Inconel 625 Nickel Superalloy Powder
Nickel & Superalloy Powders · Metal Additive Manufacturing Powder
Inconel 625 (UNS N06625, GH3625 in China) is a nickel-chromium-molybdenum superalloy prized for corrosion resistance in seawater, chemical processing and aerospace exhaust environments. Unlike 718, its strength comes primarily from solid-solution strengthening, which makes it easier to print crack-free and requires only stress relief or solution annealing after printing. Published LPBF data show as-built Inconel 625 at 922 MPa UTS and 610 MPa YS with 40% elongation — an excellent strength-ductility balance. Gas-atomized powder in 15-45 µm and 15-53 µm cuts is standard; buyers in marine applications should request chemistry per ASTM B443 with molybdenum 8-10% and niobium 3.15-4.15% verified on the mill certificate.

Frequently Asked Questions
How much does Inconel 625 powder cost?
Inconel 625 AM powder typically quotes $90-170 per kg. Request current quotes from verified suppliers on this page — responses usually within 24 hours.
Does Inconel 625 need heat treatment after printing?
A stress relief (870°C) or solution anneal (1,050-1,150°C) is standard. Because 625 is solid-solution strengthened, it does not require the double ageing of Inconel 718.
Is Inconel 625 suitable for seawater applications?
Yes — its high molybdenum content resists pitting and crevice corrosion in seawater, making printed 625 popular for marine propellers, pump impellers and subsea tooling.
Which particle size should I order?
15-45 µm for fine LPBF work, 15-53 µm general purpose, 45-106 µm for EBM or DED. Specify your machine in the inquiry for a matched recommendation.
What certifications are available for 625 powder?
Professional suppliers provide mill certificates per ASTM B443 with full chemistry, particle-size distribution and oxygen analysis. State 'full MTC required' in your inquiry.
