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.
You can use this guide as a study resource. If you still need a physical file, I have included a list of legitimate sources where you can download such PDFs at the end. Chemical composition : Steel is specified based on
Steel is categorized into four primary groups based on its chemical composition and intended use: Required mechanical properties (strength
- Chemical composition: Steel is specified based on its chemical composition, including the percentage of carbon, manganese, chromium, and other elements.
- Microstructure: Steel can have different microstructures, including ferrite, pearlite, bainite, and martensite.
- Mechanical properties: Steel is specified based on its mechanical properties, including tensile strength, yield strength, and elongation.
- Surface finish: Steel can have different surface finishes, including hot-rolled, cold-rolled, and coated.
- Required mechanical properties (strength, hardness, toughness)
- Corrosion environment (humidity, chemicals, salt)
- Fabrication methods (welding, machining, forming)
- Heat treatment (through-hardening, case-hardening)
- Cost & availability
- Specifications/certifications (ASTM, ISO, customer standards)
Types of Steel
Construction and Infrastructure: ASTM A36 and A992 structural steels are the foundation of skyscrapers, bridges, and tunnels due to their high yield strength and seismic resilience. toughness) Corrosion environment (humidity
