Hastelloy B-3 Threaded Rod

Hastelloy B-3 threaded rod cut from B335 bar for absorption tower tie rods and acid plant manway bolting.

Grade: Hastelloy B-3 UNS N10675 Werkstoff Nr. 2.4600 / NiMo29
Chromium Added on Purpose

ASTM B335 reaches five nickel-molybdenum numbers, and this Hastelloy B-3 threaded rod is the one that carries 1.0–3.0% chromium by design.

As-Welded Before Anything Else

Moreover, the slower precipitation in this Hastelloy B-3 threaded rod lets most joints skip the post-weld anneal the older B grade needs.

Cold-Work Limit Disclosed

Furthermore, we state the roughly 7% outer-fibre strain limit that sends this Hastelloy B-3 threaded rod back to the furnace.

PRODUCT OVERVIEW

About Hastelloy B-3 Threaded Rod

Hastelloy B-3 threaded rod arrives in UNS N10675, the nickel-molybdenum grade built for hydrochloric acid up to boiling point. Chromium between 1.0 and 3.0% slows the embrittling phase, so welded joints in this threaded rod usually enter service as welded.

We cut threaded rod from annealed B335 stock, and the threads follow the anneal rather than precede it. We supply this Hastelloy B-3 threaded rod to ASTM B335 and ASME SB335 in hot-worked, annealed and cold-drawn states, with the ASTM B564 forging route above 88.9 mm. Every consignment of this threaded rod leaves with a heat-number record, the anneal temperature actually used and a set of EN 10204 3.1 papers.

Meanwhile, the full chemistry window and the physical data behind this Hastelloy B-3 threaded rod sit on our Hastelloy B-3 material page for cross-reference.

PRODUCT FEATURES

Key Features of Hastelloy B-3 Threaded Rod

Hastelloy B-3 threaded rod arrives in UNS N10675, the nickel-molybdenum grade that carries 1.0–3.0% chromium on purpose, which slows the embrittling phase enough that most welded joints enter service without a furnace pass. We supply ASTM B335 threaded rod fully threaded in the solution-annealed condition per ASTM B335 for hydrogen chloride synthesis, acid regeneration and steel pickling hardware. Every Hastelloy B-3 threaded rod consignment travels with heat-number traceability, EN 10204 3.1 mill test reports and full export documentation.

Hastelloy B-3 Threaded Rod
Hastelloy B-3

Chromium Held on Purpose

For example, 1.0–3.0% chromium in this Hastelloy B-3 threaded rod retards the phase that embrittles the older B grade.

01

As-Welded Service

Specifically, the slower Ni3Mo kinetics mean most joints in this Hastelloy B-3 threaded rod need no post-weld anneal.

02

Hydrochloric Acid Coverage

Moreover, molybdenum at 27.0–32.0% carries this Hastelloy B-3 threaded rod through hydrochloric acid at every concentration up to boiling.

03

Oxidant-Free Duty Only

Therefore, nitric acid, ferric ion and hypochlorite rule this Hastelloy B-3 threaded rod out, so those lines belong with a chromium-rich alloy.

04

Cold-Work Limit Stated

In addition, outer-fibre strain beyond roughly 7% sends this Hastelloy B-3 threaded rod back through the anneal before welding.

05

Thick-Section Welding

Besides, an interpass ceiling of 93 °C lets multi-pass work in this Hastelloy B-3 threaded rod finish without a furnace pass.

06

No Hardness Figure Quoted

Consequently, ASTM B335 prints no hardness ceiling for this grade, so this Hastelloy B-3 threaded rod is released on chemistry and tensile results.

07

Non-Magnetic in Service

Finally, the annealed matrix keeps this Hastelloy B-3 threaded rod non-magnetic for instrument and seal work.

08

TECHNICAL INFORMATION

Technical Specifications

Detailed technical information including chemical composition, mechanical properties, standards and available dimensions.

Chemical Composition

Chromium sits deliberately between 1.0 and 3.0% in this threaded rod, and that addition is what separates the UNS N10675 window from the earlier nickel-molybdenum grades. Consequently, molybdenum holds 27.0–32.0% while carbon stops at 0.01%, so the nickel-plus-molybdenum total of this threaded rod lands between 94.0 and 98.0%.

