Products Specification
| Product Name | 30CrMnSiA Alloy Steel Plate |
| Thickness | 10mm~200mm |
| Width | 1000~3000mm,common width is 1250mm,1500mm,2000mm,2200mm |
| Length | 1000~12000mm,can as your request cut |
| 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. |
| Feature | Benefit |
|---|---|
| High Strength-to-Weight Ratio | Enables lighter yet stronger structural designs |
| Excellent Low-Temperature Toughness | Maintains ductility down to –40°C; suitable for arctic or high-altitude use |
| Enhanced Wear & Abrasion Resistance | Chromium and manganese content improve surface durability |
| Good Hardenability | Achieves uniform hardness through thick cross-sections |
| Controlled Rolling Process | Reduces internal stresses and improves dimensional consistency |
| Custom Thickness Tolerances | ±0.3 mm achievable on select thicknesses (vs. standard ±1.0 mm) |
Note: While 30CrMnSiA offers strong mechanical properties in the as-rolled condition, optimal performance is achieved after quenching and tempering (Q&T). For welded structures, preheating (200–300°C) and post-weld heat treatment are strongly recommended.
| Element | Content (%) | Role in Performance |
|---|---|---|
| Carbon (C) | 0.28 – 0.34 | Provides core strength via martensitic transformation |
| Silicon (Si) | 0.90 – 1.20 | Enhances strength and deoxidizes molten steel |
| Manganese (Mn) | 0.80 – 1.10 | Increases hardenability and hot workability |
| Chromium (Cr) | 0.80 – 1.10 | Boosts wear resistance and deep-section hardening |
| Sulfur (S) | ≤ 0.025 | Minimized to prevent hot shortness |
| Phosphorus (P) | ≤ 0.025 | Controlled to avoid cold brittleness |
| Residual Elements (Ni, Cu, etc.) | ≤ 0.30 total | Kept low for weld integrity and purity |
| Property | Value | Standard |
|---|---|---|
| Tensile Strength (Rm) | 1080 – 1275 MPa | GB/T 228.1 |
