Nickel Alloy Monel K500 Tubes – Best Choice for High-Temperature Applications, China Nickel Alloy Monel K500 Tubes – Best Choice for High-Temperature Applications Manufacturers, Suppliers, Factory

Introduction to Monel K500 Tubes

Monel K500 tubes are high-strength, corrosion-resistant nickel alloy tubes specifically designed for high-temperature and high-pressure environments. These tubes combine the exceptional corrosion resistance of Monel 400 with greater mechanical strength due to precipitation hardening.

With their ability to withstand extreme temperatures, aggressive chemicals, and seawater conditions, Monel K500 tubes are an ideal choice for aerospace, marine, oil & gas, and chemical processing industries.

Material Overview – Monel K500 (UNS N05500)

Monel K500 is a nickel-copper alloy that includes aluminum (Al) and titanium (Ti) to enable age hardening, enhancing its mechanical properties. It offers superior resistance to corrosion, oxidation, and high-temperature environments, making it well-suited for demanding applications.

Chemical Composition of Monel K500

Nickel (Ni): 63.0% min
Copper (Cu): 27.0-33.0%
Aluminum (Al): 2.30-3.15%
Titanium (Ti): 0.35-0.85%
Iron (Fe): ≤ 2.0%
Manganese (Mn): ≤ 1.5%
Carbon (C): ≤ 0.25%
Silicon (Si): ≤ 0.50%
Sulfur (S): ≤ 0.010%
