Description
Monel 400 Flanges
Monel 400 Flanges are manufactured from a high-strength nickel-copper alloy (UNS N04400 / W.Nr. 2.4360) that provides excellent resistance to seawater, acids, and alkalis. Known for their durability and toughness, these flanges are widely used in marine engineering, chemical processing, oil & gas, and power generation. We supply a full range of ASTM B564 Monel 400 Flanges, including weld neck, slip-on, blind, socket weld, lap joint, and threaded types, available in ANSI/ASME, DIN, and JIS standards. At SASA FLANGE, we ensure reliable quality, full material traceability, and competitive pricing to meet the demanding needs of global clients.
