Nickel Alloys Square Bars Inconel X-750 UNS N07750 W.Nr.2.4669 Round Bar Hexagon Bar

Inconel X-750 Square Bar is a high-performance nickel-chromium alloy that is known for its exceptional resistance to corrosion and heat, as well as its outstanding strength and durability. This square bar, which is available in various sizes and dimensions, is widely used in industries that require materials capable of withstanding extreme environmental conditions.

Here is a detailed description of Inconel X-750 Square Bar:

Composition:

• Inconel X-750 is composed primarily of nickel (approx. 70-75%) and chromium (approx. 14-17%), which provide excellent corrosion resistance and high-temperature strength.
• It also contains aluminum (0.4-1.0%) and titanium (0.4-1.0%), which form a stable oxide layer on the surface of the alloy, enhancing its resistance to oxidation and scaling.
• Other elements include iron, carbon, manganese, silicon, and columbium, which contribute to the alloy’s overall properties.

Characteristics:

• Corrosion Resistance: Inconel X-750 has excellent resistance to a wide range of corrosive media, including salts, oxidizing acids, and alkalis.
• Heat Resistance: The alloy maintains its strength and stability even at high temperatures, making it suitable for use in applications up to 1100°C (2012°F).
• Strength: Inconel X-750 exhibits high tensile strength, which is further enhanced by precipitation hardening heat treatments.
• Ductility: Despite its high strength, the alloy maintains good ductility, allowing it to be formed and machined.

Applications:

• Inconel X-750 Square Bar is commonly used in the aerospace industry for components such as turbine blades, bolts, and other high-stress parts.
• It is also used in the chemical processing industry for components that come into contact with corrosive materials.
• The square bar is suitable for use in gas turbine engines, industrial furnaces, and heat-treating equipment.
• Other applications include fasteners, springs, and various types of hardware that require resistance to high temperatures and corrosive environments.

Fabrication:

• Inconel X-750 Square Bar can be machined using conventional methods, although it may require slower cutting speeds and heavy feeds due to its high strength and work-hardening characteristics.
• Welding can be performed, but it may require post-weld heat treatment to restore the alloy’s properties.
• The square bar can be formed using hot-working techniques, as cold working can make the material more brittle.

Finishes:

• Inconel X-750 Square Bar is often supplied in the solution-annealed and precipitation-hardened condition for optimal mechanical properties.
• It can also be finished with various surface treatments to improve its appearance or to enhance specific properties.

In summary, Inconel X-750 Square Bar is a versatile and rugged material that is well-suited for demanding applications in industries where materials must withstand high temperatures, corrosive environments, and mechanical stress.
