Characteristics and main uses of GH high temperature alloy

GH alloy is a high-temperature alloy, mainly composed of nickel (Ni), chromium (Cr), molybdenum (Mo), iron (Fe) and other elements. It has excellent high-temperature strength, creep resistance and oxidation resistance, and is widely used in aerospace, petrochemical, nuclear engineering, electric power and other fields. The chemical composition of GH4751 (GH751) includes: nickel (Ni) about 55-59%, chromium (Cr) about 19-22%, molybdenum (Mo) about 8-10%, iron (Fe) about 7-9% and other elements. The reasonable ratio of these elements makes GH4751 have excellent high-temperature performance.

The characteristics of GH high-temperature alloy are as follows:

1. High temperature strength: GH high temperature alloy has excellent high temperature strength, can maintain the stability of its mechanical properties in high temperature environment, and withstand the challenges of high temperature environment. It has high yield strength and tensile strength, and can withstand heavy loads at high temperature.

2. Creep resistance : GH high temperature alloy has excellent creep resistance, and can maintain the stability of its shape and strength under high temperature and high stress conditions. Creep resistance is one of the important indicators to measure the quality of high temperature alloy materials, and GH high temperature alloy performs well in this regard.

3. Oxidation resistance : GH high temperature alloy has excellent oxidation resistance and can resist oxidation and corrosion erosion in high temperature environment. The oxide layer it forms can effectively protect the substrate and extend the service life of the material.
