Introduction to 310S Stainless Steel Tubing
310S stainless steel tubing is a high-alloy austenitic stainless steel specifically designed for exceptional resistance to oxidation (scaling) and corrosion at elevated temperatures. It is the low-carbon version of the basic 310 alloy, which significantly enhances its suitability for high-temperature applications by minimizing carbide precipitation during welding or exposure in the critical temperature range (800°F - 1500°F / 427°C - 816°C).
Key Parameters & Chemical Composition:
Common Grades: UNS S31008, AISI 310S, EN 1.4845
Chemical Composition (Typical Weight %):
Carbon (C): ≤ 0.08% (Low carbon for improved weldability & high-temp stability)
Chromium (Cr): 24.0 - 26.0% (Provides primary oxidation resistance)
Nickel (Ni): 19.0 - 22.0% (Stabilizes austenitic structure, enhances ductility & corrosion resistance)
Manganese (Mn): ≤ 2.00%
Silicon (Si): ≤ 1.50%
Phosphorus (P): ≤ 0.045%
Sulfur (S): ≤ 0.030%
Iron (Fe): Balance
Density: 7.98 g/cm³ (0.288 lb/in³)
Melting Point: ~1400°C - 1450°C (2550°F - 2640°F)
Continuous Service Temperature: Up to 1150°C (2100°F) in oxidizing atmospheres. Intermittent use up to 1035°C (1900°F).
Thermal Expansion: Relatively high (comparable to other austenitics like 304), ~16-18 μm/m·°C (20-100°C).
Thermal Conductivity: ~14 W/m·K (at 100°C).
Electrical Resistivity: ~0.85 μΩ·m.
Magnetic Properties: Essentially non-magnetic (austenitic structure).
Common Standards & Specifications:
310S tubing is manufactured to meet various international standards depending on dimensions, tolerances, testing, and intended use. Key standards include:
ASTM (American Society for Testing and Materials):
A213/A213M: Specification for Seamless Ferritic and Austenitic Alloy-Steel Boiler, Superheater, and Heat-Exchanger Tubes.
A269/A269M: Specification for Seamless and Welded Austenitic Stainless Steel Tubing for General Service.
A312/A312M: Specification for Seamless, Welded, and Heavily Cold Worked Austenitic Stainless Steel Pipes. (Often covers larger diameters/pipes).
A789/A789M: Specification for Seamless and Welded Ferritic/Austenitic Stainless Steel Tubing for General Service.
ASME (American Society of Mechanical Engineers): SA213, SA269, SA312, SA789 (Often identical to ASTM specs but adopted for Boiler & Pressure Vessel Code use).
EN (European Norm):
EN 10216-5: Seamless steel tubes for pressure purposes - Technical delivery conditions - Part 5: Stainless steel tubes.
EN 10296-2: Welded circular steel tubes for mechanical and general engineering purposes - Technical delivery conditions - Part 2: Stainless steel.
DIN (Deutsches Institut für Normung): DIN 17458 (Seamless circular tubes), DIN 17456 (Welded circular tubes).
JIS (Japanese Industrial Standards): JIS G 3463 (Stainless steel boiler and heat exchanger tubes), JIS G 3459 (Stainless steel pipes).
GOST (Russian Standards): GOST 9941 (Seamless hot-deformed tubes), GOST 11068 (Welded tubes).
Key Advantages:
Outstanding High-Temperature Oxidation Resistance: The high chromium (Cr) and nickel (Ni) content forms a stable, protective chromium oxide (Cr₂O₃) scale, preventing further oxidation even under severe cyclic heating conditions up to 1150°C (2100°F).
Excellent Carburization Resistance: Performs well in carburizing atmospheres compared to lower alloyed stainless steels.
Good Sulfidation Resistance: Offers reasonable resistance to sulfur-containing atmospheres at high temperatures.
Good Creep & Rupture Strength: Maintains strength better than standard austenitic grades (like 304/316) at sustained high temperatures.
Corrosion Resistance: Excellent general corrosion resistance in many aqueous environments (similar to 304/304L), and superior pitting/crevice corrosion resistance compared to 304 due to higher Cr & Ni. Resists nitric acid well.
Low Carbon Content (310S): Minimizes sensitization (chromium carbide precipitation at grain boundaries) during welding or high-temperature exposure, preventing intergranular corrosion and maintaining ductility. This is the key difference vs. 310.
Formability & Weldability: Good formability and weldability (using standard austenitic procedures like TIG, MIG, SAW), though its high strength can require more force for forming. Post-weld annealing is generally not required due to low carbon content.
Typical Packaging:
Packaging aims to protect the tubing surface from damage, scratching, and corrosion during handling, storage, and transport. Common methods include:
Bundling: Tubes are securely strapped together (plastic or steel bands) into bundles.
End Protection: Plastic or metal end caps are often fitted to protect tube ends and threads (if present).
Wrapping: Bundles may be wrapped in:
Waterproof Paper / VCI Paper: Protects against moisture and provides basic physical protection. VCI (Vapor Corrosion Inhibitor) paper releases corrosion-inhibiting vapors.
Plastic Shrink Wrap / Polyethylene Film: Provides a moisture barrier and good physical protection.
Hessian / Burlap: Sometimes used over wrap for additional abrasion resistance (less common now).
Wooden Crates / Pallets: Bundles are placed on sturdy wooden pallets or enclosed within wooden crates for heavy loads, long-term storage, or demanding transport (especially sea freight). Wood must often comply with ISPM 15 for international shipping.
Identification: Each bundle or crate is clearly labeled with material grade (310S), size, length, heat number, quantity, standard, manufacturer, and other relevant order information.
Primary Applications:
310S tubing excels in environments involving high temperatures and corrosive atmospheres:
Furnace Components: Radiant tubes, muffles, retorts, combustion tubes, thermowells, burner nozzles, furnace conveyors, annealing covers.
Heat Exchangers & Boilers: Tubing for superheaters, reheaters, heat recovery systems, and other components in high-temperature, corrosive service (especially where oxidation resistance is paramount).
Chemical & Petrochemical Processing: Tubing in reactors, reformers, crackers, and piping systems handling hot corrosive gases, acids (like nitric), and catalysts.
Power Generation: Boiler tubes, superheater tubes, and other high-temperature components in fossil fuel and waste-to-energy plants.
Heat Treating Equipment: Fixtures, baskets, trays, and furnace internals exposed to repeated high temperatures.
Aerospace: Certain high-temperature exhaust components and engine parts.
Food Processing: Equipment requiring high-temperature sterilization and good corrosion resistance.
Kilns & Incinerators: Structural components and tubing exposed to high heat and combustion gases.
