Hastelloy C276 Flanges
Hastelloy C276 flanges are manufactured using the hastelloy C276 alloy composed of nickel, molybdenum, and chromium, along with inclusion of 50.99% nickel, 14.5% chromium and 15% molybdenum; it also contains carbon, manganese, silicon, sulfur, cobalt iron phosphorus among other components.
These flanges boast a high melting temperature of approximately 1370 °C while providing impressive tensile strength at least equal to or greater than 790 MPa minimum yield strength exceeding 355 MPA . Their outstanding corrosion resistance makes them suitable for both oxidizing & reducing environments all whilst maintaining structural integrity even under intense heat exposure, thus widely applied in industries requiring superior anti-corrosive properties like offshore oil drilling, power generation, petrochemicals gas processing, etc.
At SASA FLANGE, we offer wide range of Hastelloy C276 Flanges including slip-on flanges, weld necks, socket weld options, blind flanges configurations, lap joint types, threaded types, long weld neck options, available in ANSI/ASME, DIN, JIS standards. We ensure reliable quality, full material traceability, and competitive pricing to meet the demanding needs of global clients.
