Descripción de producto
Inconel 625 Plates, Sheets, Strips & Coils
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
Industry Applications
- Aerospace Components: Bellows, expansion joints, ducting systems, jet engine exhaust systems, thrust-reversers, turbine shroud rings
- Air Pollution Control: Chimney liners, dampers, flue gas desulfurization (FGD) components
- Chemical Processing: Equipment handling oxidizing and reducing acids, super-phosphoric acid production
- Marine Service: Steam line bellows, Navy ship exhaust systems, submarine auxiliary propulsion systems
- Nuclear Industry: Reactor core components, control rod components, waste reprocessing equipment
- Offshore Oil & Gas: Waste flare gas stacks, piping systems, riser sheathing, sour gas piping and tubing
- Petroleum Refining: Waste flare gas stacks
- Waste Treatment: Waste incineration components

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.
Comparative Corrosion Data
| Alloy | Corrosion Rate (mpy) | Corrosion Rate (mm/a) |
|---|---|---|
| Alloy 625 | 6.8-7.8 | 0.17-0.19 |
| Alloy C-276 | 2.8-2.9 | 0.07-0.074 |
| Alloy 825 | 7.9 | 0.2 |
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.
