Mild steel is an iron and carbon-based ferrous metal. It is a low-cost material with properties that are appropriate for a wide range of engineering applications. Because of its high iron content, low carbon mild steel has good magnetic properties and is thus classified as ferromagnetic.
Mild steel has a carbon content of 0.16 percent to 0.29 percent maximum and a melting point of 1450°C to 1520°C, which is relatively high. Steels with a higher carbon content have a lower melting temperature than mild steel. Because of its high melting temperature, mild steel becomes more ductile when heated, making it ideal for forging, cutting, drilling, welding, and fabrication.
Through hardening is not possible with mild steel. It can be case hardened by heating it and adding a chemically reactive carbon source, then quenching it to harden the surface layer. This outer layer, dubbed “the case,” will harden.
Galvanized steel, including mild steel, is recyclable.
In its untreated form, mild steel has a low corrosion resistance; however, by applying an appropriate surface protection product to the exposed parts of any project, the corrosion resistance can be greatly improved. To improve the appearance of mild steel and protect it from rust and corrosion, a variety of red oxide primers, metal paint, metal spray paint, and zinc treatments are available.
Pickling can be used to clean mild steel. Stains, contaminants, rust, and scale are all removed with this chemical surface treatment. Surface rust can also be removed using mechanical grinding and a surface protector like red oxide primer, zinc primer, or metal paints and sprays.
Mild steel is graded based on its chemical composition, manufacturing process, and properties, making it simple to select the best product for your project.
