Differentiate between cast iron , wrought iron and steel .
Answers
Answer:
Cast iron is iron that has been melted, poured into a mould, and allowed to cool. Typically cast iron contains 2-4% carbon, it is non-malleable, hard and brittle.
Wrought iron is iron that has been heated before being worked with tools to shape it. Wrought iron has a very low carbon content (less than 0.08%), and is characteristically fibrous in appearance, but compared to cast iron it is softer and more ductile. Wrought iron resists fatigue and has a higher tensile strength than cast iron.
Steel is an alloy of iron with typically a few percent of carbon to improve its strength and fracture resistance compared to iron. It is the interaction of the allotropes of iron with the alloying elements, primarily carbon, that gives steel and cast iron their range of unique properties.
