Increasing the efficiency of microalloying steel with boron‑containing alloys

Abstract

Compositions for microalloying steel with boron are presented, its positive effect on the process of steel crystallization, increasing strength and toughness is shown. The feasibility of using boron‑containing ferroalloys with low boron concentrations is substantiated. The need to use complex boron‑containing alloys to neutralize nitrogen and oxygen is noted. An example of a complex alloy based on ferrosilicon and ferromanganese with boron additives, obtained using datolite concentrate, is given.
