PRODUCT OVERVIEW
About Hastelloy C-22 Round Bar
Hastelloy C-22 round bar arrives in UNS N06022, the nickel-chromium-molybdenum-tungsten grade that holds nitric acid, ferric chloride and wet chlorine at bay. Cupric chloride etch baths, chlorine dioxide bleach liquor and chloride-bearing flue gas also sit inside the envelope of this round bar.
Bar stock of this grade runs to ASTM B574 and ASME SB574 in hot-worked, solution-annealed and cold-drawn states. Each order for this Hastelloy C-22 round bar ships with heat-number records, a solution-anneal record and EN 10204 3.1 paperwork for goods-in checks. Besides, we agree the anneal record and the finish on the round bar before we book a heat of UNS N06022.
Meanwhile, the Hastelloy C-22 material page holds the chemistry and the sour-service data behind this Hastelloy C-22 round bar for cross-reference.
PRODUCT FEATURES
Key Features of Hastelloy C-22 Round Bar
Hastelloy C-22 round bar arrives in UNS N06022, the chromium-rich nickel-chromium-molybdenum-tungsten grade whose chromium above 20% carries nitric acid and wet chlorine while molybdenum and tungsten hold reducing acids in check. We supply ASTM B574 round bar in hot-worked, solution-annealed and cold-drawn states, cut to length for pharmaceutical reactors, pickling lines and flue-gas desulfurisation hardware. Every Hastelloy C-22 round bar consignment travels with heat-number traceability, EN 10204 3.1 mill test reports and full export documentation.
Hastelloy C-22
Nitric Acid Resistance
For example, chromium above 20% in this Hastelloy C-22 round bar holds nitric acid duty that a lower-chromium grade cannot take.
01
Ferric and Cupric Chloride Duty
Specifically, oxidising chloride salts leave this Hastelloy C-22 round bar unaffected on wetted surfaces.
02
Wet Chlorine Capability
Moreover, this Hastelloy C-22 round bar serves moist chlorine and chlorine dioxide streams without a lining.
03
NACE MR0175 Qualification
Besides, sour-service release for this Hastelloy C-22 round bar follows NACE MR0175 / ISO 15156 with hardness recorded per lot.
04
Ultra-Low Carbon Weld Zones
In addition, carbon at 0.015% max and silicon at 0.08% max leave no carbides in this Hastelloy C-22 round bar to precipitate.
05
Pitting Resistance Near 70
Therefore, a pitting resistance equivalent number close to 70 keeps chloride attack off this Hastelloy C-22 round bar.
06
Cold-Work Strength
Consequently, drawing raises the proof stress of this Hastelloy C-22 round bar above the annealed floor where shafts need it.
07
Non-Magnetic Behaviour
Finally, instrument assemblies sit comfortably with this Hastelloy C-22 round bar because the grade stays practically non-magnetic at ambient temperature.
08

TECHNICAL INFORMATION
Technical Specifications
Detailed technical information including chemical composition, mechanical properties, standards and available dimensions.
Chemical Composition
ASTM B574 sets chromium between 20.0% and 22.5% in this round bar, roughly six points above the C-276 window, while molybdenum at 12.5–14.5% and tungsten at 2.5–3.5% carry the reducing side of the same duty. Besides, carbon at 0.015% maximum and silicon at 0.08% maximum keep carbides out of the grain boundaries of this round bar, so a welded joint holds its corrosion resistance without a post-weld anneal.
For the full element-by-element limits behind this round bar, open the composition breakdown recorded on the Hastelloy C-22 material page.
Mechanical Properties
Minimum room-temperature values below come from the rod and bar table of ASTM B574 for UNS N06022. Consequently, the ordered state and the hardness basis govern final acceptance of Hastelloy C-22 round bar.
| Condition and Grade | Tensile Strength, min. | Yield Strength (0.2%), min. | Elongation, min. |
|---|---|---|---|
| Solution Annealed — UNS N06022 | ≥690 MPa (100 ksi) | ≥310 MPa (45 ksi) | 45% |
- ASTM B574 sets one solution-annealed state for rod and bar at these minimums, and its mechanical table runs to three columns with no hardness limit at all. Besides, the as-cold-finished clause of that standard reaches other grades in its scope list rather than N06022, so drawn and ground bar of this grade is agreed at quotation. Therefore, sour-service orders carry a per-lot hardness record measured against the 35 HRC ceiling, and no mill hardness maximum is printed on the release.
Physical Properties
Data sheets put the density of this round bar near 8.69 g/cm³ and its melting range between 1357 and 1399 °C. Moreover, the pitting resistance equivalent number of this round bar sits close to 70, which is what keeps chloride pitting off wetted surfaces. Besides, the nickel-rich matrix leaves this round bar practically non-magnetic at ambient temperature.
Meanwhile, the physical properties table on the Hastelloy C-22 material page carries the modulus, the expansion figure and the remaining design values behind this round bar.
Heat Treatment
No step matters more to this grade than the water-quenched anneal, because the corrosion resistance the media demand comes back only with a rapid quench straight after 1121 °C. In addition, we supply this Hastelloy C-22 round bar in whichever state your duty calls for.
| Condition | Typical Treatment |
|---|---|
| Solution Annealed | Held at 1121 °C, then water quenched, because slow cooling would let intermetallic phases form |
| 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 recorded so the higher proof stress is documented |
| Stress-Relief Warning | A conventional 650 °C relief cycle destroys the corrosion resistance of this grade, so residual-stress work needs a full anneal instead |
| Sour-Service Release | NACE MR0175 orders carry a per-lot hardness record against the 35 HRC ceiling |
Standards
ASTM B574 is the primary rod and bar document for this round bar, issued by ASTM International, and its scope table carries a family of low-carbon nickel-chromium-molybdenum grades with N06022 among them. Moreover, ASME SB574 takes over wherever equipment falls under pressure-code jurisdiction. Besides, DIN 17752, ISO 9723 and VdTÜV Werkstoffblatt 479 serve the European and international routes.
| Standard | Product or Application |
|---|---|
| ASTM B574 / ASME SB574 | Nickel-chromium-molybdenum-tungsten rod and bar, UNS N06022 in the scope table |
| DIN 17752 / ISO 9723 | German and international bar documents |
| VdTÜV 479 / NACE MR0175 | German material sheet and sour-service qualification |
Finally, the full standards list that the Hastelloy C-22 material page holds adds the pressure documents, the European designations and the other product documents behind this round bar.

Surface Finishes
Surface condition decides how this round bar performs in nitric acid trains, ferric chloride pickling lines and pharmaceutical reactors, and most stock leaves our yard solution annealed and pickled so it arrives ready for oxidising duty. Specifically, we settle the finish on this Hastelloy C-22 round bar before the order leaves the desk.
| Surface Condition | Typical Use |
|---|---|
| Solution Annealed and Pickled | Annealing followed by acid descaling leaves this round bar scale-free for nitric and ferric chloride duty. |
| Peeled | A machined skin on this round bar with a uniform diameter for oxidising-acid shaft work. |
| Descaled and Ground | A uniform descaled surface on this round bar for inspection and coating work. |
Meanwhile, the surface finishes table recorded on the Hastelloy C-22 material page lists the remaining conditions quoted for this round bar.
