| High Light | Hastelloy C276 slip-on flange ，Nickel alloy SO RF flange ，ASTM B564 forged flange | ||
ASTM B564 N10276 SO RF Flange is a high-end corrosion-resistant nickel-based superalloy forged flange, strictly manufactured in accordance with ASTM B564 (material standard) and ASME B16.5 (dimensional standard). N10276 (commonly known as Hastelloy C276) is a premium nickel-chromium-molybdenum-tungsten alloy, renowned for its exceptional corrosion resistance to almost all strong corrosive media (including sulfuric acid, hydrochloric acid, phosphoric acid, chloride solutions, and seawater), as well as good high-temperature strength and weldability. As a Slip-On (SO) flange with Raised Face (RF), it features convenient installation, reliable sealing, and strong adaptability, specially designed for harsh corrosive and high-temperature industrial piping systems, widely applied in petrochemical, marine engineering, chemical processing, and other critical fields.
