Carbon steel is steel that contains between 0.12% and 2.0% carbon and is the main interstitial alloying constituent. Carbon is used in steel-making as a hardening agent whereby the greater the level of carbon, the harder and stronger the steel is through heat treating (however, the more carbon, the less ductile the steel will be). In carbon steels, the higher the carbon levels, the lower the melting point. Mild steel contains only a small percentage of carbon.

Mild steel contains only a small amount of carbon but is still is strong and tough with quite a high melting point. It is also known as plain-carbon steel.

Mild steel is the most common form of steel due to its low price and versatility across several applications. Low-carbon steel contains approximately 0.05–0.25% carbon making it malleable and ductile.

Structural Steel

Mild steel is often used when large quantities of steel are needed. Structural steel is a common application.

Here are some common examples of mild steel used for structural purposes:

Parallel Flange Channels

Parallel channelled beams are U-shaped with right-angled corners. They come in different sizes; however, the two sides are always the same length and are parallel. They also offer a high strength to weight ratio and have similar uses to angled sections.

Tapered Flange Beams

Taper flange beams are I-shaped sections and are also available in a wide variety of sizes. In construction, these are often used for cross-sections of girders. Though they have quite high resistance ratios, they are not usually recommended when pressure is present along their length as they are not torsion (twisting) resistant.

Universal Beam

Universal beams, also known ad I-beams or H-beams, are shaped like their namesake: an ‘I’ when standing upright and a ‘H’ on their side. Universal beams are usually made of structural steel and are used in construction and civil engineering, among other industries.

Universal Column

Universal beams are also widely used for structural purposes. They are similar to beams and are often called I-beams or H-beams; however, all three sections are equal in length. As their name suggests, they are mainly used for columns and have fantastic load-bearing capabilities.

These are just a few of the most common types of structural steel. Read more about it here.
