摘要：

We estimate the characteristics of strength, ductility, and static crack resistance of 12Kh1MF steel taken from the stretched, compressed, and neutral zones of a vertical bend and a straight part of the main steam pipeline of a thermal power plant after similar to 1.3 a <...10(5) h of operation. The anisotropy of the mechanical char acteristics in the diametric and axial sections of the pipe and their gradients across the thickness of the pipe wall in fracture are discovered.
