TECHNICAL INFORMATION
Technical Specifications
Detailed technical information including chemical composition, mechanical properties, standards and available dimensions.
Chemical Composition
ASTM B446 holds UNS N06625 inside 20.0–23.0% chromium, 8.0–10.0% molybdenum and 3.15–4.15% niobium plus tantalum, and this flat bar is quoted to that same window. Consequently, those three additions are what hold this flat bar against chlorides and hot acids.
Specifically, the full composition table on the Inconel 625 material page lists every element against its ASTM B446 limit for this flat bar.
Mechanical Properties
ASTM B446 furnishes UNS N06625 rod and bar in two heat-treated grades. Grade 1 (annealed) normally serves up to about 593 °C with higher minimum strength. Grade 2 (solution annealed) normally serves above about 593 °C where creep and rupture resistance matter. Specifically, minimum room-temperature properties appear below; Grade 1 values vary with size.
| Grade / Condition | Product Size | Tensile Strength | Yield Strength, 0.2% Offset | Elongation |
|---|---|---|---|---|
| Grade 1 — Annealed (≥871 °C / 1600 °F) | Up to 101.6 mm (4 in.) dia. | ≥120 ksi (827 MPa) | ≥60 ksi (414 MPa) | ≥30% |
| Grade 1 — Annealed (≥871 °C / 1600 °F) | Over 101.6 to 254 mm (4–10 in.) dia. | ≥110 ksi (758 MPa) | ≥50 ksi (345 MPa) | ≥25% |
| Grade 2 — Solution annealed (≥1093 °C / 2000 °F) | All sizes | ≥100 ksi (690 MPa) | ≥40 ksi (276 MPa) | ≥30% |
- ASTM B446 anneals Grade 1 at 871 °C (1600 °F) minimum. The standard solution anneals Grade 2 at 1093 °C (2000 °F) minimum, with or without a stabilization anneal at 982 °C (1800 °F) minimum to improve sensitization resistance. The applicable ASTM B446 grade, size and condition govern final acceptance.
Physical Properties
Published references place the density of this flat bar near 8.44 g/cm³, with a melting range of 1290–1350 °C. Moreover, those values describe the annealed condition that this flat bar normally ships in.
In addition, the physical properties table on the Inconel 625 material page carries the modulus, the thermal expansion and the remaining design values behind this flat bar.
Standards
ASTM B446 is the principal UNS N06625 bar and rod document for this flat bar, issued by ASTM International. Moreover, ASME SB446 covers pressure equipment built from this flat bar and SAE AMS 5666 covers aerospace procurement.
| Standard | Product or Application |
|---|---|
| ASTM B446 | Nickel-chromium-molybdenum-niobium alloy bar and rod |
| ASME SB446 | ASME counterpart for bar and rod |
| SAE AMS 5666 | Nickel alloy 625 bar, forgings and rings, annealed |
Finally, the full standards list on the Inconel 625 material page adds the European designations and the remaining product documents for this flat bar.

| Forged Flat Bar | 20–150 mm thick × 50–400 mm wide | Custom |
| Strip-Edge Flat Bar | 3–50 mm thick × 10–200 mm wide | Custom |
Available flat bar dimensions depend on the manufacturing route, standard, material condition and order quantity. Please confirm your required flat bar diameter, section and length in the inquiry.
Surface Finishes
Therefore, the surface condition decides how this flat bar machines and how well it holds up in chloride service. Specifically, we agree the finish on this Inconel 625 flat bar with your order.
| Surface Condition | Typical Use |
|---|---|
| Hot Finished | As-hot-worked stock for this flat bar, for parts roughed out before finishing. |
| Peeled | A machined skin on this flat bar with controlled diameter. |
| Polished | Low roughness on this flat bar for product-contact surfaces. |
