Alloy 690

UNS N06690

 

GENERAL PROPERTIES

Alloy 690 is a nickel-chromium alloy. It has high resistance to hot gases or oxidizing chemicals due to the presence of high chromium content. 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 capacity to function at very high temperatures and severe mechanical stress, and also where high surface stability is required.

 

MACHINEABILITY

Alloy 690 can be machined using conventional machining methods which are used for iron-based alloys. Machining operations are performed using commercial coolants. High-speed operations such as grinding, milling or turning, are performed using water-base coolants.
