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.
Standards: ASTM A36 (structural), EN 10025 (structural grades), SAE J403 (chemical composition). To find the actual document, try searching university

Selecting the wrong specification leads to catastrophic failure. Metallurgists study three primary failure modes: Steel is an alloy of iron (Fe) and
Understanding steel requires understanding its internal structure. Steel is an alloy primarily composed of Iron (Fe) and Carbon (C). The properties of steel are dictated by its microstructure and the way it is heat-treated.
| Treatment | Process | Microstructure | Effect | |-----------|---------|----------------|--------| | Annealing | Slow cool from austenite | Coarse pearlite | Softens, improves machinability | | Normalizing | Air cool from austenite | Fine pearlite | Refines grain, uniform properties | | Quenching | Rapid cool (water/oil) | Martensite (BCT) | High hardness, brittle | | Tempering | Reheat quenched steel | Tempered martensite | Reduces brittleness, increases toughness | ductility) and specifications (ASTM
From the bloomery furnaces of antiquity to the continuous casting machines of today, steel metallurgy remains a dynamic science. The relationship between properties (hardness, toughness, ductility) and specifications (ASTM, EN, SAE) is governed entirely by the material's metallurgical history—its alloying, heat treatment, and microstructure.
For the practicing engineer, carrying a steel metallurgy properties specifications and applications PDF is as critical as a calculator. It ensures that the steel under load will not just perform, but survive.
