Inconel 602CA Alloy Sheet

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.

Physical Properties

Mechanical Properties

High-temperature strength: Inconel 602CA exhibits excellent strength and mechanical properties at elevated temperatures, making it suitable for applications in extreme heat environments.
Oxidation resistance: The high chromium content in Inconel 602CA provides exceptional resistance to oxidation, enabling it to withstand high-temperature oxidizing atmospheres.
Carburization and sulfidation resistance: This alloy demonstrates good resistance to carburization and sulfidation, which are processes involving the diffusion of carbon and sulfur into the material at high temperatures. This resistance is beneficial for applications in petrochemical, chemical, and power generation industries.
Creep resistance: Inconel 602CA has good resistance to creep deformation, which is important for applications subjected to prolonged exposure to high temperatures and constant stress.
Weldability: Inconel 602CA can be readily welded using common welding techniques, allowing for the fabrication and repair of components.
