As published by Metalbook in “Mild Steel vs Hot Rolled Steel: Key Differences,” Pragati Tiwari explains how selection comes down to how the steel is made and what your project needs in strength, finish, price, and ease of fabrication.

Hot rolled steel is made by heating steel slabs to very high temperatures (often over 1700°F / 927°C) and rolling to size, then cooling naturally, which leaves mill scale and a rougher surface. Mild steel is defined by low carbon content (commonly around 0.05% to 0.25%), which supports ductility, weldability, and machinability, but also means it needs protective coating in wet environments to reduce rust risk. The comparison also covers tradeoffs: hot rolled is often chosen for large structural work where forming ease and cost matter, while mild steel (especially when cold rolled) fits projects needing tighter tolerances and a smoother finish.
