What is steel ,what is cast iron,difference between steel and cast iron

Question

Accepted Answer

Steel and cast iron are both alloys of iron, but with different carbon content and properties.

Steel is an alloy of iron and carbon, with a carbon content of less than 2%. It is stronger, more ductile, and more malleable than cast iron.
Cast iron is an alloy of iron, carbon, and silicon, with a carbon content of 2-4%. It is more brittle and less malleable than steel.
Steel is used in construction, machinery, and tools, while cast iron is used in pipes, engine blocks, and cookware.
The difference in properties is due to the difference in carbon content and the way the alloys are made.
Steel can be further classified into different types based on the amount of carbon and other elements added, such as stainless steel, tool steel, and carbon steel.
