Nimonic PK33

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.
