Carbon Steel vs. Cast Iron Pans: What's the Difference?

Apr 08, 2020· Whereas steel requires a carbon content of no more than 2 percent, cast iron usually contains 2 to 3.5 percent carbon. It's the carbon content that gives cast iron its rough, slightly bumpy feel. Its higher carbon content makes cast iron more brittle than steel (which is why it needs to be so heavy and thick—if it were thinner, it would break).

Oct 12, 2016· Cast iron: Used for more than 1,000 years in construction, tool-making, and ornamentation, cast iron is pure iron alloyed with more than two percent carbon (which, ironically, means cast iron contains more carbon than carbon steel).Cast iron isn’t malleable, so it can’t be hammered into shape. It’s also a fairly brittle metal, making it susceptible to breakage.
