Inconel X-750 Suppliers

Inconel X-750 Buttweld Fittings, Forged Fittings & Flanges – ISO 9001:2015 Certified – Ready Stock for Worldwide Delivery.

We are a trusted and ISO-certified supplier of Inconel X-750 fittings, flanges, forged components, and outlet fittings, serving clients across aerospace, petrochemical, and power generation industries. Manufactured to the highest global standards, our product range includes buttweld fittings, forged fittings, flanges, and olets designed to perform in high-temperature and high-stress environments. With a strong inventory and in-house machining capabilities, we cater to urgent project requirements and export globally.

Inconel X-750 is a precipitation-hardened nickel-chromium alloy with excellent creep resistance, high strength, and corrosion resistance at elevated temperatures up to 1300°F (700°C). It conforms to specifications such as ASTM B637, AMS 5667, AMS 5669, and ASME B16.5, B16.9, B16.11. Our fittings and flanges are available in pressure classes ranging from 150# to 2500#, and in SCH 10 to SCH XXS, ensuring compatibility with a wide variety of systems and applications.

We supply a comprehensive range of Inconel X-750 buttweld fittings including elbows (90°/45°), tees, concentric/eccentric reducers, and caps. Our forged fittings include socket weld and threaded types like couplings, unions, and elbows as per ASME B16.11. The flanges offered include WNRF, SORF, BLRF, SWRF, and threaded types, manufactured in sizes from ½” to 24″. In addition, we stock a variety of olets such as weldolets, sockolets, and threadolets for branch connections.

All products undergo strict quality checks including PMI, ultrasonic testing, and dimensional inspection. We offer third-party inspection (TPI) services from agencies like BV, SGS, and TUV on request. Fittings and flanges are packed in fumigation-certified wooden boxes with proper labeling and heat numbers for traceability. With a global export network, we supply to clients across the USA, Europe, Middle East, and Asia. Timely delivery and material traceability are our key commitments.
