Steel Processing: Differences Between Steel and Iron and the Seven Major Products of Steel Mills

#Steel Processing #CNC Processing #Automation Equipment Components #Aerospace Parts

Steel processing refers to the process of transforming metals like steel and iron through various techniques to create usable materials or finished products. This includes many advanced technologies and automation equipment, especially in the fields of CNC processing and steel processing. Below is a detailed explanation:

What is Steel? What is Iron?

1. Iron
   • A chemical element, symbol Fe.
   • Iron is found in nature mainly in the form of iron ore, which needs to be extracted by high-temperature smelting.
   • Characteristics:
     • Pure iron is soft and easily corroded.
     • Commonly used to produce steel or cast iron.
   • Types:
     • Pig Iron (carbon content 2.0%–4.5%): Brittle and hard, often used in castings.
     • Wrought Iron (low carbon iron, carbon content <0.05%): High purity but lower strength.
2. Steel
   • Steel is an alloy with iron as the main component, combined with carbon (carbon content 0.02%–2.0%) and other elements such as manganese, chromium, nickel, etc.
   • Compared to iron, steel has higher strength, ductility, and corrosion resistance.
   • Types:
     • Low Carbon Steel (high ductility, easy to process)
     • Medium Carbon Steel (balanced strength and ductility)
     • High Carbon Steel (high hardness, used for tools)
