Nandini Steel is a well-known Inconel Flanges manufacturer in India providing high-quality flanges to challenging industrial conditions. Inconel Flanges are made of high strength nickel-chromium-based superalloys that are resistant to corrosion. As an Inconel Flanges manufacturer, we use the precision forging and machining processes that ensure greater mechanical strength and oxidation resistance. We produce Inconel Flanges in sizes ranging from 1/2″NB to 60″NB to comply with international quality requirements.

Trusted Inconel Flanges Manufacturer in Mumbai – Premium Grade 600, 625, 718 Flanges for High-Temperature & Corrosive Environments at Competitive Prices

Key Features of Inconel Flanges

High-Temperature Resistance: Inconel flanges maintain strength and stability in extreme heat which makes them ideal for high-temperature applications.
Corrosion Resistance: Excellent protection against oxidation, acid attacks and seawater corrosion especially in harsh environments.
Superior Strength: High tensile strength and durability under stress which makes them suitable for critical industrial use.
Versatile Grade Options: Available in popular grades like ASTM B564 UNS N06600, Inconel 601 Class 300 Flange and Inconel 625 grade 2 slip on flange.
Precision Engineering: Manufactured with accurate dimensions and fine surface finish for hassle-free fitting and performance.
Standard Compliance: Conforms to international standards such as ANSI, ASME, BS, DIN, EN for global compatibility.
Long Service Life: Minimal maintenance and high resistance to wear ensure long-term performance and cost efficiency.

Applications of Inconel Flanges

Inconel Flanges are utilized in sectors requiring high strength, heat and corrosion resistance. These flanges are used in chemical processing, power generation, marine engineering, oil & gas and aerospace sectors. Inconel Flanges are also used in high-temperature piping systems, heat exchangers, pressure vessels, reactors and exhaust systems that involve exposure to extreme environments and aggressive media. The strength and reliability of Inconel Flanges makes them suitable for demanding applications.

Comparison: Inconel 600 vs Inconel 625 Flanges

Inconel 600 forged flange is suitable for application with moderate corrosion resistance and great oxidation resistance at elevated temperatures. Inconel 600 blind flange performs well under heat and stress in work environments such as thermal and furnace equipment. In contrast, Alloy 625 weld neck flange has an increased ability to resist pitting, crevice corrosion and fatigue. Molybdenum and niobium produce superior strength and versatility allowing Alloy 625 to be utilized in marine, nuclear and chemical processing applications.

Packaging, Testing & Delivery

All of our Inconel Flanges are subjected to quality control testing including hydro static, PMI and dimensional tests. Each flange is packed safely in either a wooden crate or is palletized to safely transport. We are ISO 9001:2015 certified, which means compliance to global standards such as ANSI, ASME, BS, DIN and EN for quality assurance. Third party inspection and mill test reports are available upon request.
