Alloy 59 hex bar for valve trim, instrument fittings and multi-flat components in acid duty.
Iron Held at 1.5%
ASTM B574 caps iron at 1.5% for N06059, and we release this Alloy 59 hex bar against that ceiling on every certificate.
Both Acid Families Covered
Moreover, chromium and molybdenum in this Alloy 59 hex bar carry oxidising and reducing duty in one matrix.
Cooling Route Disclosed
Furthermore, we state the quench behind this Alloy 59 hex bar, because a slow cool costs the corrosion margin.
PRODUCT OVERVIEW
About Alloy 59 Hex Bar
Alloy 59 hex 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 hex bar close to a clean solution.
The B574 chemistry and mechanics follow hex bar of this grade, and the across-flats figure comes from your drawing. We supply this Alloy 59 hex 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 hex 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 hex bar keep its passive film through an upset. The full chemistry window and the physical data behind this Alloy 59 hex bar sit on our Alloy 59 material page for cross-reference.
PRODUCT FEATURES
Key Features of Alloy 59 Hex Bar
Alloy 59 hex 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 hex bar as hot-worked, cold-drawn and ground hexagons for mixed acid plant, flue gas desulphurisation and sour service. Every Alloy 59 hex 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 hex 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 hex bar through both families.
02
Pitting Equivalent at the Top
Moreover, the lean matrix lifts the pitting resistance equivalent of this Alloy 59 hex 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 hex bar stable without a furnace pass.
04
Cold Work Sets the Strength
In addition, this Alloy 59 hex 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 hex bar on chemistry and tensile results.
06
Sour Service Listed
Consequently, NACE MR0175 lists this Alloy 59 hex 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 hex 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 hex 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 hex 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 hex bar.
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 hex bar.
| 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 hex 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 hex 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 hex bar.
Heat Treatment
The water quench is the step that defines this Alloy 59 hex 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 hex bar, issued by ASTM International. Moreover, ASME SB574 covers pressure equipment built from this hex 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 hex bar.
Dimensions
The table below lists the Alloy 59 hex 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 |
|---|---|---|
| Hex Bar | 8–70 mm across flats | Cut to length or random |
| Cold-Drawn Hex Bar | 8–50 mm across flats | Cut to length |
| Ground Hex Bar | 10–60 mm across flats | Cut to length |
| Hot-Worked Hex Bar | 20–70 mm across flats | Cut to length or random |
| Custom Across-Flats Bar | To drawing across flats | Custom |
| Custom Hex Bar | Length and corner condition to order | Custom |
ASTM B574 names hexagons inside its bar scope, so the chemistry and the mechanical minimums follow that document while the across-flats size follows your drawing. Meanwhile, we agree the corner condition and the across-flats tolerance when the order opens.
Surface Finishes
For this hex bar, the finish decides how the part feeds, seals and resists attack. Therefore, we fix the surface condition on this Alloy 59 hex bar when the order opens.
| Surface Condition | Typical Use |
|---|---|
| Cold Drawn | Drawn stock holds a close diameter on this hex bar while the drawing pass lifts proof stress. |
| Centreless Ground | Grinding holds the diameter and the straightness of this hex bar for pump spindles and valve stems. |
| Polished | A finer surface on this hex bar for product-contact and visible parts. |
In contrast, the surface finishes table on the Alloy 59 material page lists the further conditions we can quote for this hex bar.
