Availability:
Quantity:

Inconel690 is a nickel based high-temperature alloy, mainly composed of elements such as nickel (Ni), chromium (Cr), iron (Fe), molybdenum (Mo), aluminum (Al), titanium (Ti), etc. It has excellent high-temperature strength, good corrosion resistance, and oxidation resistance.

Chemical composition of Inconel690 high-temperature alloy

Nickel: approximately 73%

Chromium (Cr): approximately 30%

Iron (Fe): approximately 10%

Molybdenum (Mo): approximately 1.5%

Aluminum (Al): approximately 0.5%

Titanium (Ti): approximately 0.5%

Inconel690 contains trace amounts of elements such as carbon (C), silicon (Si), manganese (Mn), phosphorus (P), and sulfur (S). Among them, nickel is the main element, which can improve the high-temperature strength and oxidation resistance of the alloy; Chromium can improve the corrosion resistance of alloys; Aluminum and titanium can enhance the high-temperature strength and stability of alloys.
