Product Description Product DescriptionASTM A268 TP446 and TP410 Stainless Steel Welded Pipe Specification Specification AspectASTM A268 TP446 Welded PipeASTM A268 TP410 Welded PipeMaterial Composition- Chromium (Cr): ~26-29% (enhances high-temperature oxidation resistance).- Other elements (e.g., Mo, Ni) vary per UNS S44600 standard.- Chromium (Cr): 11.5-13.5%- Carbon (C): ≤0.15%- Manganese (Mn): ≤1.00%- Silicon (Si): ≤1.00%Mechanical Properties- Tensile Strength: ≥515 MPa- Yield Strength: ≥205 MPa- Elongation: ≥20%- Hardness: ≤207 HB- Tensile Strength: ≥415 MPa- Yield Strength: ≥205 MPa- Elongation: ≥20%- Hardness: ≤207 HBCorrosion Resistance- Excellent resistance to high-temperature scaling and oxidation.- Suitable for sulfurous environments.- Moderate corrosion resistance in mild conditions; improved via heat treatment (e.g., quenching).Applications- Petrochemical and power plant equipment (e.g., boilers, superheaters).- High-temperature, non-chloride aggressive environments.- Automotive exhaust systems, kitchenware, industrial machinery, and components requiring moderate corrosion resistance.Manufacturing StandardASTM A268/A268M (seamless/welded ferritic/martensitic stainless steel tubing for general service).Same as TP446.Size Range- OD: 6.35 mm (1/4") to 203 mm (8").- Wall Thickness: 0.5 mm to 12.7 mm.- OD: 19.05 mm to 76.2 mm.- Wall Thickness: 0.5 mm to 12.7 mm.Surface Finish- Annealed and pickled (standard).- Optional: Bright polished or custom finishes.- Annealed and pickled; may be polished for aesthetics or functional requirements.Testing Requirements- Hydrostatic/nondestructive testing.- Mechanical tests (tension, flattening, flaring).- Third-party inspection available.- Hydrostatic testing, chemical analysis, and hardness testing.- PMI (Positive Material Identification).Delivery Conditions- Annealed and pickled (default).- Lengths up to 24 meters.- Annealed and pickled; lengths up to 24 meters.Key Characteristics- Ferritic structure with high chromium content for heat resistance.- Non-hardening via heat treatment.- Martensitic structure, hardenable via quenching and tempering.- Magnetic and weldable with precautions. ASTM A268 TP446 Stainless Steel Welded Pipe Advantages Advantage AspectDetailsHigh-Temperature Resistance- Exceptional oxidation and scaling resistance at elevated temperatures (up to 1100°C).- Suitable for sulfur-rich environments (e.g., petrochemical boilers).Corrosion Resistance- Resistant to nitric acid, organic acids, and alkaline solutions.- Non-hardening structure minimizes stress corrosion cracking.Mechanical Stability- Maintains strength and ductility at high temperatures (e.g., for superheater tubes).Cost-Effectiveness- Lower cost than austenitic grades (e.g., 316) due to reduced nickel/molybdenum content.Weldability- Easily welded with standard methods (TIG/MIG) without post-weld heat treatment.Non-Magnetic Properties- Ferritic structure ensures non-magnetic behavior for sensitive applications.Design Flexibility- Available in diverse sizes (OD: 6.35-203 mm) for versatile industrial installations. ASTM A268 TP410 Stainless Steel Welded Pipe Advantages Advantage AspectDetailsHardenability- Martensitic structure allows hardening via quenching and tempering (e.g., up to ~45 HRC).Mechanical Strength- High tensile strength (≥415 MPa) and wear resistance for demanding mechanical applications.Corrosion Resistance- Moderate resistance to atmospheric corrosion, steam, and mild chemicals (e.g., food processing).Magnetic Properties- Magnetic behavior suitable for applications requiring magnetic retention or separation.Weldability with Caution- Weldable with proper pre/post-weld heat treatment to prevent embrittlement.Surface Finish Options- Polished finishes enhance aesthetics and reduce contamination buildup (e.g., kitchenware).Cost-Effective Performance- Balances corrosion resistance and mechanical strength at a lower cost than higher-alloy grades. TP446 prioritizes high-temperature oxidation resistance and sulfur tolerance.TP410 offers hardenability and wear resistance for applications needing structural robustness.
