how is wrought iron different from steel???

Definitions

• While people sometimes use the terms “wrought iron” and “steel” interchangeable, wrought iron combines pure iron ore with a glassy material called iron silicate, while steel also contains carbon, according to Chemguide.co.uk.

Production

• Both metals go through a firing process to give them strength. Wrought iron forms during charcoal firing or as a byproduct of cast iron production, according to the Real Wrought Iron Company. Steel forging adds and removes various compounds and oxides to create the final alloy.

Strength

• Steel possesses greater tensile strength than wrought iron. Steel may show more vulnerability to corrosion than wrought iron, with the exception of stainless steel.

Telltale Differences

• Wrought iron and mild steel may bear a close resemblance at first glance, but close inspection by an expert often reveals rougher workmanship and more corrosion in the steel product.

Considerations

• Cheaper, more lightweight materials such as aluminum and other alloys have largely replaced true wrought iron in many home applications, despite the greater durability of wrought iron.
