About Alloy
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. Below are the main features
Excellent high-temperature creep behavior values
Outstanding resistance to oxidation at high temperatures, even under cyclical conditions
Very good corrosion resistance in carburizing and oxidizing / chlorinating media
Approval for pressure containers with operating temperatures from -10 to 1,150 °C (14 to 2,102 °F) according to VdTÜV material data sheet 540 and up to 1,650 °F (899 °C) according to ASME Code Section I as well as up to 1,800 °F (982 °C) for applications according to section VIII Div. I.
