3.Chemical Properties
Higher yield strength and rupture strength until 650 ℃, good oxidation resistance until760 ℃,
organizational stability of long-term use.
The alloy is a more mature alloy of the early development , widely used in the work of manufacturing
air and ground gas turbine engine rotating disc (turbine and compressor disk, journal, etc.), the static structure,
turbine outer ring, fasteners, components ,until 650 ℃.

5.Applications and special requirements
This alloy is widely used in aero-engine in work rotating parts and fasteners of foreign countries and
the ground gas turbine until 650 ℃ , a longer service life.
Home, it also has been used on aircraft engine, which is a mature alloy through using test.
Alloy forging , if process parameters selection or operation is improper, its performance will show
obvious directivity, and may cause sensitive gap, but as long as the process strictly, the phenomenon .
won't appear. Expansion coefficient of the alloy is close to heat intensity alloy steel, iron element size,
which makes it possible to connect two kinds of materials in the face of hot account without special provisions. |
