UNS N06625, 2.4856, Alloy 625, Inconel 625 - Made in USA by SMC/ATI/HAYNES
General Properties
Alloy 625 is an austenitic nickel-chromium-molybdenum-niobium alloy offering exceptional corrosion resistance combined with high strength from cryogenic temperatures to 1800°F (982°C). The alloy's strength comes from solid-solution hardening by molybdenum and niobium, eliminating the need for precipitation-hardening treatments.
Key Advantages:
Outstanding corrosion resistance in severe operating environments
Resistance to oxidation and carburization in high-temperature service
Resistant to pitting, crevice corrosion, impingement corrosion, and intergranular attack
Virtually immune to chloride stress corrosion cracking
Easily welded and processed using standard fabrication practices
Electrical Resistivity:50.8 Microhm-in at 70°C (128.9 Microhm-cm at 210°C)
Mechanical Properties at 68°F (20°C)

Corrosion Resistance Performance
Alloy 625 demonstrates exceptional corrosion resistance across various severe environments. The combination of nickel and chromium provides resistance to oxidizing solutions, while nickel and molybdenum offer protection in non-oxidizing conditions.

Fabrication & Processing
Hot Forming
Temperature range: 1650-2150°F (900-1177°C). Heavy working should occur near 2150°F (1177°C) with uniform reductions to prevent duplex grain structure.
Cold Forming
Best performed in annealed condition. Work hardening rates are higher than austenitic stainless steels.
Welding
Readily welded using GTAW (TIG), PLASMA, GMAW (MIG/MAG), SAW and SMAW (MMA) processes. No post-weld heat treatment required.
Machining
Preferably machined in annealed condition. Use low cutting speeds with continuous tool engagement and adequate cut depth to avoid work-hardened zones.
