    Incoloy 840 Nickel Based Seamless Pipe For For Low Temperature Environment

    Incoloy 840 Nickel Based Seamless Pipe For For Low Temperature Environment

    Incoloy 840 is an austenitic nickel-chromium-iron alloy specially formulated for both high-temperature corrosion resistance and excellent low-temperature toughness, making it ideal for seamless pipe applications down to cryogenic conditions. Typical pipe sizes range from ½" to 24" OD with wall thicknesses from 0.035" to 0.5", supplied per major international standards. Below are detailed specifications, comparative composition and mechanical tables for five similar nickel-based alloys, key features, conformity standards across ASTM/EN/GOST/JIS/GB, and primary application domains with specific uses.

    Material

    Incoloy 840 is a nickel-chromium-iron-based austenitic alloy, with controlled additions of titanium and aluminum for precipitation strengthening. Its balanced chemistry delivers superb corrosion resistance in both oxidizing and reducing environments, while maintaining ductility at temperatures as low as –196 °C

    Main Features

    • Cryogenic Toughness: Maintains ductility down to –196 °C.

    • Corrosion Resistance: Resistant to chloride stress-corrosion cracking, pitting, and crevice attack.

    • Oxidation Resistance: Forms stable oxide scale up to ~1 000 °C.

    • Precipitation Strengthening: Ti and Al additions deliver enhanced strength vs. standard austenitics.

    • Fabricability: Readily weldable and formable; seamless condition minimizes impurity ingress.

    Execution Standards

    • ASTM/ASME: B163/B423 (pipe), B407/B409 (tube), B424 (heat-exchanger tube); ASME SB-163/SB-423, SB-407/SB-409, SB-424.

    • EN: EN 10216-5 (nickel alloys, seamless tubes), EN 10204 3.1 certification.

    • GOST: GOST 9940-81 (nickel alloys tubes).

    • JIS: JIS G3459 (nickel alloy tubes for heat exchangers).

    • GB: GB/T 14975 (seamless steel pipes for high-temperature service).

    Application Fields

    1. Petrochemical & Chemical Processing

    • Use: Process piping, reactors, heat exchangers, pickling tanks.

    • Why: Withstands acidic/alkaline media and cyclic temperatures.

    2. Cryogenic & Low-Temperature Systems

    • Use: LNG storage and transfer lines, refrigerated process headers.

    • Why: Exceptional low-temp toughness and minimal ductile-brittle transition.

    3. Power Generation

    • Use: Superheater/reheater tubes, boiler piping.

    • Why: High-temperature strength and oxidation resistance enable stable long-term service.

    4. Marine & Offshore

    • Use: Seawater cooling lines, exhaust stacks, fluid transportation.

    • Why: Pitting and crevice corrosion resistance in saline environments.

    5. Food & Pharmaceutical Equipment

    • Use: Process piping, heat exchangers, sterilization systems.

    • Why: Cleanliness, corrosion resistance, and weldability ensure hygienic operation.
