Alloy 59 threaded rod and stud bolts to the ASTM F468 nickel-chromium-molybdenum grade chain.
Iron Held at 1.5%
ASTM B574 caps iron at 1.5% for N06059, and we release this Alloy 59 threaded rod against that ceiling on every certificate.
Both Acid Families Covered
Moreover, chromium and molybdenum in this Alloy 59 threaded rod carry oxidising and reducing duty in one matrix.
Cooling Route Disclosed
Furthermore, we state the quench behind this Alloy 59 threaded rod, because a slow cool costs the corrosion margin.
PRODUCT OVERVIEW
About Alloy 59 Threaded Rod
Alloy 59 threaded rod arrives in UNS N06059, the low-iron nickel-chromium-molybdenum grade for mixed acid duty. Iron and silicon at 1.5% and 0.10% maximum hold this Alloy 59 threaded rod close to a clean solution.
We roll or cut threads onto solution-annealed B574 stock, so the anneal always precedes the thread. We supply this Alloy 59 threaded rod to ASTM B574 and ASME SB574 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 and quench route actually used and a set of EN 10204 3.1 papers.
Meanwhile, that lean matrix is what lets this Alloy 59 threaded rod keep its passive film through an upset. The full chemistry window and the physical data behind this Alloy 59 threaded rod sit on our Alloy 59 material page for cross-reference.
PRODUCT FEATURES
Key Features of Alloy 59 Threaded Rod
Alloy 59 threaded rod arrives in UNS N06059, the low-iron nickel-chromium-molybdenum grade that holds iron to 1.5% and silicon to 0.10%, so one matrix covers both acid families. We supply ASTM B574 threaded rod as rolled or cut threads on solution-annealed stock for mixed acid plant, flue gas desulphurisation and sour service. Every Alloy 59 threaded rod consignment travels with heat-number traceability, EN 10204 3.1 mill test reports and full export documentation.
Alloy 59
Iron at the Floor
For example, 1.5% iron in this Alloy 59 threaded rod is a quarter of the ceiling C-276 allows, which steadies the passive film.
01
Two Acid Families at Once
Specifically, chromium at 22.0–24.0% and molybdenum at 15.0–16.5% carry this Alloy 59 threaded rod through both families.
02
Pitting Equivalent at the Top
Moreover, the lean matrix lifts the pitting resistance equivalent of this Alloy 59 threaded rod to the head of the wrought nickel family.
03
Silicon and Carbon Held Low
Therefore, silicon at 0.10% and carbon at 0.010% keep the weld zone of this Alloy 59 threaded rod stable without a furnace pass.
04
Cold Work Sets the Strength
In addition, this Alloy 59 threaded rod takes nothing from aging, so drawing is the only route above the annealed floor.
05
No Hardness Figure Quoted
Besides, ASTM B574 prints no hardness ceiling for this grade, so we release this Alloy 59 threaded rod on chemistry and tensile results.
06
Sour Service Listed
Consequently, NACE MR0175 lists this Alloy 59 threaded rod at the condition the standard sets rather than at an invented figure.
07
Non-Magnetic in Service
Finally, the annealed matrix keeps this Alloy 59 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
ASTM B574 fixes the UNS N06059 window that governs this threaded rod, holding iron to 1.5% maximum and capping silicon at 0.10%. In addition, chromium runs between 22.0% and 24.0% in this threaded rod, while molybdenum sits between 15.0% and 16.5%.
Meanwhile, the full composition table on the Alloy 59 material page sets every element against its ASTM B574 limit for this threaded rod.
Mechanical Properties
The floors in the table below come from the ASTM B574 bar table for UNS N06059. Therefore, the ordered condition and the ruling section settle final acceptance of Alloy 59 threaded rod.
| Condition and Grade | Tensile Strength, min. | Yield Strength (0.2%), min. | Elongation, min. |
|---|---|---|---|
| Solution Annealed — UNS N06059 | ≥690 MPa (100 ksi) | ≥310 MPa (45 ksi) | 45% |
- ASTM B574 carries three columns in Table 5 and prints no hardness requirement against N06059, so release rests on chemistry and tensile results rather than on an indenter reading. Besides, the title of that document limits it to rod and bar, and clause 1.2 stops the bar route at 88.9 mm. Therefore, work above that diameter moves onto the ASTM B564 forging route, where we agree the test position instead of assuming it.
