ATI Cobalt 188™

Generic Family: Cobalt - Wrought - AlloySupplied by: Allegheny Technologies Incorporated
The ATI 188™ alloy is a cobalt-based, solid-solution strengthened alloy that has excellent high temperature strength, excellent oxidation resistance up to 2000°F (1093°C), and good sulfidation resistance. This alloy also has good forming and welding characteristics, which make it useful in fabricating gas turbine components such as combustion cans and transition ducts.

The alloy has a face-centered cubic structure. High tungsten content provides solid solution strengthening, while the precipitation of M6C and M23C6 carbides further increases the strength. High chromium content and the addition of lanthanum promote oxidation resistance through formation of a tenacious oxide.
