Technical Report: Iron-Based Alloys (Ferrous Alloys) Iron-based alloys, commonly referred to as , are the most widely used metallic materials in the world due to their abundance, low cost, and highly versatile mechanical properties. These alloys are primarily categorized based on their carbon content and the addition of specific alloying elements like chromium, nickel, and silicon. 1. Classification of Iron Alloys
: Focus on cost-effective strength and weldability. alloy iron
: Processed to form graphite spheres, providing better ductility than gray iron. 2. Key Alloying Elements and Their Effects commonly referred to as
: An alloy of iron and carbon (typically <2.1% carbon) that offers high tensile strength and ductility. alloy iron
: Iron-carbon-silicon alloys with carbon content typically between 2.5% and 4.0% . Their high fluidity when molten makes them ideal for complex casting shapes.
