Know Wrought Iron

It is a famous saying that, just like all the things subjected to evolution, that which improves up on its predecessor almost inevitably replaces it. That is exactly the case with the emergence of steel as a clear improvement upon, if not a replacement for wrought iron.
The superiority of steel over wrought iron can be found in its strength and consistency, which gives it a much wider range of applications than wrought iron, including its ability to be hardened by a heat treatment. Many metalworkers are comfortable in using this much cheaper metal both for new work and the rehabilitation of the old.
