Hot – working in our Inconel 718 Blind Spectacle Flanges is carried out using a 2050 Degree F (1121 Degree C) maximum furnace temperature. These Inconel 718 Weld Neck Flanges is age harden able and may be welded in fully aged condition. Meanwhile, our Inconel 718 Blind Flanges are as well being offered in different sizes and shapes to our customers.

These Inconel 718 Socket Weld Flanges is also used in jet engines, pump bodies and parts, rocket motors and thrust reversers, nuclear fuel element spacers, hot extrusion tooling, etc. Our Inconel 718 Lap Joint Flanges represents about half of their world tonnage and is considered as a refractory super – alloy since it can be used permanently above 600 Degree C. The addition of niobium acts with the molybdenum to stiffen the matrix of these Inconel 718 Ring Type Joint Flanges and provide high strength without a strengthening heat treatment.
