Steel metallurgy involves the study of iron-carbon alloys containing less than 2% carbon It is highly strained, exceptionally hard, and brittle

A "specification" is a legally binding document that dictates the chemical composition, mechanical properties, and manufacturing method. Using the right specification is critical for safety and compliance. Steel is specified based on its composition, microstructure,

Steel is specified based on its composition, microstructure, and properties. Some common specifications of steel include:

| Property | Definition | Typical Range (Structural Steel) | |----------|------------|----------------------------------| | Yield Strength (σ_y) | Stress at plastic deformation onset | 250–1000+ MPa | | Tensile Strength (σ_uts) | Maximum engineering stress | 400–1200+ MPa | | Elongation (%) | Ductility measure | 10–30% | | Hardness (HB) | Resistance to indentation | 120–600 HB | | Toughness (CVN) | Energy absorbed in impact | 20–200 J (at room temp) | | Fatigue Limit | Endurance under cyclic load | 0.3–0.5 × σ_uts |

Extremely hard and brittle, formed by rapid quenching. 2. Properties of Steel