Physical Properties
Published references place the density of this threaded rod near 8.6 g/cm³ and its melting range at 1310–1360 °C. Moreover, an elastic modulus close to 210 GPa and a relative permeability of 1.001 maximum keep this threaded rod effectively non-magnetic in service.
Therefore, the physical properties table on the Alloy 59 material page carries the conductivity, the resistivity and the remaining design values behind this threaded rod.
Heat Treatment
The water quench is the step that defines this Alloy 59 threaded rod, because the section has to fall from the anneal to about 500 °C faster than 150 °C per minute. Moreover, a section deformed beyond 15% returns to that anneal before it enters service.
| Condition | Typical Treatment |
|---|---|
| Solution Annealed | Held between 1100 °C and 1180 °C and water quenched, with about 1120 °C the preferred figure |
| Cooling Rate | Better than 150 °C per minute from the anneal down to about 500 °C, or grain-boundary phases form |
| Hot-Worked | Forged or rolled between 1180 °C and 950 °C, with heavy reduction taken at the top of that band |
| Cold-Drawn | Drawn after the anneal, in one of the three graded strength levels that Table 3 defines |
| Cold-Forming Limit | Deformation beyond 15% sends the section back through the final solution anneal before service |
| Stress-Relief Caution | A relief pass inside the precipitation band still costs corrosion resistance, so the alternative is settled before it is booked |
| Post-Weld Anneal | Most joints enter service as welded, because the low carbon and silicon levels keep the weld zone stable |
Standards
ASTM F468 carries the nickel-chromium-molybdenum fastener grades for this threaded rod, reaching Grade 1 through Grade 4 on its Ni 59 line, issued by ASTM International. Moreover, ASTM F467 covers the nuts that match those grades of this threaded rod.
| Standard | Product or Application |
|---|---|
| ASTM F468 / ASME SF468 | Bolts, cap screws, socket screws and studs, Ni 59 Grade 1 to 4 |
| ASTM F467 / ASME SF467 | Nuts matching the F468 fastener grades |
| ASTM B574 / ASME SB574 | Solution-annealed bar stock behind the thread |
Beyond that, the standards table on the Alloy 59 material page carries the European designations, the tubular documents and the flat-product call-outs for this threaded rod.
Dimensions
The table below lists the Alloy 59 threaded rod sizes we ship most often, while the route, the document and the lot size decide what else is possible. Please confirm your own size, section and length with the inquiry.
| Product Form | Typical Supply | Length |
|---|---|---|
| Grade 1 Threaded Rod | 827 MPa (120 ksi) tensile min., 586 MPa (85 ksi) yield min. | M6–M36, cut to length |
| Grade 2 Threaded Rod | 931 MPa (135 ksi) tensile min., 862 MPa (125 ksi) yield min. | M6–M36, cut to length |
| Grade 3 Threaded Rod | 1103 MPa (160 ksi) tensile min., 1034 MPa (150 ksi) yield min. | M6–M30, cut to length |
| Stud Bolts | Threaded at both ends to the drawing | Cut to length |
| U-Bolts and Tie Rods | Formed from solution-annealed stock | Cut to length |
| Custom Threaded Rod | Class, pitch and length fixed with you | Custom |
The fastener chain is real for this grade, because the F468 grade table carries Ni 59 in four strength levels rather than treating the alloy as a one-off. Moreover, the threads roll or cut after the solution anneal, so the strength class and the stock condition stay consistent from lot to lot.
Surface Finishes
For this threaded rod, the finish decides how the part feeds, seals and resists attack. Therefore, we fix the surface condition on this Alloy 59 threaded rod when the order opens.
| Surface Condition | Typical Use |
|---|---|
| Threaded | Rolled or cut threads follow the solution anneal on this threaded rod. |
| Solution Annealed and Pickled | The anneal followed by acid descaling leaves this threaded rod scale-free for mixed acid and chloride duty. |
| Cold Drawn | Drawn stock holds a close diameter on this threaded rod while the drawing pass lifts proof stress. |
In contrast, the surface finishes table on the Alloy 59 material page lists the further conditions we can quote for this threaded rod.
