PRODUCT OVERVIEW
About Hastelloy C-22 Threaded Rod
Hastelloy C-22 threaded rod 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 threaded rod.
Threaded rod follows ASTM F468 for nonferrous fasteners, and we fix the thread class at order entry. Each order for this Hastelloy C-22 threaded rod 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 threaded rod 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 threaded rod for cross-reference.
PRODUCT FEATURES
Key Features of Hastelloy C-22 Threaded Rod
Hastelloy C-22 threaded rod 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 threaded rod fully threaded in the solution-annealed state per ASTM B574 for pharmaceutical reactors, pickling lines and flue-gas desulfurisation hardware. Every Hastelloy C-22 threaded rod 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 threaded rod 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 threaded rod unaffected on wetted surfaces.
02
Wet Chlorine Capability
Moreover, this Hastelloy C-22 threaded rod serves moist chlorine and chlorine dioxide streams without a lining.
03
NACE MR0175 Qualification
Besides, sour-service release for this Hastelloy C-22 threaded rod 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 threaded rod to precipitate.
05
Pitting Resistance Near 70
Therefore, a pitting resistance equivalent number close to 70 keeps chloride attack off this Hastelloy C-22 threaded rod.
06
Cold-Work Strength
Consequently, drawing raises the proof stress of this Hastelloy C-22 threaded rod above the annealed floor where shafts need it.
07
Non-Magnetic Behaviour
Finally, instrument assemblies sit comfortably with this Hastelloy C-22 threaded rod 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 threaded rod, 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 threaded rod, so a welded joint holds its corrosion resistance without a post-weld anneal.
For the full element-by-element limits behind this threaded rod, 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 threaded rod.
| 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 threaded rod near 8.69 g/cm³ and its melting range between 1357 and 1399 °C. Moreover, the pitting resistance equivalent number of this threaded rod sits close to 70, which is what keeps chloride pitting off wetted surfaces. Besides, the nickel-rich matrix leaves this threaded rod 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 threaded rod.
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 threaded rod 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
Bar stock behind this threaded rod carries ASTM B574 certification from ASTM International. Moreover, ASTM F468 covers nonferrous bolts, hex cap screws, socket head cap screws and studs, and ASTM B462 reaches valve and flange parts of this threaded rod. Besides, sour-service orders add NACE MR0175 / ISO 15156, where this grade sits in the solution-annealed condition at 35 HRC maximum and in the cold-worked condition at 40 HRC maximum.
| Standard | Product or Application |
|---|---|
| ASTM B574 | Bar stock behind this threaded product |
| ASTM F468 / ASTM B462 | Bolts, hex cap screws and studs, plus valve and flange parts |
| NACE MR0175 / ISO 15156 | Sour-service qualification at 35 HRC in the annealed state |
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 threaded rod.
Dimensions
Dimensions of Hastelloy C-22 threaded rod 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 |
|---|---|---|
| Threaded Rod | 6–64 mm dia., UNC and UNF | 1 m, 2 m, 3 m or custom |
| Metric Threaded Rod | M6–M64 | 1 m, 2 m, 3 m or custom |
| Full-Thread Studs | 6–64 mm dia. | Cut to length |
| Double-Ended Studs | M8–M36 | Cut to length |
| NACE-Documented Threaded Rod | 6–64 mm dia. | Cut to length |
| Custom Threaded Rod | To drawing | Custom |
Available sizes of this Hastelloy C-22 threaded rod depend on the route, the document, the state and the lot size. Please confirm the size, section and length you need for this threaded rod in the inquiry.
Bar stock behind this product carries ASTM B574 certification, and ASTM F468 covers nonferrous bolts, hex cap screws, socket head cap screws and studs. Moreover, sour-service orders add NACE MR0175 / ISO 15156, where this grade appears in the solution-annealed state at 35 HRC maximum and in the cold-worked state at 40 HRC maximum. Therefore, we record hardness per lot and confirm the applicable state before release.
Surface Finishes
Surface condition decides how this threaded rod 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 threaded rod before the order leaves the desk.
| Surface Condition | Typical Use |
|---|---|
| Cold Drawn | Drawn stock giving this threaded rod close diameter control and a smooth bright skin. |
| Rough Turned | A turned surface on this threaded rod where the finishing cut stays with your shop. |
| Solution Annealed and Pickled | Annealing followed by acid descaling leaves this threaded rod 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 threaded rod.
