      cast iron is basically steel, but has it’s own name because it’s brittle. roughly between half a percent to 3 percent carbon (among other things) is the base of many steels. “cast iron” is about 4 percent carbon and pretty much no ductility

          What do you think carbon steel is made from?

          Cast iron and steel are largely similar materials, cast iron just has the carbon precipitated out of solution instead of trapped in a crystalline structure
