GH2 135

Material grade: GH2 135(GH 135) superalloy.

I. overview of GH2 135(GH 135) superalloy;

GH2 135 superalloy is an age-hardening superalloy composed of Cr, Ni, Mo and other elements, and the nickel content is about 15%. GH2 135 superalloy has good cold and hot workability, good hot strength and hot workability, but poor fatigue performance and machinability. After aluminizing, oxidation resistance can be improved.

2. Chemical composition of GH2135 (GH135) superalloy:? See table 1- 1:

Mechanical properties of GH2 135(GH 135) superalloy:

Tensile strength of 1, GH2 135(GH 135) superalloy: σb (mpa)? ≥800,

2. Conditional yield strength of GH2135 (GH135) superalloy: σ0.2 (mpa)? ≥650,

3. The elongation of GH2135 (GH135) superalloy: δ5 (%)≥ 15,

4. Area shrinkage of GH2135 (GH135) superalloy:? ψ (%)≥20,

5. Hardness of GH2135 (GH135) superalloy: (hb)/mm (pressure D): 3.25-3.65,

6. Heat treatment system of GH2135 (GH135) superalloy: 1080 10℃, 83010℃ for 8h, 70010℃/Kloc.

Four. Main characteristics and applications of GH2 135(GH 135) superalloy;

GH2 135(GH 135) superalloy is an iron-nickel base superalloy independently developed in China, and its other properties have reached and exceeded the level of nickel base alloy gh33 except for its slightly lower fatigue performance. The alloy has good hot working plasticity, but poor machinability; After aluminizing the surface, the ammoniation resistance is better. Practice has proved that the alloy is mature and reliable in use. The service temperature is 500- 1000℃, which is used to manufacture universal load-bearing parts in aviation, aerospace, gas turbine and other industries.
