ASTM B564 Inconel 625 WNRF Flange
Product Introduction
Inconel 625 Welding Neck Raised Face Flanges for Corrosive Process Piping
ASTM B564 Inconel 625 WNRF Flanges are forged from UNS N06625 nickel-chromium-molybdenum-niobium alloy and machined with a welding neck and raised face configuration.
The alloy is selected for piping systems where resistance to chloride-containing environments, localized corrosion and elevated-temperature exposure is important. The long tapered hub of the welding neck flange provides a gradual transition from the pipe to the flange body, making this configuration suitable for pressure and cyclic-service piping.
Flange dimensions, bolt-hole patterns and pressure classes can be manufactured according to ASME B16.5, ASME B16.47 or other applicable dimensional standards, while the material forging specification follows ASTM B564.

Product Features
UNS N06625 provides a combination of corrosion resistance and mechanical strength for demanding process environments.
The tapered hub creates a gradual transition between the pipe wall and flange, making the WN configuration suitable for pressure and cyclic loading.
The RF configuration provides a defined gasket seating area for bolted piping connections.
Bolt holes, bore, flange thickness and facing dimensions can be CNC machined according to the applicable dimensional standard.
Heat-number traceability and material documentation can be provided for project-controlled applications.
