ASTM A240 310S Stainless Steel Sheet – Ideal for Furnace and Heat Treatment Equipment
Product Overview
Manufactured to the rigorous requirements of ASTM A240/A240M, 310S stainless steel sheet is a high-alloy austenitic material specifically engineered for extreme-temperature industrial applications. With exceptional resistance to oxidation, scaling, and thermal fatigue up to 1150°C (2100°F), it is the material of choice for furnace components, heat treatment fixtures, radiant tubes, muffles, retorts, and other critical high-heat equipment.
The “S” in 310S denotes ultra-low carbon content (≤0.08%), which prevents chromium carbide precipitation during prolonged exposure to elevated temperatures—ensuring long-term corrosion and oxidation resistance, even in welded or thermally cycled conditions. Compliant with global standards including UNS S31008, EN 1.4845, and JIS SUS310S, this ASTM-certified sheet delivers consistent metallurgical quality, traceability, and performance for mission-critical thermal systems.
Available in cold-rolled or hot-rolled forms with thicknesses from 0.5 mm to 12.0 mm, 310S sheet combines fabricability with unmatched high-temperature durability.
Why ASTM A240 Compliance Matters
ASTM A240 is the standard specification for chromium and chromium-nickel stainless steel plate, sheet, and strip for pressure vessels and general applications. Compliance ensures:
- Strict control of chemical composition (Cr, Ni, C, etc.)
- Verified mechanical properties (tensile strength, yield, elongation)
- Uniform heat treatment (solution annealing and rapid cooling)
- Full traceability via Mill Test Report (EN 10204 3.1)
- Suitability for ASME BPVC Section II and PED applications
This certification guarantees that every coil or sheet meets the exacting demands of industrial furnace builders and heat-treatment engineers worldwide.
Key Advantages for Furnace & Heat Treatment Use
| Feature | Benefit in Thermal Applications |
|---|---|
| Oxidation Resistance up to 1150°C | Forms stable Cr₂O₃ scale; minimal spalling or metal loss |
| Low Carbon (≤0.08%) | Prevents sensitization—ideal for welded assemblies in continuous service |
| High Chromium (25%) & Nickel (20%) | Maintains austenitic structure and ductility at red-hot temperatures |
| Excellent Thermal Fatigue Resistance | Withstands repeated heating/cooling cycles without cracking |
| Good Creep Strength | Retains load-bearing capacity under stress at >900°C |
| Non-Magnetic (Annealed) | Compatible with instrumentation and non-ferrous handling systems |

Typical Applications in Heat Processing
✅ Furnace Components
- Muffles, retorts, hearth plates, burner nozzles
- Radiant tubes, flame shields, expansion joints
✅ Heat Treatment Fixtures
- Baskets, trays, grids, racks for carburizing, annealing, or hardening
- Sintering boats and support rails
✅ Industrial Systems
- Exhaust manifolds in thermal oxidizers
- Ducting for hot flue gases
- Kiln furniture in ceramic and cement industries
Fabrication Recommendations
- Cutting: Laser, plasma, or waterjet preferred. Avoid abrasive methods that embed iron.
- Forming: Excellent cold formability for thin gauges (<3 mm). For thicker sections, warm forming (600–900°C) may be used.
- Welding:
- Use ER310 or ER312 filler metals.
- No preheat required; keep interpass temperature <150°C.
- Post-weld annealing not needed due to low carbon.
- Machining: Use sharp tools, slow speeds, and ample coolant—310S work-hardens rapidly.
Surface Finish Options & Protection
| Finish | Description | Best For |
|---|---|---|
| 2B | Smooth, semi-reflective (cold-rolled + annealed) | General fabrication, moderate temp |
| No.1 | Hot-rolled, annealed, pickled—matte texture | High-temp forming, furnace interiors |
| BA (Bright Annealed) | Mirror-like, oxide-free surface | Applications requiring minimal scale formation |
All sheets typically include a removable PVC film to protect the surface during shipping and handling.
Quality Assurance & Documentation
Each batch includes:
- Mill Test Report (MTR) per EN 10204 3.1
- PMI (Positive Material Identification) available on request
- UT (Ultrasonic Testing) for critical thicknesses
- Full compliance with ASTM A240 chemical & mechanical limits
Why Choose 310S Over Other Grades?
| Grade | Max Temp | Oxidation Resistance | Cost | Furnace Suitability |
|---|---|---|---|---|
| 304 | 870°C | Moderate | $ | ❌ Not recommended |
| 316L | 870°C | Moderate (better in chlorides) | $$ | ❌ Unsuitable |
| 309S | 1000°C | Good | $$ | ✅ For lower-temp zones |
| 310S | 1150°C | Excellent | $$$ | ✅✅✅ Optimal choice |
| Inconel 600 | 1150°C | Excellent | $$$$$ | ✅ Overkill for many applications |
