1.Introduction

Inconel 718 bar precipitation sclerosis type of molybdenum alloy containing niobium, nichrome, under

650 ℃ has high strength, good toughness and has good corrosion resistance in high and low temperature

 environment.The supply state can be solid solution treatment or precipitation hardening state.

2.Chemical composition

3. Heat conductivity

4.Chemical property

5.character

•  Ending machinability

•  Low at 700 ℃ has high tensile strength, fatigue strength, creep strength and fracture strength

•  Low at 1000 ℃ has the high oxidation

•  Both ends have stable chemical properties at low temperature

•  Ending with good welding performance

  6.Physical property

  Density:ρ=8.24g/cm3

  Melting temperature range:1260~1320℃ 

Inconel 718 applications:

because at 700 ℃ high temperature strength and excellent corrosion resistance,

easy workability, can be widely used in all kinds of high demand.

•  steam turbine.

•  liquid fuel rocket.

•  low temperature engineering.

•  acidic environment.

•  nuclear engineering.
