Inconel 602CA (UNS N06025 / W.Nr. 2.4633) 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 Alloy 602 CA is extremely desirable. A high chromium content, along with aluminum and yttrium additions, allows the alloy to develop a tightly adhering oxide scale.INCONEL alloy 686 is used for resistance to aggressive media in chemical processing, pollution control, pulp and paper manufacture, and waste management applications.
