What is difference between cast iron , wrought iron, steel?
Answers
Answer:
Explanation:
Cast iron is a solid solution or alloy of iron (as in the element iron) and between two and 4% carbon. Silicon may also be added. It is used as a cast product going from the molten state in the ladle to the solid state in a mold shaped pretty much as the item will be used in the finished state. Cast iron is brittle and can’t be worked either hot or cold.
Wrought iron is a different solution or alloy of iron (as in the element iron) with less than .08% carbon. It is, in effect, a much more pure form of the metal iron. It is much more ductile and has a higher melting point than cast iron. It used to be forged or “wrought” from an ingot or casting into the article desired. Wrought iron is malleable and could be hot worked without breaking.
Wrought iron is not commercially available anymore and most things made of “wrought iron” are usually made of mild steel.
