Nickel Alloy Pipes Manufacturer & Exporter

Leoscor Alloys Pipes stocks nickel alloy pipes in Mumbai and ships them to buyers across the Middle East, Southeast Asia and Africa. We hold ASTM B161, B163, B167, B444, B407, B622 and B729 material in Nickel 200, Nickel 201, Inconel 600, 601 and 625, Incoloy 800, 800H, 800HT and 825, Monel 400, Hastelloy C276, C22 and B2, and Alloy 20, in sizes from NPS 1/2″ up to 24″, in seamless and welded forms. Every length leaves our warehouse with an EN 10204 3.1 mill test certificate and a traceable heat number.

Nickel alloys are specified when stainless and duplex steel are not enough — hydrochloric acid, wet chlorine, caustic soda above 100°C, or sustained service above 600°C. Each alloy family is built for a different failure mode: the Hastelloy range resists the harshest acids in both oxidising and reducing conditions, Inconel holds up at extreme temperatures and against chloride stress corrosion cracking, Incoloy resists carburising and oxidising furnace atmospheres, Monel is built for seawater and hydrofluoric acid, and Alloy 20 was developed specifically for sulphuric acid.

Our Nickel Alloy Seamless Pipes are manufactured to ASTM B161 / B163 / B167 / B444 / B407 / B622 / B729, and our Nickel Alloy Welded Pipes follow ASTM B358 / B464 / B619 / B704 / B725 / B751. Both forms are available in round sections as standard, with square, rectangular and hexagonal profiles available on request. For queries on grade selection or availability, send us a query.

    Choosing the right nickel alloy

    Nickel alloys are not ranked on one scale the way stainless grades are compared on PREN. Each family was developed for a different attack mechanism — acid type, temperature, or oxidising versus reducing conditions. Picking the wrong family here is expensive, so this is the shortcut our team uses when a customer describes the service condition.

    Alloy UNS Family Pick it when
    Nickel 200 N02200 Commercially pure nickel Caustic soda and alkali service below 315°C. High thermal and electrical conductivity needed.
    Nickel 201 N02201 Commercially pure nickel, low carbon Same duty as Nickel 200 but above 315°C. Low carbon avoids graphitisation at sustained high temperature.
    Inconel 600 N06600 Ni-Cr-Fe Continuous service to 1150°C. Resists chloride-ion stress corrosion cracking where 304/316 would crack.
    Inconel 601 N06601 Ni-Cr-Al Sustained oxidation resistance above 1150°C, up to 1200°C. The aluminium addition outperforms 600 at the extreme end.
    Inconel 625 N06625 Ni-Cr-Mo-Nb You need high strength and corrosion resistance together — offshore, marine, cryogenic to high temperature.
    Incoloy 800 N08800 Fe-Ni-Cr Furnace and heat-treatment equipment up to 800-900°C. Resists carburising and oxidising atmospheres.
    Incoloy 800H N08810 Fe-Ni-Cr, controlled grain Same duty as 800 but sustained above 600°C, where creep-rupture strength matters — reformer tubes, ethylene furnaces.
    Incoloy 800HT N08811 Fe-Ni-Cr, Al+Ti controlled Highest temperature capability in the 800 series. Reformer and pyrolysis service above 900°C.
    Incoloy 825 N08825 Ni-Fe-Cr-Mo-Cu Sulphuric and phosphoric acid, sour oil and gas service. Molybdenum plus copper outperform 904L in reducing acids.
    Monel 400 N04400 Ni-Cu Seawater and marine hardware. Also resists hydrofluoric acid and non-oxidising acids like HCl without oxidising contaminants.
    Hastelloy C276 N10276 Ni-Mo-Cr You are not sure what is in the fluid. Resists wet chlorine, hypochlorite and mixed acids in both oxidising and reducing conditions.
    Hastelloy C22 N06022 Ni-Cr-Mo-W Ferric or cupric chloride, mixed oxidising acids. Higher chromium than C276 gives better performance and weldability here.
    Hastelloy B2 N10665 Ni-Mo Pure hydrochloric acid at any concentration — but only where the process is reducing. Do not use where oxidising ions (ferric, cupric, dissolved oxygen) are present.
    Alloy 20 N08020 Ni-Fe-Cr-Mo-Cu Sulphuric acid across a wide range of concentrations and temperatures. Developed specifically for this duty.

