Characteristics

1. Easy processing

2. High tensile strength, fatigue strength, creep strength and fracture strength at 700℃

3. High oxidation resistance at 1000℃

4. Stable chemical properties at low temperature

5. Good welding performance


Metallographic structure

GH4169 alloy is an austenitic structure. The γ" phase generated after precipitation hardening gives it excellent mechanical properties. The δ phase generated at the grain boundary during heat treatment gives it the best plasticity.


Corrosion resistance

Inconel718 alloy has excellent resistance to stress corrosion cracking and pitting in both high and low temperature environments. Inconel718 alloy is particularly resistant to oxidation at high temperatures.


Application fields

Due to its high temperature strength, excellent corrosion resistance and easy processing at 700℃, Inconel718 alloy can be widely used in various high-demand occasions.

1. Steam turbine

2. Liquid fuel rocket

3. Cryogenic engineering

4. Acidic environment

5. Nuclear engineering
