Abstract

The mechanical properties of a large group of commercial heats of three grades of pipe steel (17G1S-U, 10G2FB, and 12G2SB) are studied after controlled rolling. The interrelation of alloying, structure, and mechanical properties of the steels subjected to controlled rolling under the conditions of the Magnitogorsk Iron and Steel Works is studied, and the main structural factors responsible for strengthening of low-alloy steels are determined.
