Overview


Alloy 602CA is a high carbon chromium-iron-nickel alloy which also contains additives of microalloy elements titanium, zirconium and aluminum, and yttrium.

Inconel 602CA 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.

Corrosion Resistance


Inconel 602CA is a high temperature corrosion resistant alloy with excellent corrosion resistance. This alloy has good corrosion resistance to sulfide environments and can be used for applications in sulfur-containing media. At the same time, Inconel 602CA is also resistant to acid, alkali, chlorine and other strong corrosive media. In addition, due to its low carbon content and stabilization heat treatment, it still does not have a tendency to sensitize even after 50 hours of high temperature insulation at 650~900 ° C, which further enhances its corrosion resistance.


Inconel 602CA has demonstrated excellent corrosion resistance in a variety of corrosive environments, making it widely used in many fields, such as furnace internals, heat treatment furnaces, burner components, lead smelting equipment, slag tanks and other high temperature environment corrosion resistance equipment.



Heat Treatment


The heat treatment process of Inconel 602CA mainly includes solution treatment, quenching treatment, process tempering and precipitation hardening treatment.


First, solution treatment is a key step to improve its corrosion resistance and oxidation resistance. This usually needs to be carried out at a temperature of 1150 ° C to 1200 ° C, and cooled quickly in the air to maintain the uniform structure of the alloy. Solid solution treatment can dissolve carbides and other phases in the alloy in the matrix, which is helpful to improve the toughness and ductility of the alloy.


Secondly, quenching treatment is carried out after solid solution treatment, usually water quenching treatment between 850 ° C and 900 ° C, which can further increase the hardness and strength of the material. However, attention should be paid to avoid excessive cooling resulting in increased brittleness of the material.


In addition, after cold deformation or quenching treatment, Inconel 602CA can also be processed and tempered to eliminate stress and improve the toughness of the material. Tempering temperature and time can be selected according to specific requirements.


Finally, precipitation hardening can significantly improve the tensile strength and yield strength of Inconel 602CA. Commonly used precipitation hardening treatment methods include high temperature aging treatment between 850 ° C and 1000 ° C, and low temperature aging treatment.
