Well Said. Thanks all.

Very good, Thanks all for giving explanations.

Wrought iron is a form of commercial iron containing less than 0.10% of carbon. Less than 0.25% of impurities like Sulphur, Phosphorus, Silicon, and Manganese.

Wrought iron contains carbon up to 0.25% due to its production process, which involves repeatedly heating and hammering iron to remove impurities, including excess carbon.

This low carbon content gives wrought iron its characteristic malleability, toughness, and resistance to corrosion, making it ideal for forging and construction purposes.

What is the use of carbon for iron? Please explain.

Wrought iron is an iron alloy with a very low carbon content (less than 0.05%) in contrast to that of cast iron (2.1% to 4.5%).

It is a semi-fused mass of iron with fibrous slag inclusions (up to 2% by weight), which gives it a wood-like "grain" that is visible when it is etched, rusted, or bent to failure. Wrought iron is tough, malleable, ductile, corrosion-resistant, and easily forge-welded, but is more difficult to weld electrically.

Wrought iron contains carbon up to 0.25%.

It is known for its low carbon content, which makes it malleable, ductile, and resistant to corrosion, but not as strong as steel.
