Many researches are done for finding various ways of improving steel properties, since it's the most used material in the world. Instead of using high-alloyed steels, which are expensive, microalloying of carbon steels that will retain equal properties is an efficient replacement. For this research it was tested melts of low-carbon steel grade SAE 1006 produced via basic oxygen furnace in company ArcelorMittal Zenica. Secondary treatment was done via ladle furnace, where to liquid steel was added the microalloying element boron in the form of FeB wire. The results showed that the microstructure of all melts was ferritic with the content of pearlite in traces. Pearlite content was lower in the melts with boron. It also showed that boron addition caused growth of ferritic grain
