About 602 CA®

602 CA® has a high creep rupture strength, providing up to 150% of the strength of other nickel alloys. Exposure to carbon rich gases can cause carburization. Due to its high nickel content, 602 CA® has an outstanding resistance to carburisation, ensuring prolonged ductility in the face of carbon monoxide (CO) and methane (CH4).

Performing well under high pressure and temperature, 602 CA® is extensively used in thermal processing equipment.

602CA® is the registered trademark of VDM Metals International GMBH.
