2. What is High Carbon Steel?
High carbon steel is a high-strength carbon steel alloy with significantly higher hardness compared to low and medium carbon steels. Its high carbon percentage (0.60–1.25%) makes it:
Extremely hard and wear-resistant
Capable of achieving very high strength after heat treatment
Less ductile and more brittle than lower carbon steels
It is widely used in knives, springs, cutting tools, wires, dies, and high-stress machine components.
3. Physical Properties of High Carbon Steel
| Property | Value |
|---|---|
| Density | 7.85 g/cm³ |
| Melting Point | ~1,370 – 1,480°C |
| Thermal Conductivity | ~50 W/m·K |
| Electrical Resistivity | 0.20 μΩ·m |
| Magnetic Properties | Ferromagnetic |
4. Mechanical Properties of High Carbon Steel
| Property | Range |
|---|---|
| Yield Strength | 600 – 1,200 MPa |
| Tensile Strength | 900 – 1,500 MPa |
| Elongation (A80) | 5 – 10% |
| Hardness (HB / HRC) | 250 – 65 HRC |
| Wear Resistance | Very High |
5. Advantages of High Carbon Steel
✅ Superior Hardness – Ideal for cutting tools, knives, and dies
✅ High Wear Resistance – Long lifespan in abrasive environments
✅ Strong Edge Retention – Perfect for blades and springs
✅ Excellent Load Resistance – Withstands high-stress conditions
✅ Cost-Effective – Cheaper than alloy steels with similar hardness
6. Limitations of High Carbon Steel
⚠️ Reduced Ductility – More brittle compared to low & medium carbon steels
⚠️ Difficult Welding – Requires preheating and post-treatment
⚠️ Lower Impact Resistance – Less suitable for shock loads
⚠️ Moderate Corrosion Resistance – Needs coatings, plating, or lubrication
7. Key Applications by Industry

8. Comparison with Other Steels & Metals
| Material | Strength | Hardness | Wear Resistance | Formability | Heat Treatable | Cost |
|---|---|---|---|---|---|---|
| Low Carbon Steel | Low | Low | Low | Excellent | No | Low |
| Medium Carbon Steel | Medium | Medium | Medium | Moderate | Yes | Medium |
| High Carbon Steel | High | Very High | Very High | Poor | Yes | Medium |
| Alloy Tool Steel | Very High | Very High | Very High | Poor | Yes | Higher |
| Stainless Steel | Medium | Medium | Medium | Moderate | Yes | High |
9. High Carbon Steel in the Carbon Steel Family
Low Carbon Steel (≤0.25% C): Highly ductile, weldable, low strength
Medium Carbon Steel (0.25–0.60% C): Balanced strength & ductility
High Carbon Steel (0.60–1.25% C): Maximum hardness & wear resistance, but brittle
High carbon steel is the hardest and most wear-resistant form of plain carbon steels, making it the preferred choice for knives, tools, and wear components.

It is ideal for knives, cutting tools, springs, wires, and components requiring extreme hardness.
Yes, but it requires preheating and post-weld heat treatment to avoid cracking.
Properly heat-treated grades can exceed 60 HRC, making them extremely hard.
Yes, without protective coatings it will oxidize. Surface treatments or stainless alloys are recommended in corrosive environments.
Absolutely, we supply tailor-made dimensions and pre-machined components.
