Copper, as a significant residual impurity in steel, can cause severe microstructural distortions if not managed within specific limits. This study examines how varying concentrations of copper influence the mechanical properties of construction steel, ultimately aiming to establish safe thresholds for its presence. Methodologically, the research involved the collection of statistically scheduled samples of hot rolled profiles exhibiting copper concentrations ranging from 0.12 wt. % to 0.39 wt. %. Standard test specimens prepared from these samples underwent a suite of tests including tensile, impact, and hardness assessments, alongside microstructural analyses. The findings reveal substantial deterioration in mechanical performance; specifically, as copper levels escalate from 0.12 wt. % to 0.39 wt. %, tensile strength, impact energy, and hardness diminish by 54.3%, 74.2%, and 64.9%, respectively. Such a drastic decline in performance is attributed to significant microstructural distortions resulting from the formation of incoherent complex compounds, which compromise the integrity of the pearlite reinforcing phase. The study concludes that copper concentrations exceeding 0.22 wt. % are detrimental to the efficacy of construction steel.
