Inconel 718 2.4668 steel pipe fabrication good resistance to oxidation
One of the distinguishing features of Inconel 718¡¯s composition is the addition of niobium to permit age hardening which allows annealing and welding without spontaneous hardening during heating and cooling.
The addition of niobium acts with the molybdenum to stiffen the alloy¡¯s matrix and provide high strength without a strengthening heat treatment. Uses for Inconel 718 tend to be in the field of gas turbine components and cryogenic storage tanks. Jet engines, pump bodies and parts, rocket motors and thrust reversers, nuclear fuel element spacers, hot extrusion tooling. Other popular uses are high strength bolting, and down hole shafting.
