| Surface | Clean,finished, blasting and painting or as your request |
| Delivery | Hot Rolled, Controlled Rolling,Normalizing,Annealing, Tempering,Quanching, Q+T |
| Packing | Steel Strapping,fixing in the Container,can customize |
| 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. |
| Attribute | Benefit in Critical Applications |
|---|---|
| Tensile Strength ≥1080 MPa | Supports high-load structures without excessive mass |
| High Hardenability | Enables uniform through-thickness properties in thick sections |
| Good Low-Temperature Toughness | Maintains ductility down to –40°C (critical for high-altitude or arctic operations) |
| Controlled Impurity Levels | Ultra-low S/P content minimizes crack risk in welded or forged parts |
| Excellent Machinability (after annealing) | Facilitates complex component fabrication with tight tolerances |
| Proven Track Record | Widely used in Chinese fighter jets, armored vehicles, and missile systems |
⚠️ Note: Due to its medium-carbon composition, welding requires preheating (200–300°C) and post-weld stress relief to prevent hydrogen-induced cracking.
| Element | Content (%) | Purpose |
|---|---|---|
| Carbon (C) | 0.28 – 0.34 | Core strength via martensite formation |
| Silicon (Si) | 0.90 – 1.20 | Solid-solution strengthening; deoxidizer |
| Manganese (Mn) | 0.80 – 1.10 | Enhances hardenability and hot workability |
| Chromium (Cr) | 0.80 – 1.10 | Improves wear resistance and deep hardening |
| 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 purity and weld integrity |
| 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 (Q&T); ≤229 HB (as-rolled) | GB/T 231.1 / ISO 6508 |
