Types of Carbon Steel
- Low Carbon Steel (Mild Steel): Highly ductile, formable, and easy to weld, ideal for a wide range of everyday items.
- Medium Carbon Steel: Good balance of strength and ductility, often heat-treated for enhanced mechanical properties.
- High Carbon Steel: Very strong and hard but less ductile, suitable for high-wear applications.
- Ultra-High Carbon Steel: Highest carbon content, extremely hard but brittle.
Carbon Steel Chemical Composition
Carbon steel primarily consists of iron and carbon, with carbon typically ranging from 0.05% to 2.00%, which determines its strength, hardness, and ductility. It also contains manganese, silicon, sulfur, and phosphorus in controlled amounts to improve strength, machinability, and overall performance. The exact chemical composition varies by grade and standard, with limits specified according to ASTM, ASME, EN, or other applicable material specifications.
Low Carbon Steel Chemical Composition
Low carbon steel is easy to shape and weld, making it a common choice for general construction.
