Inconel 625 Suppliers

Inconel 625 Industrial Fittings – Buttweld, Forged & Outlet Range with Flanges. ISO 9001:2015 Certified | Worldwide Delivery.

With a reputation for delivering high-performance materials for extreme service conditions, we provide a wide portfolio of nickel alloys, stainless steels, and corrosion-resistant products. One of our flagship offerings is Inconel 625, a nickel-chromium-molybdenum alloy designed for outstanding strength and corrosion resistance in severe environments. Its balanced composition, including nickel (~58%), chromium (~20–23%), molybdenum, and niobium, gives it excellent mechanical properties and protection against a wide range of corrosive agents, making it ideal for aerospace, marine, nuclear, and chemical industries.

Our Inconel 625 product line includes a broad selection of flanges (weld neck, blind, slip-on, lap joint, threaded, socket weld), buttweld fittings (long/short radius elbows, tees, concentric/eccentric reducers, caps), and forged fittings (socket weld and threaded elbows, tees, unions, couplings). We also offer specialty branch fittings such as weldolets, sockolets, and threadolets for high-integrity piping connections. All products are precision-manufactured following international standards like ASTM B564, B366 and dimensional codes including ASME/ANSI B16.5, B16.9, and B16.11, ensuring consistent quality and fitment.

Inconel 625 provides exceptional mechanical strength, with a minimum tensile strength of 827 MPa (120 ksi) and yield strength of 414 MPa (60 ksi). It remains structurally stable across a broad temperature range — from cryogenic conditions to 982°C (1800°F). The alloy’s resistance to pitting, crevice corrosion, and stress corrosion cracking in seawater and aggressive chemicals is outstanding. We offer Inconel 625 items in sizes from ½” NB to 48” NB, with pressure classes including 150# to 2500# for flanges and 3000#, 6000#, 9000# for forged fittings. Every product is quality-checked under a strict ISO 9001:2015 certified quality system, including PMI testing, hydro testing, and ultrasonic inspection.

Inconel 625 is widely used in offshore platforms, exhaust systems, nuclear reactor components, acid processing equipment, and aerospace engines due to its high strength, weldability, and resistance to oxidizing and reducing environments. Key benefits include resistance to chloride-ion stress corrosion, long service life under thermal cycling, excellent fatigue strength, and weldability without post-weld heat treatment. The alloy’s performance in both oxidizing and reducing environments makes it highly reliable for mission-critical operations where durability and safety are non-negotiable.
