Not to be confused with Inconel, Incoloy threaded flanges are made of a nickel alloy which contains iron and a lower content of nickel. Incoloy is essentially a more economical option to Inconel, yet with more restricted corrosion resistance and temperature limits. Typically, Incoloy is an ideal material for long-term exposure in high temperature environments due to its oxidation, carburization and creep resistance. Incoloy is widely used for its resistance to seawater, brine, sour gas and high chloride environments at elevated temperatures, which make it a popular choice in the oil and gas and power industries.
The most commonly used grades of Incoloy flanges are Incoloy 800, 800H, 800HT;Incoloy 825; and Incoloy 925. For more indepth information on these specific grades, visit our specific web pages or contact one of our engineering experts:

Incoloy Threaded Flanges Serving Demanding Energy and Process Sectors
SASA FLANGE incoloy threaded flanges are widely used in oil and gas service, especially where resistance to seawater, brine, sour gas, and high chloride environments at elevated temperatures is needed.
In power generation, they suit high temperature steam systems because the alloy maintains stable structure and strength during prolonged heat exposure.
In petrochemical and pilot processing lines, threaded construction is valuable when welding is dangerous or when frequent system reconfiguration is necessary.

Frequently Asked Questions
Q: What is a incoloy threaded flanges used for?
A: These flanges connect threaded pipe to valves, fittings, and equipment without welding, using a tapered female thread for leak-tight assembly. They are selected for corrosive and high-temperature service where Incoloy alloys outperform standard stainless steels. Typical applications include heat exchangers, chemical processing, offshore systems, sour service per NACE MR0175, and furnace or petrochemical piping using grades such as 800, 800H, 800HT, 825, and 925.
Q: What materials are available for incoloy threaded flanges?
A: Available materials include Incoloy 800, 800H, and 800HT for oxidation resistance and elevated-temperature strength; Incoloy 825 with molybdenum and copper for stronger resistance to sulfuric and phosphoric acids; and Incoloy 925, a precipitation-hardened nickel-iron-chromium alloy with high strength and corrosion resistance. Material selection depends on chloride exposure, sour service, operating temperature, and mechanical load requirements. MTC is supplied to EN 10204 3.1.
Q: What pressure ratings does a incoloy threaded flanges support?
A: Pressure class is not fixed in the provided specification and is supplied according to project requirement. Threaded designs are commonly produced to standard flange classes based on size, alloy grade, thread form, and service temperature. For Incoloy 800/825/925 applications, actual rating must be confirmed against ASME dimensions, wall thickness, and operating conditions. SASA FLANGE can match the required pressure class for custom orders after technical review.
Q: What standards does a incoloy threaded flanges comply with?
A: These flanges can be manufactured and certified to ASTM B408, ASME SB408, ASTM B564, ASME SB564, ASTM B425, ASME SB425, ASTM B637, BS 3076NA16, DIN 17752, DIN 17753, DIN 17754, VdTÜV 432, ISO 9723, ISO 9724, ISO 9725, ASME Code Case N-572, and NACE MR0175 where applicable. Material test certificates are provided per EN 10204 3.1 for full traceability.
Q: What is the lead time for custom incoloy threaded flanges orders?
A: Custom orders typically require 15-30 days, depending on alloy grade, size, machining scope, and certification requirements. In-stock items can ship in 3-7 days. For custom threaded flanges in Incoloy 800H, 825, or 925, lead time may vary with raw material availability and thread specification.
