Amigo Impex is an Inconel 600 flanges manufacturer, supplier, stockist and exporter operating from Mumbai, India. Our company has worked with nickel alloys since 2013 and forges UNS N06600 flanges to ASTM B564 and its ASME counterpart SB-564. Cutting, machining, threading, fabrication, testing and packing all run in-house, which keeps facing tolerances and delivery dates under direct control.
Inconel 600 is a nickel-chromium-iron alloy carrying 72.0% minimum nickel with 14.0 to 17.0% chromium. That balance resists chloride-ion stress corrosion cracking and holds a stable oxide film in hot service above 2000 °F. Note that this is the alloy's oxidation limit; the flange joint itself is governed by the ASME B16.5 pressure-temperature ratings for Material Group 3.5, which stop well below that figure. Annealed forgings meet a 550 MPa minimum tensile strength. Drawings marked W.Nr. 2.4816, NiCr15Fe or JIS NCF 600 name the same material as UNS N06600, so the order can be processed against the existing ASTM B564 certification without raising a new material grade. Ten forged constructions are produced. The range starts at weld neck and slip-on patterns and extends through reducing and spectacle blind specials. Sizes run 1/2" to 48" NB. Class 150 to 1500 is available 1/2" to 24" and Class 2500 from 1/2" to 12", both to ASME B16.5. From 26" to 48", ASME B16.47 Series A and B apply, where the highest class is 900.
Furnace builders, chemical processors and power stations account for most repeat orders. Around 60 to 70 tonnes of ready nickel alloy stock are in Mumbai for immediate processing. A material test certificate accompanies every consignment; pricing is confirmed per kilogram once type, size and class are fixed, and each flange traces back from final inspection to its mill heat.
Production of Inconel 600 flanges at Amigo Impex follows the parameters below, from governing standard and bore range through pressure classes, facings and certification paperwork. Orders are confirmed against these limits before forging.
ASTM B564 governs the forged UNS N06600 material itself, while nominal bore decides the dimensional code.

Ni-Cr-Fe alloy 600 flanges contain no molybdenum. Nickel at 72.0% minimum supplies the resistance to chloride stress corrosion cracking. Chromium at 14.0 to 17.0% sustains oxidation resistance at furnace temperatures.
| Element | Composition (%) |

Forged Inconel 600 flange material in the annealed condition must reach the ASTM B564 minima below. Certified tensile, yield and elongation results for every heat appear on the accompanying test certificate.
| Property | Minimum Value (Annealed) |
|---|---|
| Tensile Strength | 80 ksi (550 MPa) |
| Yield Strength (0.2% Offset) | 35 ksi (240 MPa) |
| Elongation in 2" | 30% |
European, Japanese, British, French, Chinese and Russian systems assign their own numbers to Alloy 600 flanges; each designation below maps to UNS N06600. A drawing raised against 2.4816 or NCF 600 doesn't call for requalification.
| Country / Standard | Designation |
|---|---|
| USA(UNS) | UNS N06600 |
| Europe (EN / W.Nr.) | 2.4816 / NiCr15Fe |
| United Kingdom (BS) | United Kingdom (BS) |
| Japan (JIS) | NCF 600 |
| France (AFNOR) | NC15Fe |
| China (GB) | NS3102 / GH3600 |
| Russia (GOST) | KhN78T (approximate equivalent, not a certified match) |
Ten forged Inconel 600 flange types serve the full run of joint positions; weld neck, slip-on, and blind patterns move fastest from ready stock.
Machined faces are wrapped piece by piece before Inconel 600 flanges go into wooden cases, crates or pallets for transit. Every flange carries its heat number, size, class and specification stamp, so traceability survives site storage. Dispatches from Mumbai reach all of India, while export consignments move to the USA, the Gulf, Europe and Asia with documentation prepared in-house. Ready-stock orders leave within 1 to 2 days; made-to-order forgings follow in around 30 days.
Every UNS N06600 flange order ships with the mill's EN 10204 3.1 certificate for the parent material, plus Amigo Impex's own test and inspection report for the forging and machining operations. Third-party inspection is supported where the purchase order names a witnessed release. Amigo Impex holds AS 9120B, PED, ISO 9001:2015 and ISO 45001:2018 certifications.
Inconel 600 flanges are priced at approximately ₹3,684–₹4,019 per kg in India and US$44–US$48 per kg internationally. Nickel-market movements, flange type, nominal bore, pressure class, facing, quantity, testing scope, and certification determine the final quotation, while volume enquiries may receive wholesale terms.
