Located in Jakarta, Indonesia, Ismail Flanges is a top producer and supplier of Hastelloy C76 Flanges, which are made to withstand severe corrosion in demanding industrial settings. The nickel-molybdenum alloy Hastelloy C76 is renowned for its exceptional resistance to potent oxidising and reducing agents, such as strong acids and corrosion caused by chloride. Our flanges are designed for high-performance applications in vital systems like pollution control units, offshore installations, and chemical processing facilities. Our Hastelloy C76 flanges are trusted for their exceptional mechanical stability, precision, and durability under harsh service conditions. They are available in a variety of types and pressure ratings and meet international standards.
Nickel (above 55%) and molybdenum (14–17%) make up the majority of Hastelloy C76 Flanges, with trace amounts of iron, cobalt, and carbon. This alloy exhibits remarkable resistance to pitting, stress corrosion cracking, and hydrochloric, sulphuric, and nitric acids. Mechanically, Hastelloy C76 has a yield strength of roughly 275–345 MPa and a tensile strength of roughly 690–760 MPa. It also provides good ductility and high elongation. For an extended service life, these characteristics guarantee that the flanges function well in corrosive, high-pressure, and high-temperature environments.

Ismail Flanges, a leading supplier in Indonesia, Jakarta, offers an extensive selection of Hastelloy C276 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 C76 Flanges are utilised in harsh and highly corrosive chemical processing settings. They are perfect for scrubbers, condensers, heat exchangers, reactors, and pressure vessels in the pulp and paper, wastewater treatment, petrochemical, and pharmaceutical industries. These flanges are used in marine and offshore engineering because of their resilience to chloride-rich environments and their consistent performance in systems that handle strong acids, particularly sulphuric and hydrochloric acid. They are appropriate for applications involving thermal cycling and fluctuating pressure because of their exceptional resistance to heat and chemicals. For systems that require a lot of maintenance and safety, Hastelloy C76 flanges are preferred.
