High Temperature Tube
Product Details

The GH4090 High Temperature Alloy Tube is a premium product designed to perform exceptionally well in high-temperature environments. With its outstanding resistance to thermal expansion, corrosion, and oxidation, this alloy tube is perfect for a range of demanding applications, particularly in chemical processing, marine engineering, and other high-performance industries.
Thermal Expansion Resistance
The GH4090 High Temperature Alloy Tube boasts a thermal expansion rate of 11.2×10⁻⁶/K, making it highly stable and resistant to dimensional changes under extreme temperature fluctuations. This feature ensures the tube will maintain its structural integrity even in environments subject to rapid temperature variations.
High Density and Strength
With a density ranging from 8.2 to 9.4 G/cm³, this high temperature alloy tube provides excellent strength and durability. Its high density makes it resistant to bending, breaking, or deformation under heavy stress, ensuring long-lasting performance in the toughest conditions.
Outstanding Weldability
The GH4090 alloy tube is designed with excellent weldability in mind. It can be easily welded to form reliable, secure joints without the risk of cracking or deformation. This makes it ideal for use in complex installations and demanding applications where weld strength is crucial.
Annealing for Enhanced Durability
Annealed to a strength of 700 – 800 N/mm², the GH4090 tube offers enhanced mechanical strength, ensuring it is ready to withstand extreme conditions in both high-temperature and high-pressure environments. This strength, combined with excellent resistance to oxidation and corrosion, makes it perfect for long-term, high-performance use.
Hot Rolled Alloy Steel Composition
Manufactured from hot rolled alloy steel, the GH4090 High Temperature Alloy Tube benefits from superior strength, durability, and corrosion resistance. This manufacturing process ensures a product that is not only tough but also highly resistant to wear and tear, making it a reliable choice for critical applications.
