Product Description

GH2135 is a Fe-Ni-Cr-based precipitation hardening deformed superalloy, and the operating temperature is below 700ºC.

Elements such as aluminum and titanium are added to the alloy to form an aging precipitation strengthening phase, and elements such as chromium, tungsten and molybdenum are added for solid solution strengthening.

The alloy has good resistance to low cycle pi. The yield strength increases with the increase of temperature below 700ºC, and the hot working plasticity is good. The main products are dry materials, plates, forgings and so on.

The alloy has been used to make two types of aero-engines, grades I and II, vortex lunpan, and two types of fighter jets are used in the field.

The flame direction of my country's 3,000-horsepower gas turbine made of alloy plates was installed on the Long March No. 1 machine tool and passed the test of more than 300 hours of operation.

The alloy can also be used to make hot forming dies that work at 750ºC-850ºC, such as forging hammer anvils and hydraulic press Fengzi or insert anvils, hot stamping dies, etc.

Compared with nickel-based alloys for similar purposes, GH2135 alloy can save Ni41% and Cr5.5%.

After long-term aging above 800ºC, needle-shaped σ phase is precipitated in the alloy, and Laves phase is precipitated at the grain boundary.

GH135 is an iron-nickel-based superalloy developed by our country.

Except for the slightly lower fatigue performance, the rest of the properties have reached and exceeded the level of nickel-based alloy gh33.

The alloy has good hot working plasticity, but poor machinability; after surface aluminizing, it has good smear resistance.

Practice has proved that the alloy is relatively mature and reliable in use.

The use temperature is 500-1000 ºC, and it is used to manufacture general load-bearing parts for aviation, aerospace, gas turbines and other industries.
