IN 10216-5 1.4404 (corresponding to UNS S31603) Und 1.4401 (corresponding to UNS S31600) Nahtlose Rohre aus Edelstahl are high-performance austenitic stainless steel pipes manufactured in accordance with the European standard IN 10216-5, specifically designed for high temperature, high pressure, and highly corrosive media environments. These two materials are widely used in industrial fields such as chemical, energy, shipbuilding, Pharmazeutika, and food processing due to their excellent corrosion resistance, mechanical strength, and processing performance.
Material characteristics
Chemical composition advantages
1.4404 (316L): Low carbon content (≤ 0.03% C), significantly reducing the risk of intergranular corrosion in welding and high-temperature environments.
1.4401 (316): Contains molybdenum (2.0-2.5% MO) to enhance resistance to pitting and crevice corrosion, suitable for general corrosive environments.
Main components: Cr (16.5-18.5%), In (10-13%), providing stable austenite structure and oxidation resistance.
Excellent mechanical performance
Tensile strength: ≥ 520 MPa
Yield strength: ≥ 210 MPa (annealed state)
Elongation rate: ≥ 40%, ensuring good plasticity and formability.
Corrosion resistance and high temperature resistance
Resistant to chlorides, organic acids, and weakly alkaline media, suitable for harsh environments such as seawater and chemical solutions.
Continuous operating temperature range: -196 ° C to+800 ° C (depending on specific operating conditions).
Manufacturing standards and processes
Standard compliance: Strictly follow EN 10216-5, covering chemical composition, mechanische Eigenschaften, non-destructive testing (ultrasonic/eddy current), and dimensional tolerance requirements.
Production process: Seamless pipes are manufactured using hot rolling or cold drawing processes to ensure smooth inner walls, uniform wall thickness, and no weak weld areas.
Testing and certification: Support third-party testing (such as T Ü V, SGS), provide material certificates (IN 10204 3.1/3.2), and comply with the Pressure Equipment Directive (PED 2014/68/EU).
Typical application areas
Chemical and petrochemical industries: reactors, heat exchanger pipelines, and corrosive fluid transport systems.
Energy and Environmental Protection: Power plant boiler tubes, flue gas desulfurization (FGD) devices, seawater desalination equipment.
Food and medicine: High cleanliness fluid transmission pipelines that comply with FDA/EC1935 hygiene standards.
Ship and ocean engineering: seawater cooling pipelines, ship hydraulic systems.
Product advantages
Reliability and lifespan: Seamless structure avoids leakage risks and extends equipment service life.
Multi functional processability:
supports secondary processing such as welding, bending, and expanding, adapting to complex installation requirements.
Green economy: 100% recyclable, in line with the concept of sustainable manufacturing.
