Principles are established for controlling low-alloy steel structure formation during thermomechanical treatment for the possibility of creating steels for different purposes from slabs of a single chemical composition. Technology is developed for manufacturing high-strength shipbuilding steels with a yield strength of 460 MPa and strength category K65 pipe steels of unified chemical composition.

Notes
* An algorithm uniting a connected multitude of points to a single structural element is realized in accordance with previously prescribed grouping indices, the main one of which is tolerance angle θ t . In implementing this grouping algorithm, two neighboring points were assumed to be adjacent to the same structural element (grain), if the misorientation between them did not exceed θ t .
