Request Availability →Hastelloy B-2 Hex Bar
Hastelloy B-2 hex bar for multi-flat valve internals and acid plant bolting machined from N10665 stock.
One Scope Table, One Grade
ASTM B335 carries five nickel-molybdenum grades, and every heat of this Hastelloy B-2 hex bar reads N10665.
Metallurgy Held to the Window
Moreover, molybdenum at 26.0–30.0% with chromium below 1% keeps this Hastelloy B-2 hex bar identical in analysis to the grade already installed.
Spares Without a Grade Review
Furthermore, a one-to-one replacement in this Hastelloy B-2 hex bar needs no re-rating of the vessel or the piping it serves.
PRODUCT OVERVIEW
About Hastelloy B-2 Hex Bar
Hastelloy B-2 hex 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 hex bar.
Hex bar ships against B335 chemistry and mechanics, with the across-flats size fixed at order entry. Each consignment of this Hastelloy B-2 hex 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 hex 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 hex bar for cross-reference.
PRODUCT FEATURES
Key Features of Hastelloy B-2 Hex Bar
Hastelloy B-2 hex 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 hex bar cold drawn to the across-flats size, annealed where the order calls for it for hydrogen chloride synthesis, steel pickling lines and acid regeneration hardware. Every Hastelloy B-2 hex 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 hex bar serve acid at every concentration up to boiling.
01
One-to-One Replacement
Specifically, a spare in this Hastelloy B-2 hex 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 hex 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 hex bar, so proof stress above the annealed floor comes from drawing alone.
04
Quench-Controlled Anneal
Besides, we hold this Hastelloy B-2 hex 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 hex 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 hex 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 hex 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 hex 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 hex 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 hex bar near 9.22 g/cm³ and its melting range between 1330 and 1380 °C. Moreover, the molybdenum-rich matrix leaves this hex 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 hex 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 hex 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
ASTM B335 is the principal rod document for this hex bar, issued by ASTM International, and its scope table lists N10665 alongside four other nickel-molybdenum grades. Moreover, the size clauses of that standard stop at 88.9 mm, so heavier sections of this hex bar move across to the forging document. Besides, DIN 17752 and ISO 9723 carry the German and international bar routes for this grade.
| Standard | Product or Application |
|---|---|
| ASTM B335 / ASME SB335 | Nickel-molybdenum alloy rod, 7.94–88.9 mm, UNS N10665 in the scope table |
| DIN 17752 / ISO 9723 | German and international bar documents |
| ASTM B564 / ASME SB564 | Forged bar and heavier sections above the rod size ceiling |
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 hex bar.

Surface Finishes
Finish decides how this hex 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 hex bar before the order leaves the desk.
| Surface Condition | Typical Use |
|---|---|
| Cold Drawn | Drawn stock giving this hex bar close diameter control and a smoother skin. |
| Solution Annealed and Pickled | Annealing followed by acid descaling leaves this hex bar scale-free for hydrochloric acid service. |
| Centreless Ground | Ground diameter and straightness on this hex bar for pump spindles and metering plungers. |
Meanwhile, the surface finishes table recorded on the Hastelloy B-2 material page lists the remaining conditions quoted for this hex bar.

FAQ
Frequently Asked Questions
Which standard covers this Hastelloy B-2 hex bar?
ASTM B335 and ASME SB335 govern this Hastelloy B-2 hex bar, and the scope of that standard lists N10665 alongside four other nickel-molybdenum grades.
Is this Hastelloy B-2 hex bar suitable for hydrochloric acid duty?
Yes. Molybdenum at 26.0–30.0% carries this Hastelloy B-2 hex bar through hydrochloric acid at every concentration up to boiling, provided the stream carries no oxidant.
Which contaminants rule this Hastelloy B-2 hex bar out?
Ferric ions, cupric ions, nitric acid and hypochlorite. Each one oxidises the surface of this Hastelloy B-2 hex bar, so those duties belong with a chromium-bearing alloy.
Does this Hastelloy B-2 hex bar qualify for sour service?
No. We do not release this Hastelloy B-2 hex bar against NACE MR0175, because an H2S-bearing stream can form low-melting nickel sulfide on a high-nickel surface.
