Description
ASTM B462 C276 WN RF Flange, Hastelloy C276 Weld Neck Raised Face Forged Flange
Brief Introduction

ASTM B462 C276 WN RF Flange is a high-end corrosion-resistant nickel-based superalloy forged flange, strictly manufactured in accordance with ASTM B462 (material standard for Hastelloy C276 forgings) and ASME B16.5 (dimensional standard). C276 (commonly known as Hastelloy C276) is a premium nickel-chromium-molybdenum-tungsten alloy, famous for its exceptional resistance to almost all strong corrosive media (including sulfuric acid, hydrochloric acid, phosphoric acid, chloride solutions, and seawater). As a Weld Neck (WN) flange with Raised Face (RF), it features high structural strength, reliable sealing performance, and strong connection stability, specially designed for high-temperature, high-pressure, and harsh corrosive industrial piping systems, widely applied in petrochemical, marine engineering, chemical processing, and other critical fields.
