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 than Inconel X-750 and better mechanical properties at lower temperatures than Nimonic 90 and Inconel X-750. Inconel 718 has exceptional weldability compared to the Nickel-base super alloys hardened by Aluminium and Titanium.
Diameter: 0.1 - 40mm
Shape: round, square, flat, special shaped
Inconel 718 offers the following key features:
Good creep rupture strength at high temperatures
