- Applications: Construction, automotive bodies, general fabrication
- Properties: Excellent weldability, high ductility, easy forming
- Market Share: Largest segment due to widespread applications
Medium Carbon Steel:
- Carbon Content: 0.30-0.60%
- Applications: Machinery components, axles, gears
- Properties: Balanced strength and ductility
- Heat Treatment: Responsive to hardening processes
High Carbon Steel:
- Carbon Content: 0.60-2.00%
- Applications: Tools, springs, cutting instruments
- Properties: Maximum hardness and wear resistance
- Specialized Uses: Premium applications requiring durability
Alloy Steel Specifications
Alloy steels incorporate additional elements for enhanced properties:
- Chromium: Increased hardness and corrosion resistance
