Equivalent carbon content - Wikipedia
In welding, equivalent carbon content (C.E) is used to understand how the different alloying elements affect hardness of the steel being welded. This is then directly related to hydrogen-induced cold cracking, which is the most common weld defect for steel, thus it is most commonly used to determine weldability.
After rolling process, the plate is treated by water cooling device, Super-OLAC(Online Accelerated Cooling), and gains finer grain in microstructure than the conventional steel. Having the finer grain micro-structure, TMCP steel plate achieves higher strength and toughness than the conventional steel. Especially, the higher yield
