Inconel 718 alloy tube is a nickel-chromium alloy characterized by excellent high temperature strength, oxidation resistance and corrosion resistance. It maintains good mechanical properties at high temperatures up to 700°C, which makes it widely used in high temperature parts such as turbine blades and combustion chambers of aircraft engines.
Inconel 718 alloy tube implementation standards
The production and use of Inconel 718 steel pipes must comply with relevant international and domestic implementation standards, including but not limited to ASTM B637, AMS 5662 and AMS 5663.
The physical and mechanical properties of Inconel 718 seamless alloy tubes are excellent, as follows:
Density: about 8.19 g/cm³, which gives it a high strength-to-weight ratio.
Thermal conductivity: The low thermal conductivity (about 11.3 W/m·K) makes it have good insulation performance at high temperatures.
Elastic modulus: about 200 GPa, enough to withstand ultra-high workloads.
Tensile strength: It can reach 1034 MPa at room temperature and 1379 MPa after heat treatment, showing excellent strength.
Toughness: Good toughness ensures that it is not easy to break under collision or impact load.
Wide application of Inconel 718:
Aerospace: Used to manufacture turbine blades, combustion chambers and components of aircraft engines, capable of withstanding extreme temperatures and pressures.
Petrochemical: Equipment used in high temperature and high pressure environments required in oil exploration and refining.
Nuclear energy: Suitable for high temperature areas and accessories in nuclear reactors, with excellent radiation resistance.
Heat exchanger: Suitable for heat exchangers in chemical media environments such as fluorides and styrene.
