Inconel 718

Inconel 718 is a precipitation-hardenable, Nickel-Chromium alloy containing also significant amounts of Iron, Niobium and Molybdenum, also with fewer amounts of Aluminum and Titanium. It is widely used in gas turbines, rocket motors, space-craft, unclear reactors, pumps and tooling.

Inconel 718 characteristic as below.
1. Workability

2. High tensile strength, endurance strength, creep strength and rupture strength at 700°C.

3. High inoxidability at1000°C.
4. Steady mechanical performance in the low temperature.

5. Good welding performance.

Inconel 718 metallurgical structure.

718 alloy is Austenitic structure, precipitation hardening generate "γ" made it excellent mechanical performance. G rain boundary generate "δ" made it the best plasticity in the heat treatment.

Inconel 718 corrosion resistance.

718 alloy with extremely resistance to stress corrosion cracking and pitting ability in high temperature or low temperature environments, especially the inoxidability in the high temperature.

Inconel 718 application field.
The elevated temperature strength, excellent corrosion resistance and workability at 700°C properties made it use in a wide range of high requirement environments.
1. Steam turbine
2. Liquid-fuel rocket
3. Cryogenic engineering

4. Acid environment

5. Nuclear engineering

Inconel 718 is a Gamma Prime strengthened alloy with excellent mechanical properties at elevated temperatures, as well as cryogenic temperatures. Suitable for temperatures upto around 1300 F. Can be readily worked and age hardened. 

Excellent strength from -423 degrees F to 1300 degrees F (-253 degrees C to 705 degrees C). Age hardenable and may be welded in fully aged condition, Excellent oxidation resistance up to 1800 degrees F (980 degrees C). Typically sold in the solution annealed temper, but can be ordered aged, cold worked, or cold worked & aged. 

Applications

Uses for Inconel 718 tend to be in the field of gas turbine components and cryogenic storage tanks. Jet engines, pump bodies and parts, rocket motors and thrust reversers, nuclear fuel element spacers, hot extrusion tooling. Other popular uses are high strength bolting, and down hole shafting.

 Nickel & cobalt base corrosion, temperature and wear-resistant alloys, such as Inconel 718, are classified as moderate to difficult when machining, however, it should be emphasized that these alloys can be machined using conventional production methods at satisfactory rates. During machining these alloys work harden rapidly, generate high heat during cutting, weld to the cutting tool surface and offer high resistance to metal removal because of their high shear strengths. The following are key points which should be considered during machining operations:

CAPACITY - Machine should be rigid and overpowered as much as possible.

RIGIDITY - Work piece and tool should be held rigid. Minimize tool overhang.
