PRODUCT OVERVIEW
About Hastelloy C-22 Forged Bar
Hastelloy C-22 forged 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 forged bar.
Forged bar follows ASTM B564 rather than B574, and we agree the reduction ratio before cutting the ingot. Each order for this Hastelloy C-22 forged 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 forged 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 forged bar for cross-reference.
PRODUCT FEATURES
Key Features of Hastelloy C-22 Forged Bar
Hastelloy C-22 forged 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 forged bar in forged, rough-turned and solution-annealed states for pharmaceutical reactors, pickling lines and flue-gas desulfurisation hardware. Every Hastelloy C-22 forged 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 forged 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 forged bar unaffected on wetted surfaces.
02
Wet Chlorine Capability
Moreover, this Hastelloy C-22 forged bar serves moist chlorine and chlorine dioxide streams without a lining.
03
NACE MR0175 Qualification
Besides, sour-service release for this Hastelloy C-22 forged 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 forged 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 forged bar.
06
Cold-Work Strength
Consequently, drawing raises the proof stress of this Hastelloy C-22 forged bar above the annealed floor where shafts need it.
07
Non-Magnetic Behaviour
Finally, instrument assemblies sit comfortably with this Hastelloy C-22 forged 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 forged 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 forged bar, so a welded joint holds its corrosion resistance without a post-weld anneal.
For the full element-by-element limits behind this forged 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 forged 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 forged bar near 8.69 g/cm³ and its melting range between 1357 and 1399 °C. Moreover, the pitting resistance equivalent number of this forged bar sits close to 70, which is what keeps chloride pitting off wetted surfaces. Besides, the nickel-rich matrix leaves this forged 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 forged 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 forged 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
Orders for heavy sections of this forged bar run to ASTM B564 from ASTM International, and the UNS table of that document carries N06022 for forgings. Moreover, ASTM B462 reaches flanges, forged fittings and valve parts of this forged bar for corrosive duty. Besides, ISO 9725 and DIN 17754 hold the international and European forging routes, while the grade carries no aerospace AMS document in any form.
| Standard | Product or Application |
|---|---|
| ASTM B564 / ASME SB564 | Nickel alloy forgings with UNS N06022 listed |
| ASTM B462 / ASME SB462 | Flanges, forged fittings and valve parts |
| ISO 9725 / DIN 17754 | International and European forging routes |
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 forged bar.
Dimensions
Dimensions of Hastelloy C-22 forged bar follow the route, the document and the order quantity. Therefore, typical supply ranges sit in the table below, so please confirm your sizes in the inquiry.
| Product Form | Typical Supply | Length |
|---|---|---|
| Forged Round Bar | 100–600 mm dia. | Cut to length |
| Forged Square Bar | 100–300 mm | Cut to length |
| Forged Flat Bar | 20–150 mm thick × 50–400 mm wide | Cut to length |
| Rough-Turned Forged Bar | 100–600 mm dia. | Cut to length |
| Solution-Annealed Forged Bar | 100–600 mm dia. | Cut to length |
| Forging Stock | 100–500 mm sections | Custom |
| Custom Forged Section | To drawing | Custom |
Available sizes of this Hastelloy C-22 forged bar depend on the route, the document, the state and the lot size. Please confirm the size, section and length you need for this forged bar in the inquiry.
Forged sections of this grade are quoted to ASTM B564, whose UNS table lists N06022 for forgings, alongside B462 for flanges, forged fittings and valve parts. Moreover, ISO 9725 and DIN 17754 carry the international and European forging routes, and sour-service forgings add hardness records to the release papers of this Hastelloy C-22 forged bar.
Surface Finishes
Surface condition decides how this forged 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 forged bar before the order leaves the desk.
| Surface Condition | Typical Use |
|---|---|
| Hot-Worked | As-rolled or as-forged skin on this forged bar, for parts that will be machined all over. |
| Rough Turned | A turned surface on this forged bar where the finishing cut stays with your shop. |
| Solution Annealed and Pickled | Annealing followed by acid descaling leaves this forged bar scale-free for nitric and ferric chloride duty. |
Meanwhile, the surface finishes table recorded on the Hastelloy C-22 material page lists the remaining conditions quoted for this forged bar.
