Their Inconel 718 Tube Fittings are trusted across various industries, including aerospace, petrochemical, power generation, and offshore engineering, delivering outstanding performance where high pressure and elevated temperatures are everyday challenges.
Inconel 718 Tube Fittings are mainly made up of nickel, chromium, and iron, with notable additions of niobium and molybdenum that boost strength and corrosion resistance. This alloy boasts excellent tensile and yield strength, remarkable creep resistance, and outstanding fatigue performance, even in high-temperature settings. It also shows impressive resistance to oxidation, pitting, and stress-corrosion cracking. Inconel 718 maintains stability during thermal cycling and offers good weldability thanks to its controlled precipitation-hardening process. These combined mechanical and chemical properties make it ideal for tube fittings that face extreme pressures and temperatures.
