GH4033 High-Temperature Alloy

Product Overview
GH4033 is a nickel-chromium-based high-temperature alloy with aluminum and titanium added to form γ-phase dispersion strengthening. This alloy demonstrates good high-temperature strength in the range of 700–750°C and excellent oxidation resistance below 900°C. GH4033 has good heating process performance and is mainly used for manufacturing engine rotor components. The alloy is ideal for parts that need to work stably in high-temperature environments for extended periods and offers excellent thermal processing properties, making it particularly suitable for hot rolling and billet supply.

Key Features

• Excellent High-Temperature Strength: The alloy offers sufficient high-temperature strength in the 700–750°C range, making it suitable for high-temperature operating environments.
• Good Oxidation Resistance: GH4033 demonstrates excellent oxidation resistance below 900°C, making it ideal for use in oxidative environments.
• Good Thermal Processing Performance: The alloy is easy to process, suitable for forging, welding, and surface treatment.
• Good Grain Size Control: The grain size is controlled through forging temperature and deformation, enhancing the alloy's microstructure and performance.
• Outstanding Welding Performance: The alloy can be arc-welded in a solution-treated state, but welding stress should be relieved promptly after welding.

Applications

• Aerospace Engines: Used in the production of engine rotor components, especially those that operate under high-temperature conditions.
• High-Temperature Components: Suitable for manufacturing components that must operate in the 700–750°C temperature range for extended periods.
• Gas Turbines: Ideal for manufacturing gas turbine components that require high strength and oxidation resistance.
• Other High-Temperature Applications: Suitable for various industrial devices and components requiring high-temperature resistance, oxidation resistance, and excellent mechanical properties.
