Due to the small amount of alloying elements (compared to typical medium-Mn steels containing 6-12 wt.% Mn) it will be possible to reduce the production costs. Manganese is a cheap alloying element that increases the strength and hardenability of steel (it replaces the expensive chromium typically used to improve the hardenability of steel). The Nb microaddition allows to obtain an ultra-fine-grained microstructure that allows obtaining high strength steel while maintaining good plasticity and fracture resistance. Low carbon content will improve the weldability of steels. Partial replacement of silicon with aluminum will have a positive effect on increasing the susceptibility of steels to galvanization.
