Inconel Forged Fittings
At Stellanox Steel, we supply a full range of Inconel Forged Fittings built to perform in high-pressure, high-temperature, and severely corrosive environments. Manufactured from top-grade alloys like Inconel 600, 625, 718, and X-750, these fittings provide secure, leak-free connections in demanding applications such as chemical processing, marine systems, aerospace, oil & gas, and nuclear energy.
Available in threaded (NPT/BSP) and socket weld ends, our Inconel forged fittings meet all international specifications including ASME B16.11, MSS SP-83, and ASTM B564.
What are Inconel Forged Fittings?
Inconel Forged Fittings are precision-machined components used to connect pipes in small-diameter, high-pressure systems. Produced through hot forging and controlled machining, these fittings exhibit superior grain uniformity, enhanced mechanical properties, and exceptional resistance to oxidation, acids, and chlorides — especially under cyclic thermal and chemical stress.
Forged fittings are ideal for critical connections in compact assemblies or confined layouts, such as pumps, valves, tanks, and reactors.