For every element measured against its B335 limit behind this threaded rod, open the composition breakdown kept on the Hastelloy B-3 material page.

Mechanical Properties

Minimum room-temperature values below come from the rod table of ASTM B335 for UNS N10675. Consequently, the ordered state and the section size govern final acceptance of Hastelloy B-3 threaded rod.

Condition and Grade Tensile Strength, min. Yield Strength (0.2%), min. Elongation, min.
Solution Annealed — UNS N10675 ≥760 MPa (110 ksi) ≥350 MPa (51 ksi) 40%
  • ASTM B335 carries this grade inside a scope that reaches five nickel-molybdenum numbers, and its rod title means the table speaks in diameters from 7.94 mm through 88.9 mm. Besides, the hardness cell printed beside N10675 in Table 2 stands empty, so no hardness acceptance figure exists for us to quote. Consequently, work above that diameter window moves onto the ASTM B564 forging route, and we agree the test position there instead of assuming it.

Physical Properties

Reference data places the density of this threaded rod at 9.22 g/cm³, with a melting range that closes near 1418 °C. Moreover, the annealed matrix leaves this threaded rod essentially non-magnetic, and its elastic modulus settles near 216 GPa.

Meanwhile, the physical properties table on the Hastelloy B-3 material page holds the conductivity and expansion figures behind this threaded rod.

Heat Treatment

The water-quenched anneal is the specification-defining step behind this Hastelloy B-3 threaded rod, because Ni3Mo forms close to 650 °C and only a rapid quench after 1066 °C restores the corrosion resistance. Moreover, a section strained past roughly 7% at the outer fibre returns to that anneal before it can go back into a weld.

Condition Typical Treatment
Solution Annealed Held near 1066 °C (1950 °F), then water quenched, because Ni3Mo begins to form close to 650 °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 logged so the higher proof stress is documented
Cold-Work Limit Outer-fibre strain beyond roughly 7% sends the section back through the solution anneal before welding or service
Stress-Relief Caution A relief pass inside the precipitation band still embrittles this grade, so residual-stress work needs a full anneal instead
Post-Weld Anneal Most joints enter service as welded, because the slower Ni3Mo kinetics leave the as-welded zone usable

Standards

We certify the stock behind this threaded rod to ASTM B335 from ASTM International, and we cut or roll the threads after the solution anneal rather than before it. Moreover, our fastener work on this threaded rod rides on that bar certificate together with the thread class and gauging on your drawing. Besides, sizes past 88.9 mm come through the B564 forging route.

Standard Product or Application
ASTM B335 / ASME SB335 Bar document behind the stock these threads are cut on
ASTM B564 / ASME SB564 Forged bar for thread sizes above the rod ceiling
DIN 17752 / ISO 9723 German and international documents for the same melt

Finally, the full standards list on the Hastelloy B-3 material page adds the plate, tube, fitting and flange documents plus the Chinese designation behind this threaded rod.

Available sizes of this Hastelloy B-3 threaded rod depend on the route, the document, the state and the lot size. Please confirm the size, section and length you need for this threaded rod in the inquiry.

Our threaded stock of this grade is cut from bar certified to ASTM B335, and the threads are rolled or cut after the solution anneal so the work does not disturb the matrix. Moreover, the fastener specifications we work to do not name this grade, so acceptance on this threaded rod rests on the bar certificate together with the thread class and gauging on your drawing.

Surface Finishes

The surface you order decides how this threaded rod behaves once it reaches a hydrogen chloride synthesis unit, an absorption tower or an acid regeneration loop. Moreover, most stock of this threaded rod leaves the yard solution annealed and pickled. Therefore, we confirm the finish and the straightness band on this Hastelloy B-3 threaded rod before we write the offer.

Surface Condition Typical Use
Threaded Threads rolled or cut on this threaded rod after the solution anneal.
Solution Annealed and Pickled Annealing followed by acid descaling leaves this threaded rod scale-free for hydrogen chloride service.
Cold Drawn Drawn stock giving this threaded rod close diameter control with a smoother skin.

In addition, the surface finishes table recorded on the Hastelloy B-3 material page lists the remaining conditions quoted for this threaded rod.
