| Applications: | fluid and gas transport, structure , boiler, heat exchanger, super heater |
| Element | Content Range (%) | Function |
|---|---|---|
| Chromium (Cr) | 18.0–20.0 | Forms a passive oxide layer, preventing rust and corrosion. |
| Nickel (Ni) | 8.0–10.5 | Stabilizes the austenitic structure, enhancing ductility and toughness. |
| Carbon (C) | ≤0.08 | Adds strength but is limited to avoid carbide precipitation during welding. |
| Manganese (Mn) | ≤2.0 | Aids in deoxidation and improves workability. |
| Silicon (Si) | ≤1.0 | Enhances high-temperature oxidation resistance. |
| Phosphorus (P) | ≤0.045 | Controlled to prevent brittleness. |
| Sulfur (S) | ≤0.03 | Minimized to maintain weldability and corrosion resistance. |
| Property | Typical Value | Test Standard |
|---|---|---|
| Tensile Strength | 515–690 MPa | ASTM E8 / EN 10002-1 |
| Yield Strength (0.2% offset) | ≥205 MPa | ASTM E8 / EN 10002-1 |
| Elongation (in 50mm) | ≥40% | ASTM E8 / EN 10002-1 |
| Hardness (Brinell) | ≤201 HB | ASTM E10 / EN ISO 6506-1 |
| Modulus of Elasticity | ~193 GPa | - |
| Density | 8.0 g/cm³ | - |
| Standard | Issuing Body | Application |
|---|---|---|
| ASTM A554 | ASTM International | Welded stainless steel mechanical tubing |
| EN 10217-7 | European Committee | Welded tubes for pressure (stainless steel) |
| JIS G3446 | Japanese Industrial Standards | Stainless steel square tubes |
| GB/T 12771 | China National Standard | Welded stainless steel pipes |
| Grade | Key Difference from 304 | Best For |
|---|---|---|
| 304L | Lower carbon (≤0.03%) to reduce carbide precipitation | Welded structures requiring maximum corrosion resistance. |
| 316 | Contains molybdenum (2–3%) for better chloride resistance | Marine, coastal, or high-salt environments. |
| 303 | Higher sulfur for improved machinability | Parts requiring intricate machining (e.g., fasteners). |
| 430 | Ferritic (no nickel); lower cost but less corrosion resistance | Dry, indoor applications (e.g., appliance trim). |
