PRODUCT OVERVIEW
About Hastelloy B-2 Forged Bar
Hastelloy B-2 forged bar arrives in UNS N10665, the nickel-molybdenum grade that holds hydrochloric acid at every concentration up to boiling. Replacement internals, column trays and non-welded machined parts make up most of the orders we ship for this forged bar.
Forged bar follows ASTM B564 instead, because this grade leaves the B335 rod ceiling above 88.9 mm. Each consignment of this Hastelloy B-2 forged bar leaves with heat-number records, a solution-anneal record and EN 10204 3.1 paperwork for goods-in checks. Besides, we settle the anneal cycle and the finish for this forged bar before a heat leaves the furnace.
Meanwhile, the Hastelloy B-2 material page holds the chemistry and the mid-temperature limits behind this Hastelloy B-2 forged bar for cross-reference.
PRODUCT FEATURES
Key Features of Hastelloy B-2 Forged Bar
Hastelloy B-2 forged bar arrives in UNS N10665, the nickel-molybdenum grade whose molybdenum sits at 26.0–30.0% while chromium stops at 1%, so hydrochloric acid at any concentration meets a surface it cannot oxidise. We supply ASTM B335 forged bar as forged and solution annealed, with the reduction ratio recorded on the release for hydrogen chloride synthesis, steel pickling lines and acid regeneration hardware. Every Hastelloy B-2 forged bar consignment travels with heat-number traceability, EN 10204 3.1 mill test reports and full export documentation.
Hastelloy B-2
Hydrochloric Acid Coverage
For example, molybdenum at 26.0–30.0% lets this Hastelloy B-2 forged bar serve acid at every concentration up to boiling.
01
One-to-One Replacement
Specifically, a spare in this Hastelloy B-2 forged bar matches the metallurgy of the grade already installed in your plant.
02
Oxidant-Free Duty Only
Therefore, nitric acid, ferric ion and hypochlorite rule this Hastelloy B-2 forged bar out, so those lines need a chromium-bearing alloy.
03
Cold Work Sets Strength
In addition, no aging treatment exists for this Hastelloy B-2 forged bar, so proof stress above the annealed floor comes from drawing alone.
04
Quench-Controlled Anneal
Besides, we hold this Hastelloy B-2 forged bar between 1065 and 1095 °C and water quench it, because Ni4Mo forms between 540 and 815 °C.
05
Non-Magnetic in Service
Consequently, instrument assemblies sit comfortably with this Hastelloy B-2 forged bar because the annealed matrix stays non-magnetic.
06
No Aerospace Route to Check
Finally, no aerospace specification reaches this grade, so this Hastelloy B-2 forged bar goes out against the ASTM document alone.
07

TECHNICAL INFORMATION
Technical Specifications
Detailed technical information including chemical composition, mechanical properties, standards and available dimensions.
Chemical Composition
Molybdenum runs 26.0–30.0% in this forged bar under the B335 composition table, the highest molybdenum level any wrought nickel alloy carries. Besides, chromium stops at 1.0% maximum and iron at 2.0% maximum, so a reducing acid meets a surface with nothing it can oxidise.
For the element-by-element limits behind this forged bar, open the composition breakdown held on the Hastelloy B-2 material page.
Mechanical Properties
Minimum room-temperature values below come from the rod table of ASTM B335 for UNS N10665. Consequently, the ordered state and the section size govern final acceptance of Hastelloy B-2 forged bar.
| Condition and Grade | Tensile Strength, min. | Yield Strength (0.2%), min. | Elongation, min. |
|---|---|---|---|
| Solution Annealed — UNS N10665 | ≥760 MPa (110 ksi) | ≥350 MPa (51 ksi) | 40% |
- ASTM B335 sets one solution-annealed state for rod at these minimums, and Table 2 of that standard runs to three columns with no hardness ceiling against N10665. Besides, the size clauses stop at 88.9 mm, so heavier sections of this grade are agreed against ASTM B564. Therefore, any hardness figure a mill prints for this grade is offered as information rather than as an acceptance requirement.
Physical Properties
Handbooks place the density of this forged bar near 9.22 g/cm³ and its melting range between 1330 and 1380 °C. Moreover, the molybdenum-rich matrix leaves this forged bar non-magnetic in the annealed condition, which suits instrument and switchgear work.
Meanwhile, the physical properties table on the Hastelloy B-2 material page carries the modulus, the expansion figure and the remaining design values behind this forged bar.
Heat Treatment
No step matters more to this grade than the water-quenched anneal, because Ni4Mo precipitates between 540 and 815 °C and the corrosion resistance returns only with a rapid quench. In addition, we supply this Hastelloy B-2 forged bar in whichever state your duty calls for.
| Condition | Typical Treatment |
|---|---|
| Solution Annealed | Held at 1065–1095 °C, then water quenched, because Ni4Mo forms between 540 and 815 °C |
| Hot-Worked | Delivered as-rolled or as-forged, with the anneal agreed where the order calls for it |
| Cold-Drawn | Drawn after annealing, with the reduction recorded so the higher proof stress is documented |
| Stress-Relief Warning | A relief pass inside the 540–815 °C band precipitates Ni4Mo, so residual-stress work needs a full anneal instead |
| Post-Weld Anneal | Severe acid duty calls for a solution anneal at 1050–1100 °C and a water quench after welding |
Standards
Heavy sections of this forged bar run to ASTM B564 from ASTM International, and the Ni-Mo row of its alloy-type table carries N10665 for forgings. Moreover, ASTM B462 reaches flanges, forged fittings and valve parts of this forged bar for reducing-acid duty. Besides, ISO 9725 and DIN 17754 hold the international and European forging routes, while no aerospace specification reaches this grade in any product form.
| Standard | Product or Application |
|---|---|
| ASTM B564 / ASME SB564 | Nickel alloy forgings with N10665 in the Ni-Mo row |
| ASTM B462 / ASME SB462 | Flanges, forged fittings and valve parts |
| ISO 9725 / DIN 17754 | International and European forging routes |
Finally, the full standards list that the Hastelloy B-2 material page holds adds the plate, tube and fitting documents, the Chinese designation and the remaining product standards behind this forged bar.

Above the ASTM B335 rod ceiling every section turns into a forging order, so weight, grain direction and the test position are agreed before the ingot is cut.
Surface Finishes
Finish decides how this forged bar holds up in hydrogen chloride synthesis, absorption towers and acid regeneration loops, and most stock leaves our yard solution annealed and pickled so the reducing-acid surface arrives ready. Specifically, we agree the finish on this Hastelloy B-2 forged bar before the order leaves the desk.
| Surface Condition | Typical Use |
|---|---|
| Hot-Worked | As-rolled or as-forged skin on this forged bar, for parts that will be machined all over. |
| Rough Turned | A turned surface on this forged bar where the finishing cut stays with your shop. |
| Peeled | A machined skin on this forged bar with a uniform diameter for further turning. |
Meanwhile, the surface finishes table recorded on the Hastelloy B-2 material page lists the remaining conditions quoted for this forged bar.
