| Thickness tolerance | ±0.3mm |
| Application | It is mainly used to make structural parts such as car girder, beam, transmission shaft and car chassis parts, which can reduce the weight of the parts. |
Note: While 30CrMnSiA offers good mechanical properties, it is classified as a medium-carbon alloy steel, which means preheating is essential before welding to avoid cold cracking. Post-weld stress relief is also recommended for critical applications.
| Element | Content (%) | Role in Performance |
|---|---|---|
| Carbon (C) | 0.28 – 0.34 | Provides core strength and hardness through martensitic transformation |
| Silicon (Si) | 0.90 – 1.20 | Enhances strength via solid solution strengthening; improves oxidation resistance |
| Manganese (Mn) | 0.80 – 1.10 | Increases hardenability and tensile strength; improves hot workability |
| Chromium (Cr) | 0.80 – 1.10 | Boosts hardenability, wear resistance, and corrosion resistance |
| Sulfur (S) | ≤ 0.025 | Strictly controlled to minimize hot shortness |
| Phosphorus (P) | ≤ 0.025 | Limited to prevent cold brittleness |
| Nickel (Ni) | ≤ 0.030 | Residual; kept low to maintain cost and performance balance |
| Copper (Cu) | ≤ 0.025 | Residual; controlled to avoid surface defects |
| Property | Value | Test Standard |
|---|---|---|
| Tensile Strength (σb) | ≥ 1080 MPa | GB/T 228.1 |
| Yield Strength (σs) | ≥ 835 MPa | GB/T 228.1 |
| Elongation (δ5) | ≥ 10% | GB/T 228.1 |
| Reduction of Area (ψ) | ≥ 45% | GB/T 228.1 |
| Impact Toughness (Akv, 20°C) | ≥ 39 J | GB/T 229 |
| Impact Toughness (Akv, -40°C) | ≥ 88 J (premium grade) | GB/T 229 |
| Hardness (HB) | ≤ 229 (as-rolled); 24–32 HRC (after Q&T) | GB/T 231.1 |
