INCONEL 625 is a nickel chromium molybdenum niobium alloy valued for strength and broad corrosion resistance. Molybdenum and niobium strengthen the matrix without requiring a precipitation-hardening treatment for normal use. Its fabrication versatility supports both welded structures and tubular products. Marine, chemical and aerospace components use the alloy where corrosion exposure and mechanical demand must be addressed together.
Chemical composition
| Element | Weight percent | Element | Weight percent |
| Ni | 58.0 min | Cr | 20–23 |
| Mo | 8–10 | Nb + Ta | 3.15–4.15 |
| Fe | 5.0 max | C | 0.10 max |
| Mn | 0.50 max | Si | 0.50 max |
| P | 0.015 max | S | 0.015 max |
| Al | 0.40 max | Ti | 0.40 max |
| Co | 1.0 max, if determined | — | — |
Mechanical properties
Nominal room-temperature property ranges from Special Metals Table 5; composite data for product sizes up to 4 inches. Elongation ranges are shown in ascending order.
| Product / condition | 0.2% yield MPa | Tensile MPa | Elongation % |
| Bar / plate, annealed | 414–655 | 827–1034 | 30–60 |
| Bar / plate, solution treated | 290–414 | 724–896 | 40–65 |
| Sheet / strip, annealed | 414–621 | 827–1034 | 30–55 |
| Cold-drawn tube, annealed | 414–517 | 827–965 | 30–55 |
| Cold-drawn tube, solution treated | 276–414 | 689–827 | 40–60 |
Annealed and solution-treated conditions differ; select the grade and thermal condition required by the product standard.
Application areas
- Marine hardware and seawater components
- Chemical processing equipment
- Aircraft exhaust and other aerospace structures
- Corrosion-resistant piping and heat exchangers
