Champak Steel is a well-established manufacturer of Alloy Steel F91 Flanges. These flanges boast durability, anti-corrosive properties, high tensile strength, and resistance to oxidation, corrosion, stress corrosion cracking, and crevice corrosion. They are known for their good dimensional accuracy, making them suitable for various applications.
Alloy Steel F91 Flanges are crafted using a combination of high-quality metals such as Manganese, Molybdenum, Chromium, and Nickel, which impart excellent features. These flanges are ideal for use in high-pressure and extreme-temperature environments. Our manufactured products offer sturdiness, longevity, and resistance to corrosion, making them highly reliable for industrial use.
These flanges find applications in various industries, including nuclear power plants, valve and pump manufacturing, and hydrocarbon processing pipelines. They are also utilized in commercial kitchens and food processing plants due to their easy sterilization and maintenance properties.
Alloy Steel F91 Flanges are made of chromium molybdenum steel alloy, ensuring high rupture resistance while remaining lightweight. They exhibit resistance to sulfide corrosion cracking and hydrogen attacks, along with excellent ductility and durability.
In addition to their inherent characteristics, these flanges are easy to weld. We conduct a series of tests on our products to ensure high-quality standards, including eddy current testing, hydrostatic testing, chemical analysis, mechanical tests, and third-party inspections.
