Mechanical properties:
At room temperature: tensile strength 950 MPa, yield strength 650 MPa, elongation after fracture 18%
At 600°C: tensile strength 880 MPa, yield strength 610 MPa, elongation after fracture 16%
At 800°C: tensile strength 780 MPa, yield strength 580 MPa, elongation after fracture 14%
At 1000°C: tensile strength 620 MPa, yield strength 470 MPa, elongation after fracture 10%

Creep rupture properties:
At 700°C/300 MPa: creep rupture time 1000 hours
At 800°C/250 MPa: creep rupture time 800 hours
At 900°C/200 MPa: creep rupture time 600 hours
At 1000°C/150 MPa: creep rupture time 400 hours

Creep performance:
At 950°C, the creep deformation within 1000 hours is less than 1%.

Fatigue performance:
It can withstand more than 1000 thermal cycles (from room temperature to 950°C).

This alloy maintains high strength within the temperature range of 700 - 1000°C, and its plasticity gradually decreases with increasing temperature. It has excellent creep rupture resistance and creep resistance, making it particularly suitable for high-temperature and high-pressure environments.

Product parameter

Grade: 4033
Steel mills: Haynes; SMC; ATI; VDM; Outokumpu; NYK; Nippon Steel, Fushun/ Northeast Special Steel, etc. 


GH4033 is a nickel-chromium-based superalloy that achieves precipitation hardening by adding aluminum and titanium to form γ’ phase, featuring excellent high-temperature performance and oxidation resistance. It is mainly used in high-temperature structural components such as engine rotors.

High-temperature performance
It can maintain sufficient high-temperature strength for a long time within the range of 700 to 750°C and still has good oxidation resistance below 900°C. Its strengthening mechanism is attributed to the dispersed distribution of γ’ phase (Ni₃(Al,Ti)), which effectively enhances creep resistance at high temperatures.

Mechanical properties
Yield strength ≥ 930 MPa
Tensile strength ≥ 1030 MPa
Elongation ≥ 20%
Fracture toughness ≥ 50 J/cm² (The specific values may vary depending on the processing state)

Processing characteristics
It has good cold and hot working properties and can be formed into complex components through forging, rolling, and other methods. However, during processing, strict control of temperature (such as a narrow forging temperature range) and process parameters is necessary to avoid overheating or cracking.

Application scenarios
It is mainly used in supercritical boiler tubes, gas turbine components, and high-temperature structural parts in the aerospace field, maintaining stable performance in high-temperature environments above 750°C. Please provide the text you would like translated.
