PRODUCT OVERVIEW
About Inconel 625 Bar and Rod
Inconel 625 bar and rod is a solid-solution-strengthened nickel-chromium-molybdenum alloy. Moreover, it keeps very high strength in seawater, hot acids and high-temperature gas paths up to about 980 °C. Therefore, fabricators specify Inconel 625 bar for marine, aerospace, chemical, oil and gas and power-generation parts.
PRODUCT FEATURES
Key Features of Inconel 625 Bar and Rod
Inconel 625 bar and rod is a nickel-chromium-molybdenum-niobium alloy. Solid-solution hardening gives it very high strength. It resists pitting, crevice corrosion and chloride stress-corrosion cracking. UNS N06625 is supplied to ASTM B446 / ASME SB446. Sections include round, square, hex, flat and forged bar for marine, aerospace, chemical, oil and gas and power use.

We convert the ingot to billet, then forge or hot roll it to the required bar and rod section with controlled working.
05
Solution Annealing
Annealing develops the specified balance of strength, ductility and corrosion resistance for the ordered condition.

Chemical Composition
The composition limits below follow published ASTM B446-related data for UNS N06625. However, the governing purchase specification always takes precedence for final acceptance on the bar and rod range.

| Iron (Fe) | 5.00% max. |
| Cobalt (Co) | 1.00% max. |

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 and carries higher minimum room-temperature strength; Grade 2 (solution annealed) normally serves above about 593 °C where the design needs creep and rupture resistance. Minimum room-temperature properties are listed below — Grade 1 requirements vary with product 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% |
- Grade 1 requires annealing at 871 °C (1600 °F) minimum. Grade 2 requires solution annealing at 1093 °C (2000 °F) minimum, with or without a subsequent stabilization anneal at 982 °C (1800 °F) minimum to increase sensitization resistance. The applicable ASTM B446 grade, size and condition govern final acceptance.
