What is Fe 415 in steel?

Fe 415 is a designation for a type of mild steel used in construction and engineering, where "Fe" stands for iron and "415" indicates the minimum yield strength of the steel in megapascals (MPa). This grade of steel is commonly used in reinforced concrete structures due to its good ductility and strength. Fe 415 typically contains a carbon content of up to 0.25%, which contributes to its mechanical properties. It is often utilized in various structural applications, including beams, columns, and slabs.
