Basic concepts of what steel is and its production.
Steel is a metallurgical product made basically from the fusion of Iron plus Carbon, being adopted as definition of Steel to Iron Alloy with a percentage of Carbon between 0.008% and 2.11%.
Alloys of Carbon above 2.11% are called Cast Iron.
The main difference between Steel and Cast Iron is that Steel, due to its ductility, is deformable by forging, lamination, drawing, extrusion and stamping, whereas Cast Iron, as it is a more fragile product, cannot be subjected to these processes and is cast in molds which can be machined into the final product.
Iron is the chemical element in the composition of steel that is obtained from ores (rocks) that are extracted from mines in nature.
The main iron ore are:
Magnetite = 72% Iron content
Hematite = 70% Iron content
Limonite = 63% Iron content
Siderite = 48% Iron content.
