Incoloy Alloy 625 sheet's core strength is derived from a solid-solution hardening effect. The atomic matrix consists of a nickel-chromium base, but it is heavily infused with Molybdenum (8.0% – 10.0%) and Niobium (3.15% – 4.15%). These larger atoms distort the crystalline lattice of the nickel matrix, acting as natural speed bumps against atomic slip (deformation).
We offers Incoloy Alloy 625 in a variety of forms, including:
- Bar
- Wire
- Sheet
- Plate
- Forgings
- Pipe fittings
- Flanges

Formability vs. Yield: Working with Alloy 625
From a fabrication standpoint, ordering Alloy 625 sheet means preparing your machine shop for rapid work-hardening. While the material is highly ductile and can be cold-formed into complex geometries, bellows, or heat exchanger plates, it demands rigid machine setups and powerful press brakes.
Key Mechanical Design Benchmarks (Annealed Grade 1 Sheet)
| Property | Value (Imperial) | Value (Metric) |
| Ultimate Tensile Strength | 120 ksi (Min) | 827 MPa (Min) |
| 0.2% Yield Strength | 60 ksi (Min) | 414 MPa (Min) |
| Elongation at Break | 30% (Min) | 30% (Min) |
| Density | 0.305 lb/in³ | 8.44 g/cm³ |

Because its yield strength is roughly double that of standard 304 or 316 stainless steel, expect higher springback during bending operations. Heavy-duty lubrication and continuous tool engagement are mandatory to prevent the sheet from glazing over and destroying cutting edges.
