Inconel 602 CA

INCONEL 602CA (UNS N06025 / W.Nr. 2.4633) is one of the most oxidation resistant nickel alloys available. Outstanding oxidation resistance is achieved through a high chromium content (25%) supplemented with aluminum (2.2%) and a microalloying addition of yttrium (0.1%). High chromium contents are known to be beneficial for resisting oxidation. The aluminum addition allows for the formation of a continuous homogenous self repairing AI2O3 subscale. The addition of yttrium improves the adhesion and spalling resistance of the chromium and aluminum oxide scales. The extremely low scaling rate of alloy 602CA makes it an excellent candidate for applications such as calciners, where minimal contamination from scaling is permissible.

Extended exposure to methane (CH4), carbon monoxide (CO), and other carbon rich gases can lead to carburization. As heat resistant alloys absorb carbon, their ductility will gradually decrease. Alloys that are high in nickel, such as alloy 602CA possess excellent resistance to carburization attack8. Alloy 602CA forms a tenacious oxide scale, which provides increased protection from carburization. This protective scale impedes the carbon from being absorbed into the base metal.
