What Is Mild Steel Sheet?

Steel is mostly composed of iron. Depending on different amounts of carbon content, there are low-carbon steel (also called mild steel or plain carbon steel), medium-carbon steel, and higher carbon steel.

The following chart shows the differences and characteristics of the three steel types

 

Carbon content (wt. %)

Characteristics

Examples

Low-carbon steel (Mild steel)

Less than 0.25

Pearlite, ferrite

Soft, cheap, very ductile, easy to machine and weld

AISI105, AISI 316L, Q195, Q215, Q235, 08F, 15Mn, 20Mn

Medium-carbon steel

0.25 to 0.60

Martensite

Reasonably ductile, hard, strong and not easy to harden

AISI 409, 45#, 40CR, 20CR, SCM 435

High-carbon steel (carbon tool steel)

0.60 to 1.25

Pearlite

Very hard, strong, unyielding, hard to machine and weld

T7, T7A, T8Mn, T8MnA, AISI440C

 

From the above chart, mild steel is a steel type that contains 0.05%-0.25% carbon. Due to its malleability and ductility, the material is easy to form and machine. Mild steel parts are generally very suitable for stamping, forging. Mild steel is widely used in tools, automotive body parts, construction, and infrastructure.

Mechanical Properties Of Mild Steel

As you could judge from the chart above, mild steel has lower carbon content than other carbon steel. The mild steel has a mere carbon content of 0.25%.

Mild steel has great impact strength, great ductility and weldability, good malleability with cold-forming possibilities. With these properties, CNC-machining mild steel is easier than CNC-machining other types of steel.

The major disadvantage of mild steel is that it has a relatively low tensile strength, which means it’ll break more easily than other types of steel.

Fortunately, a heat-treatment process called carburizing can be used to improve tensile strength. Carburizing is a surface-hardening process that heats the mild steel to a certain temperature then cools down the steel, which makes the steel hardened on the surface when keeping the core of the steel soft and ductile.
