UNS N10276 Hastelloy C276 Plate Flanges Manufacturer Stockist Exporter
We are manufacturers, stockist and exporters of UNS N10276 Hastelloy C276 Plate Flanges in Mumbai.
Synergy Engineering Solution is a prominent manufacturer, stockist, and exporter of UNS N10276 Hastelloy C276 Plate Flanges, catering to customers in Oman, Qatar, Saudi Arabia, UAE, Kuwait, Spain, Germany, the USA, Canada, and various regions across Africa and worldwide. Known for their commitment to quality and precision, the company provides flanges that meet international standards and offer unmatched reliability in aggressive industrial environments.
Hastelloy C276, designated as UNS N10276, is a nickel-molybdenum-chromium alloy with the addition of tungsten, designed for exceptional resistance to a wide range of chemical environments. C276 Plate Flanges are highly resistant to strong oxidizers, reducing agents, and localized corrosion such as pitting, crevice attack, and stress corrosion cracking. This makes them an ideal choice for industries like chemical processing, petrochemicals, pharmaceuticals, pollution control, and marine engineering.
Synergy Engineering Solution manufactures a wide variety of C276 plate flanges, including blind, slip-on, socket weld, threaded, and lap joint flanges, all produced with high precision and in compliance with ASTM B564 / ASME SB564 standards. These flanges are available in multiple sizes, pressure ratings, and finishes to meet diverse customer requirements across industries.
The alloy composition of Hastelloy C276—featuring approximately 57% nickel, 15–17% molybdenum, 14.5–16.5% chromium, 3–4.5% tungsten, and trace amounts of iron, cobalt, and manganese—provides excellent resistance against both oxidizing and reducing conditions. This unique balance allows UNS N10276 flanges to perform efficiently in harsh environments such as flue gas scrubbers, sour gas systems, and acid production plants.
Types Of Flanges manufacturer
Mechanically, Hastelloy C276 plate flanges offer tensile strength of around 690 MPa, yield strength of 283 MPa, elongation of 40–45%, and superior toughness across a wide temperature range. These properties ensure excellent durability and long-term performance in applications where high strength and corrosion resistance are critical.
Synergy Engineering Solution ensures every shipment of UNS N10276 Hastelloy C276 Plate Flanges is accompanied by Mill Test Certificates (MTC), third-party inspection reports, and complete export documentation. With a strong logistics and supply chain network, the company guarantees timely delivery worldwide, reinforcing its reputation as a trusted and reliable exporter of premium-grade Hastelloy C276 flanges.
