Harsh Flanges is a leading manufacturer and supplier of Hastelloy Flanges, proudly based in Mumbai, India. They’re recognized for their commitment to delivering top-notch quality and performance across a variety of demanding industries. With a focus on corrosion-resistant alloys, Harsh Flanges specializes in precision-engineered Hastelloy flanges that adhere to global standards, making them perfect for critical applications in sectors like chemical processing, marine, and power generation. Thanks to their advanced manufacturing technology and dedication to customer satisfaction, the company guarantees reliable, durable, and high-strength flanges. Harsh Flanges truly shines with its technical know-how, quick delivery, and ability to provide custom solutions tailored to unique operational needs.
Hastelloy flanges are mainly made up of nickel (60–70%), along with notable amounts of molybdenum (up to 28%), chromium, iron, cobalt, and trace elements. This distinctive blend gives them remarkable resistance to corrosion, particularly in acidic and oxidizing environments. On the mechanical side, Hastelloy flanges boast high tensile strength (up to 790 MPa), impressive yield strength, and good ductility. They perform reliably even under extreme temperatures and high-pressure situations, resisting pitting and crevice corrosion, and can be welded without losing their mechanical integrity. These features make Hastelloy flanges an excellent choice for highly corrosive and high-stress applications.
