Pig Iron

Pig iron is the essential intermediate product formed during the smelting of iron ore in a blast furnace. Known for its high carbon content and high compressive strength, pig iron serves as a crucial raw material for steelmaking, foundry castings, and advanced alloy production worldwide.

Iron (Fe): ~92.0% – 94.0%

Carbon (C): 3.5% - 4.5%

Silicon (Si): 0.5% - 3.5%

Manganese (Mn): 0.3% - 1.0%

Phosporus (P): ≤ 0.12%

Sulfur (S): ≤ 0.05%

Length: 19 cm to 21 cm

Width: 13 cm to 15 cm

Height: 4.50 cm to 6.50 cm

Weight: 6 kg to 8 kg

• High Compressive Strength: Resists heavy compression forces effectively.
• High Brittleness & Low Ductility: Due to its 3.5–4.5% carbon content, pig iron cannot be bent, forged, or welded directly in its raw state.
• ​Low Melting Point: Pig iron melts at approximately 1,150°C to 1,200°C (significantly lower than pure iron at 1,538°C), making it energy-efficient to remelt in foundries and steel mills.
• Excellent Fluidity: Offers high fluidity when molten, making it well-suited for casting molds. 

• Steel Production: Refined into various grades of carbon steel, alloy steel, and stainless steel by removing excess carbon and impurities.
• Foundry Castings: Remelted with scrap to manufacture cast iron components such as engine blocks, machinery frames, manhole covers, and pipes.
• Wrought Iron & Alloys: Processed through decarburization to produce ductile wrought iron or specialized ferro-alloys.
• Powder Metallurgy & 3D Printing: Fine pig iron powder is used for additive manufacturing, sintered metal components, and automotive brake parts.
