310S Austenitic Stainless Steel Hot-Rolled Thick Plate
- High-Temperature Resistance:Excellent oxidation resistance up to 1100°C due to high chromium (Cr) and nickel (Ni) content.
- Corrosion Resistance:Superior performance in acidic, alkaline, and chloride environments.
- Mechanical Strength:Maintains structural integrity under thermal stress and mechanical loads.
- Weldability:Low carbon content minimizes carbide precipitation, ensuring consistent weld quality.
Chemical Composition (wt%)
Element | Content (%) | Role |
C (Carbon) | ≤0.08 | Enhances hardness; controlled to avoid weld brittleness |
Si (Silicon) | ≤1.00 | Improves strength; excess reduces ductility |
Mn (Manganese) | ≤2.00 | Enhances toughness and hot workability |
P (Phosphorus) | ≤0.045 | Harmful impurity; limited to prevent brittleness |
S (Sulfur) | ≤0.030 | Minimized to avoid hot cracking |
Cr (Chromium) | 24.0–26.0 | Forms oxidation-resistant passive layer |
Ni (Nickel) | 19.0–22.0 | Stabilizes austenitic structure; improves corrosion resistance |
Others (Mo, Cu) | Trace | Optional for specific corrosion/strength needs |
