2.4665Alloy properties：

The cooling rate in the quenching process of the finished 2.4665 alloy is one of the important factors affecting the alloy process, and the rapid cooling can control the precipitation of the brittle carbide film at the grain boundaries. When the solution temperature of the alloy is higher than 1175°C, it is also easy to form carbide film at the grain boundary. After long-term aging, the alloy shows a certain degree of age hardening, which reduces the plasticity and high-temperature strength.

2.4665Uses of alloys：

HuaNickel 2.4665 alloy is widely used in aerospace and industrial applications.

2.4665Process performance：

Welding performance: The alloy has good welding process performance, and can be welded by argon arc welding, seam welding and spot welding. For TIG welding, it is recommended to use H2.4665 or HGH3113 wire.
