Cold-drawn Alloy 59 bar carrying the three graded strength levels of ASTM B574 Table 3.
Iron Held at 1.5%
ASTM B574 caps iron at 1.5% for N06059, and we release this Alloy 59 cold-drawn bar against that ceiling on every certificate.
Both Acid Families Covered
Moreover, chromium and molybdenum in this Alloy 59 cold-drawn bar carry oxidising and reducing duty in one matrix.
Cooling Route Disclosed
Furthermore, we state the quench behind this Alloy 59 cold-drawn bar, because a slow cool costs the corrosion margin.
PRODUCT OVERVIEW
About Alloy 59 Cold-Drawn Bar
Alloy 59 cold-drawn bar 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 cold-drawn bar close to a clean solution.
Clause 1.2.3 of B574 opens a graded cold-worked line for this grade, and the three levels reach 1103 MPa tensile. We supply this Alloy 59 cold-drawn bar 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 cold-drawn bar 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 cold-drawn bar keep its passive film through an upset. The full chemistry window and the physical data behind this Alloy 59 cold-drawn bar sit on our Alloy 59 material page for cross-reference.
PRODUCT FEATURES
Key Features of Alloy 59 Cold-Drawn Bar
Alloy 59 cold-drawn bar 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 cold-drawn bar as cold-worked stock in three ordered strength grades for mixed acid plant, flue gas desulphurisation and sour service. Every Alloy 59 cold-drawn bar 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 cold-drawn bar 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 cold-drawn bar through both families.
02
Pitting Equivalent at the Top
Moreover, the lean matrix lifts the pitting resistance equivalent of this Alloy 59 cold-drawn bar 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 cold-drawn bar stable without a furnace pass.
04
Cold Work Sets the Strength
In addition, this Alloy 59 cold-drawn bar 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 cold-drawn bar on chemistry and tensile results.
06
Sour Service Listed
Consequently, NACE MR0175 lists this Alloy 59 cold-drawn bar 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 cold-drawn bar 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 cold-drawn bar, holding iron to 1.5% maximum and capping silicon at 0.10%. In addition, chromium runs between 22.0% and 24.0% in this cold-drawn bar, 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 cold-drawn bar.
Mechanical Properties
Three graded strength levels apply to cold-worked stock of this grade, and the figures below come from the cold-finished table of ASTM B574. Consequently, the ordered grade and the section size govern final acceptance of Alloy 59 cold-drawn bar.
| Cold-Worked Grade (ASTM B574 Table 3) | Tensile Strength, min. | Yield Strength (0.2%), min. | Elongation, min. |
|---|---|---|---|
| Grade 1 | ≥827 MPa (120 ksi) | ≥586 MPa (85 ksi) | 20% |
| Grade 2 | ≥931 MPa (135 ksi) | ≥862 MPa (125 ksi) | 20% |
| Grade 3 | ≥1103 MPa (160 ksi) | ≥1034 MPa (150 ksi) | 15% |
- Clause 1.2.3 of ASTM B574 opens this cold-worked route between 6.35 and 88.9 mm, and it reaches only four UNS numbers, of which N06059 is one. Moreover, Table 2 sets the diameter tolerance at ±0.25 mm with 0.25 mm roundness across the 19.05–88.9 mm band, which is tighter than the band the annealed route carries. Consequently, the grade and the ruling diameter belong together on the enquiry.
Physical Properties
Published references place the density of this cold-drawn bar 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 cold-drawn bar 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 cold-drawn bar.
Heat Treatment
The water quench is the step that defines this Alloy 59 cold-drawn bar, 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 B574 is the principal UNS N06059 rod and bar document for this cold-drawn bar, issued by ASTM International. Moreover, ASME SB574 covers pressure equipment built from this cold-drawn bar while ASTM B564 takes over above 88.9 mm.
| Standard | Product or Application |
|---|---|
| ASTM B574 / ASME SB574 | Nickel-chromium-molybdenum rod and bar, solution annealed |
| ASTM B564 / ASME SB564 | Forgings and forging stock above the bar window |
| NACE MR0175 / ISO 15156 | Sour service, listed at the highest test level |
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 cold-drawn bar.
Dimensions
The table below lists the Alloy 59 cold-drawn bar 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 Cold-Drawn Bar | 827 MPa (120 ksi) tensile min., 586 MPa (85 ksi) yield min. | 6.35–88.9 mm dia. |
| Grade 2 Cold-Drawn Bar | 931 MPa (135 ksi) tensile min., 862 MPa (125 ksi) yield min. | 6.35–88.9 mm dia. |
| Grade 3 Cold-Drawn Bar | 1103 MPa (160 ksi) tensile min., 1034 MPa (150 ksi) yield min. | 6.35–88.9 mm dia. |
| Ground Cold-Drawn Bar | Any grade, ground to the tight band of Table 2 | 6.35–88.9 mm dia. |
| Turned Cold-Drawn Bar | Any grade, turned to a uniform diameter | 6.35–88.9 mm dia. |
| Custom Cold-Drawn Bar | Reduction and grade fixed to your drawing | Custom |
Clause 1.2.3 of ASTM B574 reaches this grade only between 6.35 and 88.9 mm, and it is the reason a strength grade can be ordered by name rather than agreed case by case. Therefore, name the grade and the ruling diameter together on the enquiry.
Surface Finishes
For this cold-drawn bar, the finish decides how the part feeds, seals and resists attack. Therefore, we fix the surface condition on this Alloy 59 cold-drawn bar when the order opens.
| Surface Condition | Typical Use |
|---|---|
| Cold Drawn | Drawn stock holds a close diameter on this cold-drawn bar while the drawing pass lifts proof stress. |
| Centreless Ground | Grinding holds the diameter and the straightness of this cold-drawn bar for pump spindles and valve stems. |
| Peeled | A machined skin gives this cold-drawn bar an even diameter ahead of the finishing cut. |
In contrast, the surface finishes table on the Alloy 59 material page lists the further conditions we can quote for this cold-drawn bar.
