Carbon Steel Fasteners derive their mechanical toughness from carbon content and trace alloying elements:
| Element | Grade 4.6 | Grade 8.8 | Grade 10.9 |
|---|---|---|---|
| Carbon (C) | 0.08–0.18% | 0.24–0.32% | 0.32–0.39% |
| Manganese (Mn) | 0.30–0.60% | 0.30–0.60% | 0.30–0.60% |
| Phosphorus (P) | ≤ 0.045% | ≤ 0.045% | ≤ 0.045% |
| Sulfur (S) | ≤ 0.045% | ≤ 0.045% | ≤ 0.045% |
| Silicon (Si) | ≤ 0.40% | ≤ 0.40% | ≤ 0.40% |
| Iron (Fe) | Balance | Balance | Balance |
| Property | Grade 4.6 | Grade 8.8 | Grade 10.9 |
|---|---|---|---|
| Tensile Strength (MPa) | 400–500 | 800–900 | 1,000–1,100 |
| Yield Strength (MPa) | 240 | 640 | 940 |
