2. What is What is Low Carbon Steel?
Low carbon steel, often called mild steel, contains typically 0.05% – 0.25% carbon by weight.
The low carbon content makes it softer, more ductile, and easier to shape compared to higher-carbon steels. It’s the most widely used steel category for construction, automotive, machinery, and general fabrication.
3. Physical Properties of Low Carbon Steel
| Property | Typical Value |
|---|---|
| Density | 7.85 g/cm³ |
| Melting Point | 1,425 – 1,538°C |
| Thermal Conductivity | ~54 W/m·K |
| Electrical Resistivity | 0.15 μΩ·m |
| Magnetic Properties | Ferromagnetic |
4. Mechanical Properties of Low Carbon Steel
| Property | Typical Range |
|---|---|
| Yield Strength | 200 – 350 MPa |
| Tensile Strength | 370 – 500 MPa |
| Elongation (A80) | 25 – 40% |
| Hardness (HB) | 120 – 180 |
| Impact Toughness | High |
5. Advantages of Low Carbon Steel
Excellent Weldability – Suitable for arc, MIG, TIG, and spot welding.
High Ductility – Can be bent, rolled, and formed easily.
Good Machinability – Reduces tool wear during processing.
Cost-Effective – Affordable compared to high-carbon steels or alloys.
Surface Treatment Compatibility – Easily galvanized, painted, or coated.
6. Limitations of Low Carbon Steel
Low Strength Compared to Alloy Steels – Not ideal for high-load structural parts without reinforcement.
Low Wear Resistance – Can be prone to abrasion in demanding applications.
Low Corrosion Resistance – Requires protective coatings in outdoor environments.
7. Applications by Industry

8. Comparison with Other Steels & Metals
| Material | Strength | Corrosion Resistance | Formability | Cost |
|---|---|---|---|---|
| Low Carbon Steel | Low-Medium | Low (needs coating) | Excellent | Low |
| Medium Carbon Steel | Medium | Low | Good | Medium |
| High Carbon Steel | High | Low | Poor | Medium |
| Stainless Steel | Medium-High | Excellent | Moderate | High |
| Aluminum Alloy | Low-Medium | Excellent | Good | Medium |
9. Low Carbon Steel vs. Other Carbon Steels
From a metallurgical perspective:
Low Carbon Steel (≤0.25% C) → Best for welding & forming
Medium Carbon Steel (0.25–0.60% C) → Stronger, less ductile
High Carbon Steel (>0.60% C) → Hard, brittle, used for cutting tools
Huaxiao-Alloy’s low carbon steel is carefully controlled for uniform grain structure, ensuring predictable performance in demanding forming processes.
