Alloy 602 CAMaterial
Alloy 602 CA, UNS N06025, W.Nr. 2.4633
Overview
Alloy 602 CA is a high-temperature material with excellent resistance to creep and oxidation up to 1200°C (2192°F). It is usually delivered in the solution-annealed state with an oxidized or descaled surface.
Characteristics
The materialis characterized by
(1) Excellent high-temperature creep behavior values
(2) Outstanding resistance to oxidation at high temperatures, even under cyclical conditions
(3) Very good corrosion resistance in carburizing and oxidizing / chlorinating media
(4) Approval for pressure containers with operating temperatures from -10 to 1150 °C (14 to 2102 °F) according to VdTÜV material data sheet 540 and up to 1650 °F (899 °C) according to ASME Code Section I as well as up to 1800 °F (982 °C) for applications according to section VIII Div. I..
Application
Alloy 602 CA has a wide range of application in the high-temperature field of thermo technical and chemical processes, in power plants and in the automotive industry.

Corrosion Resistance
Alloy 602 CA is especially characterized by very good oxidation resistance, which is better across the entire application range up to 1200°C (2192°F) than with Alloy 601. Even under extreme conditions, such as cyclic heating and cooling, Alloy 602 CA retains this property, which is caused by a tight and adhering alumina layer, which is very resistant to chipping.
High temperature oxidation tests show that, compared to other high temperature materials, this material has the lowest mass loss under cyclic stress. Caused by its chromium and aluminum content, Alloy 602 CA is also highly resistant in oxidizing sulfur-containing atmospheres at elevated temperatures.
