Advantages of Using Incoloy 800 Tubing in Aerospace and Defense Applications

High Strength

This product is made from a nickel-chromium alloy that contains small amounts of titanium, aluminium, and carbon. This combination of metals gives Incoloy 800 tube high strength and resistance to creep and stress rupture. Additionally, the tubing has good resistance to oxidation and carburization.

Good Weldability

Incoloy 800 tubing also has good weldability. The tubing can be welded using most standard welding methods, including gas tungsten arc welding, gas metal arc welding, and shielded metal arc welding.

Good Corrosion Resistance

Incoloy 800 tubings have excellent corrosion resistance in both acidic and basic environments. The tubing is especially resistant to corrosion in high-temperature environments. Additionally, the tubing has good resistance to carburization and oxidation.

High Temperature Resistance

Incoloy 800 tubing can withstand high temperatures without losing strength or becoming brittle. The tubing can be used at temperatures up to 1500 degrees Fahrenheit without significant degradation.

Low Thermal Expansion

These products have very low thermal expansion rate. This means that the tubing will not change shape or size when exposed to changes in temperature. This property makes Incoloy 800 tubing ideal for use in aerospace and defense applications where precise dimensions are critical.
