Incoloy alloy flange is an industrial pipe fitting made of nickel iron chromium alloy, which has excellent high temperature resistance and corrosion resistance. It is widely used in harsh industrial environments such as high temperature, high pressure, and strong corrosion. Here is a detailed introduction about it:

Common types and chemical composition

Incoloy 800 series: including Incoloy 800, 800H, and 800HT. Its main chemical components include nickel content of 30.0% -35.0%, chromium content of 19.0% -23.0%, iron content of not less than 39.5%, and trace elements such as titanium and aluminum. Among them, 800H improves high-temperature strength by increasing carbon content, while 800HT further adjusts aluminum and titanium content to enhance high-temperature performance.

Incoloy A-286: Its chemical composition is based on weight percentage, with nickel at 25% -30%, chromium at 13% -16%, iron as the balance, molybdenum at 1.5% -2.5%, titanium at 1.0% -2.0%, etc. These components endow it with excellent high-temperature oxidation resistance, corrosion resistance, and mechanical properties.

Performance Characteristics

High temperature resistance: Incoloy 800 series flanges can maintain oxidation and carburizing resistance in environments up to 1100 ° C. Incoloy A-286 can work stably in the range of 700 ° C-1000 ° C and is suitable for industrial equipment in high-temperature environments.

Corrosion resistance: Koloi alloy has good resistance to various corrosive media, such as Incoloy A-286, which has good corrosion resistance to chlorides, sulfides, strong acids such as nitric acid and sulfuric acid, and strong resistance to stress corrosion cracking.

Mechanical strength: It has high tensile strength and yield strength. The tensile strength of Incoloy 800 flange is usually as high as 520MPa, and the yield strength is 205MPa. It can still maintain good strength at high temperatures and has excellent creep resistance and fracture resistance.

Processing and weldability: Due to the excellent processing performance of Chloe alloy flanges, they can be processed and formed through forging, rolling and other processes, and have good weldability. Welding methods such as MIG and TIG can be used for welding.

Application field

Chemical and petrochemical industries: Due to its ability to withstand oxidation, carburizing, and sulfurization at high temperatures, Koloi alloy flanges are commonly used in key components such as heat exchangers and process pipelines.

Power generation industry: In high-temperature equipment such as steam generators in power plants, Chloe alloy flanges ensure reliable operation of the equipment due to their durability and resistance to thermal fatigue.

Aerospace and automotive industries: used for manufacturing components that need to withstand extreme conditions, their high temperature strength and thermal expansion resistance help improve equipment safety and efficiency.

production standard

Due to the fact that the production of Chloe alloy flanges usually follows international standards such as ASME, DIN, EN, JIS, etc., their size specifications range widely from 1/2 "to 48" (DN10-DN4000), and pressure ratings cover PN6-PN100, etc.
