in operation for a long period of time are presented. A change in the strength characteristics and fracture ductility of metal with respect to its initial properties indicated in its certification data is analyzed. It is shown that changes in the strength properties of the metal of drums do not demonstrate any stable trends with an increase in the time of its operation.
