310S (UNS S31008) is an austenitic heat-resistant stainless steel optimized for cyclic thermal environments exceeding 1000°C. Its unique Cr/Ni ratio prevents sigma phase embrittlement while maintaining carburization resistance.
1. Critical Parameters Beyond Basic Composition
Table: Enhanced Property Profile
| Property | Value Range | Significance |
|---|---|---|
| Continuous Service Temp | ≤1150°C | Max oxidation-resistant limit |
| Cyclic Service Temp | ≤1200°C | Short-term exposure tolerance |
| Carburization Resistance | Excellent (up to 1050°C) | Critical for hydrocarbon processing |
| Sulfur Resistance | Good (≤650°C) | Suitable for flue gas systems |
| Thermal Shock | High resistance | Survives rapid quenching in furnaces |
2. Global Standards & Equivalents (Expanded)
Table: Tube Manufacturing Standards & Material Equivalents
| Region | Tube Standard | Material ID | Closest Alternatives | Key Difference |
|---|---|---|---|---|
| USA | ASTM A213/A312 | UNS S31008 | 310 (higher carbon) | 310S: C≤0.08% |
| Europe | EN 10216-5 | 1.4845 (X8CrNi25-21) | 253MA® (1.4835) | Lower Ni, add N/RE |
| Japan | JIS G3459 | SUS 310S | SUH310 (JIS) | Higher Si content |
| China | GB/T 14976 | 0Cr25Ni20 | 06Cr25Ni20 (GB) | Identical grade |
| India | IS 6911 | 10S310S | Esshete 1250® | Mo-enhanced |
Note: 310H (UNS S31009) with 0.04-0.10% C offers superior creep strength >550°C.
3. Specialized Applications by Industry
Table: Sector-Specific Implementations
| Industry | Component Examples | Failure Mode Addressed |
|---|---|---|
| Power Gen | Superheater tubes, HRSG manifolds | Steam-side oxidation @650°C+ |
| Chem/Petro | Ethylene cracker tubes, reformer pipes | Carburization/coking |
| Heat Treat | Muffle furnaces, retorts | Thermal fatigue cycling |
| Waste-to-Energy | Ash conveyor tubes, quench systems | Chloride-induced pitting |
| Food Proc | Fryer baskets, oven radiant tubes | Organic acid corrosion |
4. Advanced Packaging & Supply Specifications
Commercial Variants:
-
Seamless: ASTM A213 (high-pressure) | Welded: ASTM A312 (large diameters)
-
Surface Options:
-
AP (Annealed/Pickled): Standard mill finish
-
BA (Bright Annealed): Reflective finish for clean processes
-
EP (Electropolished): Ultra-smooth for high-purity systems
-
Packaging Protocols:
| Requirement | Industrial Grade | Nuclear/Aerospace Grade |
|---|---|---|
| Tube Ends | Plastic caps (single) | VCI foam + sealed caps |
| Surface Prot | Oiled or VCI paper | Double-layer VCI film |
| Bundling | Steel straps + timber skids | Non-metallic straps + crates |
| Traceability | Heat number stenciled | RFID tags + QR code etching |
5. Procurement Considerations
Critical Checks for Buyers:
-
Certification: EN 10204 3.1 vs. 3.2 (independent lab validation)
-
PMI Testing: Handheld XRF to verify Cr/Ni levels onsite
-
HTHA Resistance: Specify solution annealing at ≥1100°C
-
Weldability: Use AWS A5.9 ER310 filler wire
-
Alternatives: Consider Alloy 800H/RA330 for thermal cycling >1000°C
