BBN steel formulates appropriate S45C carbon structural steel product internal control components, strictly controls the fluctuation range of chemical components, and ensures the stability of steel plate performance. Strengthen batching control and smelting operations, effectively control the content of harmful elements such as Sn, Sb, As, Cu, and reduce the content of P and S to improve the purity of steel, reduce the tendency of temper embrittlement, and improve the high temperature corrosion resistance of steel. It adopts controlled heating to ensure heating time and temperature, and measures such as controlled rolling to ensure the inherent quality of the steel plate.
S45C carbon structural steel product plate specification range: Thickness 3-150mm Width 1500-4020mm Length 4000mm-17000mm Heat treatment: annealing, or normalizing and tempering
Oxygen is a harmful element in S45C carbon structural steel steel. With the increase of oxygen content, the strength of S45C carbon structural steel steel increased, but the plasticity, especially the toughness, decreased significantly, and the weldability became worse. The presence of oxygen causes hot brittleness of S45C carbon structural steel steel.
