Carbon Steels


Engineering Studies – P3 Braking Systems – Materials and Manufacturing

This topic investigates the definition, structure and applications of carbon steel. The effect that steel phases have on the properties are outlined.

Key Concepts

  • Carbon steel definition
  • Carbon steel structure
  • Carbon steel applications

Discussion Questions

  1. What is the normal range of carbon in plain carbon steels?
  2. As the carbon content increases from 0 to 4.3%, how does steels;
    • tensile strength change?
    • ductility change?
  3. What range of carbon steels are heat treatable?
  4. Describe these steel phases:
    • Pearlite
    • Ferrite
    • Cementite
