TECHNICAL INFORMATION FOR NICKEL 783
INCONEL 783 is a nickel-based superalloy for high-performance components in gas and steam turbines, providing improved resistance to oxidation and low thermal expansion, with a high strength level maintained up to elevated temperatures. This makes it suitable for difficult applications in aerospace and power generation.
General OverView
Nickel 783 (UNS R30783) is a nickel-chromium super alloy strengthened through a precipitation-hardenable alloy containing niobium and aluminum as additions. The aluminum addition provides enhanced oxidation resistance, and the niobium addition maintains high-temperature properties at elevated levels. INCONEL 783 compares favorably in property and cost if you need a material a little lighter in density, around 5% down from the density of INCONEL 718.
This alloy also exhibits an exceptionally low coefficient of thermal expansion. This helps you achieve tighter clearances and tolerances in your turbine parts. This means you get enhanced performance, efficiency in fuel use, and component longevity.
Applications of INCONEL 783
INCONEL 783 is used in:
- Gas turbine structural components such as blades, frames, and vanes.
- Steam turbine components requiring precise tolerances and high strength.
- High-temperature aerospace hardware.
- Power generation equipment needing oxidation-resistant materials.
