Alloy 718 tubes Easy to process,with High tensile strength,fatigue strength,creep strength and fracture strength at 700℃.More,Alloy 718 tube with High oxidation resistance at 1000℃ ,also with Stable chemical composition at low temperature.

All 718 pipes also with Good welding performance,could be made nickel alloy pipe lines different parts with alloy 718 pipe fittings.

718 alloy tube has excellent Corrosion resistance resistance to stress corrosion cracking and pitting at both high and low temperatures. The oxidation resistance of 718 alloy is especially excellent at high temperature.

Metallographic structure 718 alloy has austenitic structure,and the Y phase formed after precipitation and hardening gives it excellent mechanical properties. The best ductility is achieved by the formation of △ phase at grain boundaries during heat treatment.Due to high temperature strength and excellent corrosion resistance at 700℃, easy to process, the 718 tubing can be widely used in a variety of demanding applications
