Premium-grade Hastelloy Blind Flanges made for demanding and corrosive service environments are available from Harsh Flanges, a respectable manufacturer and supplier with headquarters in Mumbai, India. In high-stress industrial applications, these flanges are used to seal the ends of piping systems, offering a safe and resilient closure against corrosion. Our blind flanges are made with premium Hastelloy alloys like C22 and C276, which satisfy international requirements for durability, strength, and accuracy. Harsh Flanges provides specialised flange solutions made to withstand harsh fluids and harsh operating conditions to a wide range of industries, including chemical processing, pharmaceuticals, marine, and pollution control.
The main component of Hastelloy Blind Flanges is nickel (up to 60%), with notable additions of iron, cobalt, molybdenum (up to 17%), chromium (up to 22%), and trace elements like tungsten. These components offer outstanding defence against oxidizing/reducing conditions, pitting, and crevice corrosion. Tensile strength of 690–785 MPa, yield strength of 283–355 MPa, and elongation of approximately 40% are typical mechanical characteristics. Hastelloy blind flanges are perfect for applications requiring high mechanical strength and superior corrosion resistance because they maintain their mechanical integrity in acidic and high-temperature environments.

Harsh Flanges, a leading supplier in Mumbai, India, offers an extensive selection of Hastelloy Blind Flanges, including weld neck flanges, slip-on flanges, blind flanges, threaded flanges, and lap joint flanges. Designed for diverse industrial applications, our high-quality inventory and commitment to exceptional service make us a trusted choice for flange products in the region.
Hastelloy Blind Flanges are extensively utilised in waste treatment facilities, pulp and paper manufacturing, pharmaceutical manufacturing, nuclear and marine applications, and chemical processing plants. They are perfect for sealing pipelines carrying acids, seawater, and aggressive chemicals because of their resistance to extremely corrosive fluids. When system closure without fluid flow is necessary, these flanges are frequently placed at the ends of reactors, piping systems, and pressure vessels. They are a dependable option for demanding applications involving high pressure, extreme temperatures, and volatile substances because of their exceptional weldability and resistance to stress corrosion cracking caused by chloride.
