What is the answer of max Carbon content allowed in mild steel, to be used in sheet metal for construction?

No @Yadnesh.

The low wrought iron range varies 0.1 to 0.25%. Thank you.

Yes, @Abrar.

It is 0.15%.

Wrought iron is an iron alloy with a very low carbon (less than 0.08%) content in contrast to cast iron (2.1% to 4%).

It is a semi-fused mass of iron with fibrous slag inclusions (up to 2% by weight), which gives it a "grain" resembling wood that is visible when it is etched or bent to the point of failure. Wrought iron is tough, malleable, ductile, corrosion-resistant and easily welded. Before the development of effective methods of steelmaking and the availability of large quantities of steel, wrought iron was the most common form of malleable iron. It was given the name wrought because it was hammered, rolled or otherwise worked while hot enough to expel molten slag. The modern functional equivalent of wrought iron is mild or low carbon steel. Neither wrought iron nor mild steel contains enough carbon to be hardenable by heating and quenching

In Construction industries, mild steel is used.

Wrought iron is the purest form of iron and contain carbon in less amount about 0.15%. According to R K Rajput Engineering materials.

MATERIAL ------- CARBON CONTENT IN %.
WROUGHT IRON ------- 0.02 to 0.03.
MILD STEEL ------- 0.1 to 0.3.
CAST IRON ------- 2 to 3.
PIG IRON ------- 3 to 4.

In desin of steel structures book - N.Subramanian.

The range of carbon up to 0.20%.
CAST IRON - 2.5-4.5 %.
STEEL - 0.1 - 1.1% OF CARBON But Here the Answer is 0.25%.

HOW?

In construction industries which iron widely use?

Wrought iron is an iron type which is pure and have a low carbon content up to 0.25%.
