Mild Steel

Composition: Iron alloy with 0.3% carbon. It is the most common form of steel and is relatively inexpensive and its properties of good ductility and poor brittleness lend it to many applications. It is the most frequently  used alloy in school projects.  It is ideal for structural work.

Properties: Malleable and ductile, and therefore bends fairly easily
Uses:  screws, tubes, girders , car body panels and many more everyday objects.

Appearance: Bright drawn mild steel has a smooth, bright surface; black mild steel is covered with a blue-grey oxide. Mild steel is prone to rusting and needs protection.
