Inconel 800H flanges
The Inconel 800H Flanges are crafted with incoloy 800 alloy family. Substantial nickel content in the base alloy attributes for the flanges’ outstanding resistance against corrosion, oxidation, carburization, sulfidation, among other harsh chemical conditions, while carefully controlled levels of titanium, carbon,and aluminum boost performance under intense heat conditions. Inconel 800H Flanges have proven efficient even when temperatures exceeds 1200° F, making them adaptable connection components with various types available such as forged flanges, plate flanges, orifice plates, and lap joint versions. Inconel 800H flanges are widely applied in offshore oil rigs, chemical plants, aerospace, marine environment, pipeline construction, etc.
SASA FLANGE offers a full range of ASTM B408 Inconel 800H flanges, including weld neck, slip-on, blind, socket weld, lap joint, and threaded types, available in ANSI/ASME, DIN, JIS standards, and we insist on reliable quality, full material traceability, and competitive pricing to meet the demanding needs of global clients.