    When you actually need a nickel alloy

    Nickel alloys cost significantly more than stainless or duplex steel, so we do not recommend them unless the service condition genuinely requires it. These are the cases where a nickel alloy is the right call, not an oversell:

    Hydrochloric acid at any concentration
    — Hastelloy B2 in reducing conditions, Hastelloy C276 or C22 if oxidising contaminants are present.
    Wet chlorine gas, hypochlorite bleach, or mixed oxidising acids
    — Hastelloy C276 or C22.
    Caustic soda service above 100°C
    — Nickel 200 below 315°C, Nickel 201 above it.
    Sustained service above 600°C with creep-rupture demands
    — Incoloy 800H or 800HT.
    Sour service under NACE MR0175 where duplex is not rated for the H₂S partial pressure
    — Incoloy 825 or Inconel 625.
    Seawater and marine hardware with galvanic or crevice concerns
    — Monel 400 or Inconel 625.
    If your condition is not on this list — general plant service, moderate chlorides, temperatures under 300°C — a 316L stainless or duplex 2205 pipe will likely perform the same job at a fraction of the cost.

    Tell us the fluid, concentration and temperature and we will recommend the most economical grade that actually holds up, even if that means quoting stainless instead of nickel.

    Sizes and wall thicknesses

    Wall thicknesses follow the same geometric standard (ASME B36.10M) regardless of material — a 6″ SCH 40 pipe has the same outside diameter and wall thickness whether it is carbon steel or Inconel 625. What changes is the weight, because nickel alloy densities vary more than stainless grades do.

    NPS OD (mm) SCH 10S SCH 40 SCH 80
    1/2″ 21.3 2.11 2.77 3.73
    1″ 33.4 2.77 3.38 4.55
    2″ 60.3 2.77 3.91 5.54
    3″ 88.9 3.05 5.49 7.62
    4″ 114.3 3.05 6.02 8.56
    6″ 168.3 3.40 7.11 10.97
    8″ 219.1 3.76 8.18 12.70

    All wall thicknesses in millimetres.

    Frequently asked questions

    Which nickel alloy should I use for hydrochloric acid?

    For pure hydrochloric acid in reducing conditions, Hastelloy B2 is the standard choice at any concentration. If oxidising contaminants like ferric or cupric ions are present in the same stream, switch to Hastelloy C276 or C22 — B2 has almost no chromium and will corrode rapidly if the environment turns oxidising.

    What is the difference between Nickel 200 and Nickel 201?

    Both are more than 99% pure nickel. The difference is carbon content: Nickel 200 allows up to 0.15% carbon, Nickel 201 is held to 0.02% maximum. Above 315°C, the higher carbon in Nickel 200 can precipitate as graphite at the grain boundaries and embrittle the material. Nickel 201 is the correct choice for any sustained service above that temperature.

    Should I specify seamless or welded nickel alloy pipe?

    Seamless is the default for pressure service, cyclic loading and sour service, and is readily available up to about 8 inch NB. Above that, welded (EFW) pipe to the matching ASTM spec is more commonly sourced and carries the same design allowances under ASME B31.3 when properly certified.

    What is nickel alloy pipe price based on?

    Nickel alloy pricing tracks the LME nickel price plus the individual alloying elements — molybdenum and chromium for Hastelloy grades, copper for Monel. It moves more than stainless steel pricing does. Send your grade, size and quantity and we will quote against current stock and mill pricing.

    What is your minimum order quantity?

    Yes. Every consignment ships with an EN 10204 3.1 mill test certificate showing heat number, chemical analysis and mechanical test results. Type 3.2 third-party certification is available on request.
