Product Description

Product Description

Inconel is a high-performance superalloy primarily based on nickel, designed for applications in extreme environments. It is renowned for its excellent oxidation resistance, corrosion resistance, and high-temperature strength, maintaining mechanical stability and strength at temperatures up to 1000°C (or even higher).

The composition of this alloy typically includes nickel (Ni), chromium (Cr), and iron (Fe), with additional elements like molybdenum (Mo), aluminum (Al), titanium (Ti), and cobalt (Co) added to enhance specific properties. Inconel alloys are widely used in aerospace, energy, petrochemical, marine engineering, and nuclear industries. Common grades such as Inconel 600, 601, 625, 718, and X-750 are tailored for different working conditions and requirements.

Its resistance to high-temperature oxidation and corrosion makes it the material of choice for turbine engines, heat exchangers, chemical processing equipment, and nuclear reactor components in demanding environments.

• Inconel 600: Mainly used in environments that require high temperature and oxidation resistance, such as chemical processing equipment and turbine engines.
• Inconel 625: Known for excellent corrosion resistance, widely used in marine, oil, and gas industries.
• Inconel 718: Commonly used in aerospace and high-temperature engineering applications due to its outstanding high-temperature strength and oxidation resistance

Inconel 725 is a high-strength, corrosion-resistant nickel-chromium-molybdenum alloy that offers excellent resistance to high-temperature oxidation, general corrosion, and stress corrosion cracking. This alloy is especially well-suited for demanding applications in industries such as aerospace, chemical processing, and marine, where high temperature and high stress resistance are crucial.

Inconel 725 is commonly used in environments where both strength and resistance to aggressive media are essential, making it ideal for use in extreme temperature and high-pressure applications.

Key Properties

• High Strength: Inconel 725 demonstrates excellent tensile, yield, and creep-rupture strength, even at elevated temperatures. This makes it suitable for critical applications under high-stress conditions.
• Corrosion Resistance: It offers superior resistance to a wide range of corrosive environments, including sulfur-containing environments, seawater, and many acids.
• Oxidation Resistance: The alloy provides exceptional resistance to oxidation and scaling at high temperatures, making it suitable for use in environments with elevated temperatures (up to 1,500°F or 815°C).
• Stress Corrosion Cracking Resistance: Inconel 725 resists stress corrosion cracking in high-temperature environments, which is a significant advantage in industries like aerospace and chemical processing.
• Weldability: Inconel 725 can be welded using various welding techniques. However, due to its high strength, pre-heat and post-weld heat treatment are often required to prevent cracking.
• Excellent Fatigue Resistance: The alloy's excellent fatigue resistance makes it ideal for components that are subjected to cyclic loading and dynamic forces.

Fabrication and Machining

• Welding: Inconel 725 can be welded by various methods, including Gas Tungsten Arc Welding (GTAW), Gas Metal Arc Welding (GMAW), and Shielded Metal Arc Welding (SMAW). However, the alloy's high strength necessitates pre-heat and post-weld heat treatment to prevent cracking.
• Machining: Due to its high strength, Inconel 725 can be challenging to machine, especially in the cold-worked state. Carbide tooling and lower cutting speeds may be required to achieve clean cuts and avoid rapid tool wear.
• Cold Working: The alloy can be cold worked, but it tends to work-harden rapidly, so appropriate tooling and equipment should be used.
• Hot Working: Hot working of Inconel 725 should be performed in the temperature range of 1,600°F to 2,000°F (871°C to 1,093°C) to ensure good formability and avoid work-hardening.
