This paper focuses on the microstructural characteristics of non-alloy structural steels with carbon contents below 0.3% (further—Low-Carbon Steel—LCS), as well possible transformations and resultant mechanical properties attainable through conventional heat treatment or alternative surface methods. The principal constituents that govern these include both equilibrium non-equilibrium phases, such martensite, retained austenite, sorbite, troostite. Conventional methodologies for enhancing rigidity involve implementation supplementary stiffening ribs, which augment while concomitantly contributing to an increase in overall weight dimensions structure. In structures where ribs are incorporated within thin-walled steel shell, this may reduce manufacturing efficiency simplicity design. Modern laser technologies structures, however, modifying internal microstructure creating structure itself, thus circumventing need additional elements.
