Product Description

GH909 belongs to one of the superalloy series.

Because of its high nickel-iron content, accounting for more than 80%, it can also be called iron-nickel-based precipitation hardening deformed superalloy.

The corresponding grades of GH909 are Incoloy 909, GH2909, Pyromet CTX- 909 these kinds.

GH2909 alloy has high strength, high cold and thermal fatigue resistance, low expansion coefficient and constant elastic modulus, as well as good hot working plasticity, cold forming and welding properties. Ferromagnetic, paramagnetic above 450ºC.

Chemical composition of GH909:

Carbon c : ≤0.06

Chromium cr: ≤1.00

Nickel ni: 35.00~40.00

Cobalt co: 12.00~16.00

Aluminum al: ≤0.15

Titanium ti: 1.30~1.80

Iron Fe: Balance

Niobium Nb + Tantalum Ta: 4.30~5.20

Boron B: ≤0.012

Silicon Si: 0.25~0.5

Manganese Mn: ≤1.00

Phosphorus P: ≤0.015

Sulfur S: ≤0.015

Copper Cu: ≤0.500


GH909 density: ρ=8.26g/cm

GH909 alloy will melt in the temperature range of 1336ºC~1384ºC.

This kind of alloy has a low thermal expansion coefficient and a small change rate with temperature.

It can effectively control the gap between engine parts and static parts in a wide temperature cycle, reducing gas Loss, save energy and reduce consumption, improve engine efficiency, extend the life of parts, and carry out shot peening to improve the high-cycle fatigue strength of the alloy in rotating bending.

GH2909 has been used to make gun barrels, gun parts, glass-metal sealing materials, gauge molds and components for high-pressure hydrogen environments.
