Cast and especially pig iron have excess slag which must be at least partially removed to produce quality wrought iron. ... Another difference is that steel can be hardened by heat treating.

Why is cast iron not weldable?

Cast iron is difficult, but not impossible, to weld. ... Cast iron typically has a carbon content of 2% - 4%, roughly 10 times as much as most steels. The high carbon content causes the carbon to form flakes of graphite. This graphite gives gray cast iron its characteristic appearance when fractured.

Is Cast Iron breakable?

The myth here revolves around the misconception that cast iron breaks easily and is difficult to maintain because there are a lot of “rules.” It can rust to the point of being unsalvageable, chip or even crack or break easily, so it's basically the kitchen equivalent of a Fabergé egg.
