Alloy Steel F91 Flanges
Champak Steel is an established manufacturer, stockiest, supplier, and distributor of Alloy Steel F91 Flanges. Alloy steel F91 slip on flanges are durability and longevity, anti-corrosive, high tensile strength, oxidation/corrosion/stress corrosion cracking and crevice corrosion resistance. One important feature is good dimensional accuracy. Alloy Steel F91 weld neck Flanges with the combination of purest metals such as Manganese, Molybdenum, Chromium, and Nickel. Because of these metals, these flanges show an excellent feature such as it can generally use in high-pressure as well as high or low temperatures applications. Our manufactured products show some unique features and benefits to our customers. Such features are sturdiness, high tensile strength, anti-corrosive, corrosion/ oxidation/ stress corrosion cracking/ crevice corrosion resistance, good dimensional accuracy, durability, and longevity, and many more.
Alloy Steel F91 Welding Neck Flange have their applications in the various applications such as nuclear power plants valves and pump manufacturing, hydrocarbon processing pipelines and more. The energy consumption based on the production of these Alloy Steel F91 Slip On Flanges has decreased recently due to technological improvements and energy conservation measures.

This also influences its use in commercial kitchens and food processing plants, as our Alloy Steel F91 Threaded Flanges can be steam – cleaned and sterilized and does not need paint or other surface finishes. Alloy Steel F91 Flanges are made up of chromium molybdenum steel alloy and therefore have a high rupture resistance. They are also preferred due to their light weight because of the low carbon and high alloy nature. It is very much resistant to sulfide corrosion cracking, and can also withstand hydrogen attacks. F91 threaded flange is known to be extremely ductile, durable and tough.
Apart from these characteristics, these flanges are easy to weld. We perform a number of tests on our flanges to ensure high standard quality. The tests conducted are eddy current testing, hydrostatic testing or ultrasonic examination, NDT and also chemical and physical property inspection. Some of the other tests are chemical analysis, Rockwell hardness test, chemical test, mechanical test, intergranular corrosion test, positive material test, flattening test, flaring test, and third-party inspection and so on.
