Welded Pipe Tube Supplier
Inconel 617 is a nickel-based superalloy that is known for its
excellent high-temperature strength, corrosion resistance, and
oxidation resistance. Some key features of Inconel 617 include:
Composition:
Primarily composed of nickel, chromium, and cobalt, with smaller
amounts of molybdenum, iron, and other elements.
Typical composition: Ni 44-46%, Cr 20-24%, Co 10-15%, Mo 8-10%, Fe
≤3%, Al ≤1.5%, Ti ≤0.6%.
High-Temperature Properties:
Maintains excellent mechanical properties and corrosion resistance
up to temperatures of around 1100°C (2012°F).
Exhibits outstanding creep and stress-rupture resistance at
elevated temperatures.
Corrosion and Oxidation Resistance:
Highly resistant to corrosion in various environments, including
oxidizing, reducing, and high-sulfur atmospheres.
Forms a protective oxide layer that provides excellent resistance
to high-temperature oxidation.
