Product Description

GH4708 is a Ni-Cr-based precipitation hardening deformed superalloy, and its service temperature is below 850ºC. The alloy is comprehensively strengthened with elements such as tungsten, molybdenum, aluminum and titanium. It has high oxidation resistance, stable structure, and has cold and hot forming and welding process performance. It is suitable for the manufacture of load-bearing parts that work below 850°C in different parts such as combustion chamber, turbine, and adjustable nozzle.

Chemical composition of GH4708:

C: 0.05~0.10

Cr: 17.5~20

Ni: margin

Mo: 4 to 6

W: 5.5~7.5

Al: 1.9 to 2.3

Nb:

Ti: 1.0~1.4

Fe: ≤4.0

Si: ≤0.40

Mn: ≤0.50

P:≤0.015

S:≤0.015

Co:≤0.50

B:≤0.008

Ce: ≤0.030

This standard applies to deformed superalloys, cast superalloys (equiaxed cast superalloys, directionally solidified columnar superalloys and single crystal superalloys), welding superalloy wires, powder metallurgy superalloys, dispersion strengthened superalloys and intermetallic superalloys Compound high temperature material.
