Hastelloy flanges follow ASTM B564 standard specifications for nickel alloy forgings. They cover pressure classes from 150# to 2500# and sizes from 1/2' to 48' (and up to 60' in select series). Common grades include C276, C22, and B2 designed for extreme corrosion resistance. [1, 2, 3, 4] Key Specifications & Standards • Material Standards: ASTM B564 / ASME SB564 (forgings), ASTM B574 • Dimensions & Tolerances: ANSI/ASME B16.5, B16.47 (Series A & B), B16.48, MSS SP44, DIN, EN-1092, BS 4504 • Size Range: 1/2″ (15NB) to 48″ (1200NB) • Pressure Ratings: Class 150#, 300#, 600#, 900#, 1500#, 2500#; PN6 to PN64 [1, 2, 4, 5, 6] Common Grades and UNS Numbers • Hastelloy C276: UNS N10276 (W.Nr. 2.4819) – Most common, excellent multi-acid resistance • Hastelloy C22: UNS N06022 (W.Nr. 2.4602) – Superior resistance to localized corrosion and oxidizing media • Hastelloy B2: UNS N10665 (W.Nr. 2.4617) – Optimized for reducing environments (hydrochloric acid) • Hastelloy X / C2000: Additional high-temperature or specialized chemical grades [2, 4, 7, 8, 9] Flange Types and Facings • Types: Weld Neck (WN), Slip-On (SO), Blind (BL), Socket Weld (SW), Threaded, Lap Joint, and Ring Type Joint (RTJ) • Face Types: Raised Face (RF), Flat Face (FF), Ring Type Joint (RTJ) [2, 3, 9] If you need help specifying a part, tell me:The grade you require (e.g., C276 or C22)The pressure class and sizeThe flange type (Weld Neck, Blind, Slip-On, etc.)I can provide more detailed mechanical properties or dimensional tolerances for your exact requirement.
