| 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. |
| Element | Content (%) | Metallurgical Role |
|---|---|---|
| Carbon (C) | 0.28 – 0.34 | Enables martensite formation during quenching |
| Silicon (Si) | 0.90 – 1.20 | Strengthens ferrite; improves oxidation resistance |
| Manganese (Mn) | 0.80 – 1.10 | Enhances hardenability and hot ductility |
| Chromium (Cr) | 0.80 – 1.10 | Increases hardenability, wear resistance, and temper stability |
| Sulfur (S) | ≤ 0.025 | Minimized to avoid hot shortness |
| Phosphorus (P) | ≤ 0.025 | Controlled to prevent cold brittleness |
| Residuals (Ni, Cu, etc.) | ≤ 0.30 total | Kept low for weldability and purity |
| Property | Typical Value | Test Standard |
|---|---|---|
| Tensile Strength (Rm) | 1080 – 1275 MPa | GB/T 228.1 |
| Yield Strength (Rp0.2) | ≥ 835 MPa | GB/T 228.1 |
| Elongation (A5) | ≥ 10% | GB/T 228.1 |
| Reduction of Area (Z) | ≥ 45% | GB/T 228.1 |
| Impact Energy (20°C) | ≥ 39 J | GB/T 229 |
| Impact Energy (–40°C) | ≥ 88 J (premium grade) | GB/T 229 |
| Hardness | 24 – 32 HRC | ISO 6508 / GB/T 230.1 |
Note: Properties are optimized for plates ≤100 mm thick. For sections >150 mm, slight reductions in through-thickness hardness may occur but remain within specification.
