1. Introduction: The Backbone of Modern Industry
Carbon steel accounts for the majority of steel used in the world today. From construction beams to automobile components and precision cutting tools, carbon steel’s versatility makes it indispensable. But not all carbon steel is created equal. The amount of carbon determines its hardness, ductility, and applications.
At Huaxiao-Alloy, we supply low, medium, and high carbon steels in multiple forms and standards, serving clients across Europe, North America, and beyond. If you’re looking for a complete guide to carbon steel grades, performance, and applications, you’ve found it. This article is designed to be your one-stop reference—clear, professional, and actionable.
2. Quick Comparison: Low vs Medium vs High Carbon Steel
| Steel Type | Carbon % | Strength | Ductility | Weldability | Wear Resistance | Typical Applications |
|---|---|---|---|---|---|---|
| Low Carbon Steel | ≤0.25% | Low (400–600 MPa) | Excellent | Excellent | Low | Structural beams, pipelines, car panels |
| Medium Carbon Steel | 0.25–0.60% | Medium (600–900 MPa) | Moderate | Moderate | Medium | Axles, gears, crankshafts, machinery |
| High Carbon Steel | 0.60–1.25% | High (900–1500 MPa) | Low | Poor | Very High | Knives, springs, blades, dies |
Low vs Medium vs High Carbon Steel Summary:
Choose low carbon steel when cost, weldability, and ductility are top priorities.
Opt for medium carbon steel when you need balanced strength and machinability.
Select high carbon steel for maximum hardness and wear resistance.

| High Carbon Steel | 0.60–1.25% | AISI 1065/1080, EN C75, JIS SK5 | Strips, wires, blades, plates |
4. Mechanical & Physical Properties - Low vs Medium vs High Carbon Steel
| Property | Low Carbon Steel | Medium Carbon Steel | High Carbon Steel |
| Tensile Strength MPa | 400–600 | 600–900 | 900–1500 |
| Hardness (HB) | 120–180 | 170–250 | 250–600 |
| Ductility | High | Medium | Low |
| Weldability | Excellent | Moderate | Poor |
| Density | ~7.85 g/cm³ | ~7.85 g/cm³ | ~7.85 g/cm³ |
5. Advantages & Limitations: Side by Side - Low vs Medium vs High Carbon Steel
| Steel Type | Advantages | Limitations |
| Low Carbon Steel | Cost-effective, easy to weld, highly formable | Low strength, poor wear resistance |
| Medium Carbon Steel | Balanced strength/ductility, heat-treatable | Less weldable, requires controlled processing |
| High Carbon Steel | Very hard, excellent wear resistance | Brittle, difficult to weld, less ductile |
6. Applications Across Industries - Low vs Medium vs High Carbon Steel
Low Carbon Steel: construction beams, pipelines, automotive body panels, tanks.
Medium Carbon Steel: gears, axles, railway parts, machinery, pressure vessels.
High Carbon Steel: knives, cutting tools, springs, dies, wear-resistant components.
7. Carbon Steel vs Other Metals
Vs Stainless Steel: Stainless is corrosion-resistant but more expensive. Carbon steel offers superior strength-to-cost ratio.
Vs Alloy Steel: Alloy steel has specialized properties with Cr, Ni, Mo. Carbon steel is simpler and more economical.
Vs Aluminum: Aluminum is lightweight and corrosion-resistant, but far weaker than carbon steel in structural applications.
