Essential details

Nimonic PK33 is an alloy that combines nickel and chromium with cobalt and molybdenum for superior heat resistance and creep resistance. It is often used in gas turbines as flame tubes because of its high temperature strength, as well as its ability to be welded into sheet structures. Its features make it ideal for replacing NIMONIC alloys 80A and 90.

Applications:

- Gas turbine welded structures

- Gas turbine hot sections

- Flame tubes

- Enclosures for industrial furnace hot sections

- Combustion chambers
