Steel: The most common iron alloy, containing varying amounts of carbon, alloying elements (e.g., chromium, nickel, manganese), and other elements to improve its properties.
Cast Iron: An iron alloy with a higher carbon content than steel, making it more brittle but easier to cast.
Wrought Iron: A low-carbon iron alloy with a fibrous structure, making it malleable and ductile.
Chemical Composition: The percentage of iron, carbon, and other alloying elements.
Physical Properties: These include hardness, tensile strength, ductility, malleability, and melting point.
Mechanical Properties: These include yield strength, ultimate tensile strength, elongation, and reduction of area.
Dimensional Tolerances: The allowable variations in size and shape.
Surface Finish: The quality of the surface, including roughness, smoothness, and appearance.
Standards: Adherence to industry standards, such as ASTM, ISO, or SAE.
