Inconel 602CA is an alloy containing the rare element yttrium. The addition of this element makes the alloy more difficult to smelt, and the content of yttrium is not easy to control. One of the highest performing alloys in nickel-based alloys. The corresponding grades of Inconel 602CA are Alloy 602CA, 2.4633, N06025, ERNiCrFe-12. Its high chromium and high aluminum components enable it to produce dense double-layer protection of chromium oxide and aluminum oxide, and has good oxidation performance. For some industrial fields, it is required to With as little exfoliation oxide as possible to contaminate the product at high temperature, 602CA alloy is often selected for high temperature equipment components in these parts. The accurately controlled carbon composition enables it to have extremely high temperature creep cracking strength, and the addition of a trace amount of zirconium makes it possible to control the grain coarsening when it is in service above 982°C.

Inconel 602CA remains stable for long periods of time at high temperatures up to 2250°F in a cyclic oxidizing environment, has excellent high temperature creep crack strength properties, and is resistant to carbonizing, oxidizing and chlorinating environments.
Inconel 602CA is mainly used in ore calciners, heat treatment retort furnaces, muffle furnaces, fixtures and baskets, chemical vapor deposition bell furnaces, vacuum furnace fixtures, ammonia oxidation furnace catalytic net racks, high temperature processing equipment for molten glass, Radiant tubes, petrochemical reformers and other high temperature oxidation environments.
