What is steel, anyway? Wikipedia tells us that steel is an iron-based alloy with a carbon content of between 0.02% and 2% by mass, which may or may not contain other chemical elements (impurities). The elements added to iron modify its physico-chemical characteristics. Carbon is always present, but in variable quantities, which influences the alloy’s maximum hardness or its ability to be enamelled, for example. When the carbon content exceeds 2....
