N07718 Inconel 718 Nickel-Chromium Alloy Pipe

Product Description

N07718 Inconel 718  Nickel-Chromium Alloy Pipe  Introduction Inconel 718 is a Nickel-Chromium alloy being precipitation hardenable and having high creep-rupture strength at high temperatures to about 700°C (1290°F). It has higher strength thanInconel X-750 and better mechanical properties at lower temperatures than Nimonic 90 andInconel X-750.Chemical Composition of Inconel 718The compositional range for Inconel 718 is provided in the table below.
