Material Development and Welding

Milestone MS9
“… short-time creep strength better than P91.” The diagram shows that the creep strength is even much better than that of P92. Some of the tests show 20 times longer lifetime than P92, and are still running (arrows).

Upscaling: Large forging (12 t)
Due to the size of the forging the hold times during the heat treatment must be longer than for the laboratory specimens. Hence the mechanical properties are not exactly the same.
