Steel Metallurgy: Properties, Specifications, and Applications

1. Fundamentals of Steel Metallurgy

Steel is an alloy of iron (Fe) and carbon (C) , typically containing 0.02% to 2.1% carbon by weight. Other alloying elements are added to modify mechanical and physical properties.

• Annealing: Heating and slow cooling to soften steel for machining.
• Quenching: Rapid cooling (often in oil or water) to harden the steel.
• Tempering: Re-heating quenched steel to reduce brittleness while retaining hardness.
• Normalizing: Refining the grain structure to ensure uniformity.

Ductility & Elongation: The capacity of the steel to deform under tension without fracturing, essential for forming and safety in construction.
