Product Description
Inconel Alloy 625 is a nickel-chromium-molybdenum alloy with a controlled addition of niobium. Strength is achieved through solid-solution hardening by molybdenum and niobium, eliminating the need for age hardening.
ASTM B446 covers both Grade 1 (annealed) and Grade 2 (solution annealed) conditions, delivering reliable performance from cryogenic temperatures up to approximately 980 °C (1800 °F). The alloy exhibits excellent resistance to pitting, crevice corrosion, and chloride-induced stress corrosion cracking, making it a preferred choice for seawater, sour gas, and aggressive chemical service.
Outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking in chloride environments
High tensile and yield strength without precipitation hardening (solid-solution strengthened)
Excellent weldability with no requirement for post-weld heat treatment in most applications
Superior oxidation and corrosion resistance in both oxidizing and reducing media
Stable mechanical properties from cryogenic to elevated temperatures
Good fabricability – easily machined, formed, and welded
Compliant with ASTM B446, ASME SB-446, AMS 5666, and related international standards
Available in annealed (Grade 1) and solution-annealed (Grade 2) conditions

Application Field
Oil & Gas / Subsea – Wellhead components, valve stems, pump shafts, riser connectors, and sour-service equipment (NACE MR0175 compliant)
Marine & Offshore – Propeller shafts, seawater pump components, fasteners, and hardware exposed to continuous seawater
Chemical Processing – Reactor internals, agitator shafts, heat exchanger parts, and equipment handling mixed acids
Aerospace – Exhaust systems, ducting, turbine components, and high-strength fasteners
Nuclear & Power Generation – Reactor core support structures, steam generator components, and high-temperature hardware
Pollution Control – Flue gas desulfurization (FGD) system components and stack hardware
The combination of strength, corrosion resistance, and weldability makes Inconel 625 round bar ideal for both new construction and critical replacement parts.

FAQ
Inconel 625 is a nickel-chromium-molybdenum-niobium alloy identified as UNS N06625 and Werkstoff 2.4856. It is supplied in bar and rod form for components requiring a combination of strength, fabricability and corrosion resistance.
Please provide the required diameter, length, quantity, material condition, applicable specification, delivery destination and any inspection-document requirements. These details help us confirm availability and prepare an accurate quotation.
Availability depends on the requested dimensions and supply condition. Contact DLX Alloy with your requirements to confirm the options for your order.
Suitability for hydrogen service depends on the pressure, temperature, gas environment, loading conditions, material condition and applicable design requirements. The alloy designation alone does not establish that a component is suitable for a specific hydrogen system. Please provide the service conditions for technical review.
Mechanical properties depend on the product form, dimensions, material condition and governing specification. Please request the applicable values and test documents for the material offered for your order.
