Product Description Product Description 1. Material Composition & Mechanical Properties (Table)PropertyValueChemical CompositionCarbon (C): ≤0.030%, Chromium (Cr): 16.5-18.5%, Nickel (Ni): 10.0-13.0%, Molybdenum (Mo): 2.0-2.5%, Manganese (Mn): ≤2.0%, Silicon (Si): ≤1.0%, Phosphorus (P): ≤0.045%, Sulfur (S): ≤0.015%, Nitrogen (N): ≤0.11%Mechanical PropertiesTensile Strength: ≥485 MPa (70,300 psi) Yield Strength (Rp0.2): ≥170 MPa (24,600 psi) Heat TreatmentSolution-annealed at 1040-1100°C followed by rapid cooling (water quench) 2. Key ApplicationsChemical & Petrochemical: Corrosion-resistant piping for acids, chlorides, and aggressive media.Marine Environments: Seawater pipelines, offshore platforms, and desalination systems.Food & Beverage: Hygienic fluid transport due to non-reactive surface and cleanability.Pharmaceutical: High-purity process lines requiring resistance to sterilization and chemicals.Power Plants: Heat exchangers, condensers, and superheater tubes in corrosive/thermal conditions. 3. Manufacturing StandardsComplies with EN 10216-5: Seamless steel tubes for pressure purposes at elevated temperatures.Equivalent to ASTM A312/A312M TP316L and ASME SA312 for austenitic stainless steel pipes.Meets PED 2014/68/EU (Pressure Equipment Directive) for safety-critical applications. 4. Testing & CertificationHydrostatic Testing: Conducted per EN ISO 3458 to verify pressure integrity.Non-Destructive Testing (NDT): Eddy current, ultrasonic (UT), or dye penetrant inspection.Chemical Analysis: Verified via optical emission spectrometry (OES).Mechanical Testing: Tensile, hardness (HV), and impact testing (optional for low temps).Certifications: EN 10204 3.1/3.2 Mill Test Reports (MTRs), ISO 9001, and PED compliance. 5. AdvantagesSuperior Corrosion Resistance: Excellent resistance to pitting, crevice corrosion, and stress corrosion cracking (SCC) in chloride-rich environments.High-Temperature Stability: Maintains mechanical properties up to 400°C (750°F).Hygienic Surface: Ideal for sanitary applications with smooth, easy-to-clean finishes.Weldability: Compatible with TIG, MIG, and plasma welding methods without post-weld treatment.Low-Temperature Toughness: Suitable for cryogenic applications down to -196°C (-320°F). 6. Surface Finish & DimensionsSurface: Pickled, polished, or blasted finishes (Ra ≤0.8 μm for sanitary use).Sizes: Outer diameter 6-762 mm (0.24-30"), wall thickness 1-50 mm (0.039-1.97").
