Inconel® threaded flanges, like Inconel 600, 601, 625, 686, 718 & 725 threaded flanges, are a family of nickel-chromium-molybdenum alloys used for their high strength at elevated temperatures and good corrosion resistance. Because of its high thermal stability, Inconel threaded flanges can be used in service temperatures ranging from cryogenic to 2200°F (982°C). The high alloy content of Inconel threaded flanges enable it to withstand a wide variety of severe corrosive environments. In mild environments, such as the atmosphere, sea water, neutral salts, and alkaline media, there is almost no attack to Inconel threaded flanges. In more severe corrosive environments the combination of nickel and chromium provides resistance to oxidizing chemicals, whereas the high nickel and molybdenum contents supply resistance to nonoxidizing environments.
Because Inconel threaded flanges offer a good balance of corrosion resistance, temperature stability, toughness and strength they are often a material of choice for chemical processing, aerospace, marine, electronics and oil & gas.
The most common grades of Inconel nickel alloy flanges are Inconel 625 and Inconel 718. Gain more insight on these two grades by accessing our Inconel 625 and Inconel 718 overviews or by contacting our engineering experts.

Frequently Asked Questions
Q: What is a inconel threaded flanges used for?
A: These flanges connect threaded pipe or equipment nozzles where welding is undesirable or difficult, especially in corrosive, high-temperature, or cryogenic service. Typical applications include chemical processing, offshore systems, heat exchangers, scrubbers, and sour-gas lines. Inconel grades provide oxidation, carburization, and chloride resistance, with service capability from cryogenic conditions up to 2200°F (982°C), depending on alloy selection such as 600, 601, 625, or 718.
Q: What materials are available for inconel threaded flanges?
A: Available alloys include Inconel 600, 601, 625, 686, 718, 725, and X750. These are nickel-chromium-molybdenum based materials selected for different service conditions. Grade 600 offers oxidation and carburization resistance to 2000°F, 601 to 2200°F, 625 resists oxidation to 1800°F, and 718 provides strong creep-rupture performance to 1300°F. SASA FLANGE supplies material with EN 10204 3.1 MTC for traceability and compliance.
Q: What pressure ratings does a inconel threaded flanges support?
A: Pressure rating depends on flange dimensions, thread form, alloy grade, temperature, and the governing ASME specification rather than alloy alone. Threaded flanges are typically produced to ASME pressure classes such as 150, 300, 600, 900, 1500, and 2500 when required by design. For Inconel service, derating at elevated temperature is critical, especially above 1000°F. SASA FLANGE can manufacture according to your specified class, facing, and operating conditions.
