Amigo Impex is an Inconel 600 pipe manufacturer and supplier based in Mumbai, India, and has stocked and exported the grade for over a decade. The seamless product is supplied against ASTM B167 / ASME SB-167. Welded pipe follows ASTM B517; welded tube follows ASTM B516.
Inconel 600 tubes and pipes are a nickel-chromium-iron alloy, designated as UNS N06600, built on a 72.0% minimum nickel base with 14.0-17.0% chromium. The chemistry holds a protective oxide film at surface temperatures up to 1093°C (2000°F) and resists chloride-ion stress-corrosion cracking in hot process streams. Annealed material meets 515 to 550 MPa minimum tensile strength depending on the working route and diameter, with yield and elongation minimums varying in the same way, as set out in the mechanical properties table below. The pipe bends, expands into tube sheets and welds without cracking. Drawings issued to 2.4816, NCF 600 or NA 14 are supplied against the same alloy. Pipe spans 1/8″ to 8″ NB in SCH 40 and SCH 80; tube runs from 0.125″ to 8″ OD in 3 m and 6 m lengths, cut to size on request.
Amigo Impex keeps 60 to 70 tonnes of Alloy 600 stock in Mumbai and supplies against urgent order books, priced per kilogram. We cut, machine, thread, fabricate, test, and pack every line item in-house. Every order leaves our warehouse with a mill test certificate. As trusted Inconel 600 pipe suppliers, we provide nuclear steam generators, petrochemical reformers, chlorine processing plants, and furnace equipment with fast dispatch times.
The table below defines Alloy 600 pipes and tubes as an orderable product, covering standards, sizes and schedules, lengths, end preparation, finish and construction route. Every enquiry is checked against it before we quote.

A 72.0% minimum nickel floor gives Alloy 600 pipes and tubes their resistance to chloride stress cracking; chromium at 14.0–17.0% forms the oxide barrier. The B167 / SB-167 limits below are verified on each heat's mill certificate.
| Element | Composition (%) |
|---|---|
| Nickel (Ni) | 72.0 min |
| Chromium (Cr) | 14.0–17.0 |
| Iron (Fe) | 6.00–10.00 |
| Carbon (C) | 0.15 max |
| Manganese (Mn) | 1.00 max |
| Silicon (Si) | 0.50 max |
| Copper (Cu) | 0.50 max |
| Sulphur (S) | 0.015 max |
ASTM B167 / ASME SB-167 sets different minimums depending on the working route and the outside diameter. All four cases are listed below; the applicable row is confirmed on the mill test certificate for each heat.
| Condition and Size | Tensile Strength (min) | Yield Strength 0.2% offset (min) | Elongation (min) |
|---|---|---|---|
| Hot-worked or hot-worked annealed, 5″ (127 mm) OD and under | 550 MPa (80 ksi) | 205 MPa (30 ksi) | 35% |
| Hot-worked or hot-worked annealed, over 5″ (127 mm) OD | 515 MPa (75 ksi) | 170 MPa (25 ksi) | 35% |
| Cold-worked annealed, 5″ (127 mm) OD and under | 550 MPa (80 ksi) | 240 MPa (35 ksi) | 30% |
| Cold-worked annealed, over 5″ (127 mm) OD | 550 MPa (80 ksi) | 205 MPa (30 ksi) | 35% |

We supply five constructions of Inconel 600 pipe and tube across the seamless and welded routes, with square and rectangular sections produced against order:
Pipes are issued in strapped bundles with end protection, while smaller tubes and cut lengths go into wooden boxes or crates lined against moisture. Amigo Impex dispatches pan-India from Mumbai and exports Inconel 600 pipes and tubes to the USA, the Gulf, Europe and Asia with export documentation. Made-to-order material carries a lead time of around 30 days; urgent ready-stock consignments leave within 1 to 2 days.
We test each heat of UNS N06600 pipe and tube for tensile properties, chemical composition and hardness, and run PMI checks in-house before packing. A mill test certificate travels with every order, and third-party inspection is supported on request. Amigo Impex operates under AS 9120B, PED, ISO 9001:2015 and ISO 45001:2018 certification.
Inconel 600 pipes and tubes are priced at ₹2,500 to ₹5,000 per kg for domestic supply and at approximately US $27 to $55 per kg for export orders. OD, wall thickness, length, construction route, finish and quantity fix the final figure. Nickel rates move with the metal market, so every enquiry receives a dated quotation rather than a standing price list.

ASTM B167 / ASME SB-167 is the standard for seamless Inconel 600 pipes and tubes. Welded pipe is supplied to ASTM B517, welded tube to ASTM B516 and seamless heat exchanger tube to ASTM B163.
Inconel 600 pipe price ranges between ₹2,500 and ₹5,000 per kg (approximately US $27 to $55 per kg) for domestic supply. The confirmed rate depends on OD, wall thickness, construction and quantity, so request a dated quotation.
Inconel 600 seamless pipe is produced without a weld seam under ASTM B167 and suits code-critical lines. Welded pipe to ASTM B517 is made from flat-rolled alloy by an automatic welding process with no filler metal added, then cold-worked and annealed, and costs less in larger diameters.
1093°C (2000°F) is the maximum service temperature for Inconel 600 pipes and tubes in oxidising atmospheres, and toughness doesn't drop at cryogenic temperatures.
Yes. At moderate temperatures, the chromium content gives Alloy 600 resistance to sulphur compounds. At elevated temperatures, it becomes subject to sulphidation, so discuss the operating temperature with us before specifying it for high-temperature sulphidising duty.
Yes, Alloy 600 has excellent resistance to high-purity water but is subject to stress-corrosion cracking in high-temperature, high-strength caustic alkalies. Share the concentration and operating temperature with us before specifying it for caustic duty.
