A comparative study is provided for the effect of different alloying versions on phase transformation, structure, and mechanical properties of low-alloy pipe steel. Steel alloyed economically with chromium is developed for producing sheet 21.6 (21.7) and 25.8 mm thick of strength class K60 intended for manufacturing pipe up to 1420 mm in diameter for main pipelines with a working pressure of up to 9.8 MPa.
