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.

C.I and Pig iron - 2 to 5%.
Steel - 0.5 to 1.5%.
W.I - 0.1 to 1.25%.
Mild steel - less than 0.25.

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.

High carbon steel =0.8 -1.5.
Medium (high tensile)=0.3-0.8.
Mild =0.15-0.3.
Dead mild= less 0.15.

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.

Vishal pandya said:   6 years ago
Yes, @Abrar.

It is 0.15%.
