Audited Supplier GH3625 Nickel-Based Alloy
Overview of GH3625 features and application areas:
The alloy is a solid solution strengthened nickel-based deformed superalloy with molybdenum and niobium as the main strengthening element. It has excellent corrosion resistance and oxidation resistance. It has good tensile properties and fatigue properties from low temperature to 980 °C, and is resistant to salt. Stress corrosion under fog atmosphere. Therefore, it can be widely used in the manufacture of aero-engine parts, aerospace structural parts and chemical equipment.
GH3625 similar grades:
UNS N06625, Inconel625 (USA), NC22DNb (France), W.Nr.2.4856 (Germany), NS336, 0Cr20Ni65Mo10Nb4
Main ingredients of GH625:
Carbon (C)≤0.01,
Manganese (Mn)≤0.50,
Nickel (Ni)≥58,
Silicon (Si)≤0.50
Phosphorus (P)≤0.015,
Sulfur(S)≤0.015,
Chromium (Cr) 20.0~23.0,

Titanium (Ti) ≤0.4,
Niobium (Nb) 3.15~4.15,
Cobalt (Co) ≤1.0,
Molybdenum (Mo) 8.0~10.0
GH3625 Metallographic structure:
The microstructure of the alloy in the solid solution state is austenite matrix and a small amount of TiN, NbC, and M6C phases. After long-term aging at 650~900ºC, the precipitated phases are γ', δ, M23C6 and M6C.
GH3625 process performance and requirements:
1. The alloy has good cold and hot forming properties, and the heating temperature for ingot forging is 1120 °C.
2. The average grain size of the alloy is closely related to the deformation degree and final forging temperature of the forging.
3. The welding performance of the alloy is good. It can be used for argon arc welding with tungsten electrode or this alloy as filler in a protective atmosphere, and can also be used for brazing connection and resistance seam welding.
4. Surface treatment process: when removing the oxide scale on the surface of the alloy, firstly wash it with alkali, and then pickle it in nitric acid, hydrofluoric acid-water solution.
GH3625 machining and grinding performance:
Use carbide or high-speed steel tools. The cutting tool used should have a positive rake angle. Water-based coolant is recommended for high-speed cutting, and thicker coolant is recommended for low-speed cutting.
GH3625 application areas:
Components of organic chemical process processes containing chlorides, especially where acid chloride catalysts are used;
Digesters and bleaching tanks for the pulp and paper industry;
Absorber tower, reheater, flue gas inlet baffle, fan (humid), agitator, deflector and flue in flue gas desulfurization system;
For the manufacture of equipment and components for use in sour gas environments;
Acetic acid and acetic anhydride reaction generator;
Sulfuric acid condenser, etc.
