Open-die forged Alloy 59 bar for valve bodies, tube sheets and heavy rings above the bar window.
Iron Held at 1.5%
ASTM B574 caps iron at 1.5% for N06059, and we release this Alloy 59 forged bar against that ceiling on every certificate.
Both Acid Families Covered
Moreover, chromium and molybdenum in this Alloy 59 forged bar carry oxidising and reducing duty in one matrix.
Cooling Route Disclosed
Furthermore, we state the quench behind this Alloy 59 forged bar, because a slow cool costs the corrosion margin.
PRODUCT OVERVIEW
About Alloy 59 Forged Bar
Alloy 59 forged 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 forged bar close to a clean solution.
We forge and test sections above the B574 bar window to ASTM B564, with the cooling route agreed in advance. We supply this Alloy 59 forged 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 forged 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 forged bar keep its passive film through an upset. The full chemistry window and the physical data behind this Alloy 59 forged bar sit on our Alloy 59 material page for cross-reference.
PRODUCT FEATURES
Key Features of Alloy 59 Forged Bar
Alloy 59 forged 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 forged bar as open-die forged sections, solution annealed and quenched for mixed acid plant, flue gas desulphurisation and sour service. Every Alloy 59 forged 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 forged 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 forged bar through both families.
02
Pitting Equivalent at the Top
Moreover, the lean matrix lifts the pitting resistance equivalent of this Alloy 59 forged 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 forged bar stable without a furnace pass.
04
Cold Work Sets the Strength
In addition, this Alloy 59 forged 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 forged bar on chemistry and tensile results.
06
Sour Service Listed
Consequently, NACE MR0175 lists this Alloy 59 forged 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 forged 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 forged 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 forged 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 forged 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 forged 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 B564 prints the same tensile floor for this grade as the bar document does, so the weight of the forging never changes the acceptance figures. In addition, that document fixes the cooling rule at better than 150 °C per minute from the anneal down to about 500 °C. Therefore, we agree the cooling route along with the test position before the press opens.
Physical Properties
Published references place the density of this forged 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 forged 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 forged bar.
Heat Treatment
The water quench is the step that defines this Alloy 59 forged 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 B564 is the forging document behind this forged bar, and its nickel-chromium-molybdenum row names N06059, issued by ASTM International. In addition, ASTM B462 covers flanges and forged fittings produced from this forged bar.
| Standard | Product or Application |
|---|---|
| ASTM B564 / ASME SB564 | Nickel alloy forgings, with N06059 in the Ni-Cr-Mo row |
| ASTM B462 / ASME SB462 | Forged or rolled flanges and forged fittings |
| ASTM B472 | Forging billets and bars for reforging |
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 forged bar.
Dimensions
The table below lists the Alloy 59 forged 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 |
|---|---|---|
| Forged Bar | 200–1000 mm dia. | As forged or cut to length |
| Open-Die Forged Bar | Heavy sections to drawing | As forged |
| Forged Ring | Rolled or expanded rings to drawing | As forged |
| Forged Disc | Discs cut from a forged blank | As forged |
| Tube Sheet Blank | Blanks tested before the holes are drilled | As forged |
| Custom Forged Bar | To drawing, with test position agreed | Custom |
ASTM B564 fixes a cooling rule rather than a strength rule, because the section must fall from the anneal to about 500 °C faster than 150 °C per minute. Consequently, we quote thick sections with that cooling route agreed in advance instead of pricing them from a weight table alone.
Surface Finishes
For this forged bar, the finish decides how the part feeds, seals and resists attack. Therefore, we fix the surface condition on this Alloy 59 forged bar when the order opens.
| Surface Condition | Typical Use |
|---|---|
| Hot-Worked | Hot-worked stock of this forged bar arrives with its rolling or forging skin intact. |
| Rough Turned | Turning removes the scale from this forged bar while the finishing cut stays with your shop. |
| Solution Annealed and Pickled | The anneal followed by acid descaling leaves this forged bar scale-free for mixed acid and chloride duty. |
In contrast, the surface finishes table on the Alloy 59 material page lists the further conditions we can quote for this forged bar.
