Pickling Finish Annealed Inconel 690 Nickel Based Alloy Rod for Steam Generators
Super alloys have good creep and oxidation resistance. They are also known as high performance alloys, and can be formed in different shapes. Work hardening, precipitation hardening, and solid-solution hardening are performed for strengthening the super alloys. These alloys have the capcity to function at very high temperatures and severe mechanical stress, and also where high surface stability is required.
Inconel 690 is a nickel-chromium alloy. It has high resistance to hot gases or oxidizing chemicals due to the presence of high chromium content. The following datasheet gives an overview of Inconel 690.
The chemical composition of Inconel 690 is outlined in the following table.
