UNS Number N06025

Inconel 602 is the most oxidation resistant/high strength nickel alloy available. It is capable of extreme temperature use up to and beyond 2200°F (1200°C). For thermal processing applications where minimal product contamination is necessary, the oxidation/scaling resistance of Inconel 602 is extremely desirable. A high chromium content, along with aluminum and yttrium additions, allows the alloy to develop a tightly adhering oxide scale.

A relatively high carbon content combined with the alloying additions of titanium and zirconium results in high creep rupture strength.
