The mechanical properties, the microstructure, and the cold resistance of coiled strips from low-carbon manganese-and silicon-alloyed steels with different additions of niobium and titanium produced by direct rolling of thin slabs right after their continuous casting under the conditions of foundry-rolling works are studied. It is shown that the addition of 0.01% Ti into the steel alloyed with 0.04% niobium has a positive effect on the ductility, toughness and cold resistance of the rolled strips and a negative effect on the strength. A high (0.08%) content of niobium is favorable for the impact toughness and resistance to brittle fracture of Charpy specimens of the steels studied under negative temperatures of up to –80°C.
