Conclusions
Microalloying of Cr−Ni−Mn steel with boron in amounts of 0.002–0.005% (nominal) increased the ductility at 900–1100° by 100–125%, making it insusceptible to hot shortness. This improves the deformability of the ingots and slabs. With an increase of the boron concentration from 0.005 to 0.10% the ductility of the steel is greatly impaired at temperatures above 1100°.
In view of the susceptibility of the steel to overheating at temperatures above 1260°, the optimal temperature for heating the ingots is 1240–1260° on condition that they be held in the range of 1200–1220° in the first stage of heating.
