Hastelloy C-22 Hot-Rolled Plate
Solution-annealed plate from 4.8 mm up for vessel shells, scrubber liners, and ducting.
Request Availability →UNS N06022 flat product to B575 — hot-rolled plate, cold-rolled sheet, and strip for vessels and scrubbers.
Plate, sheet, and strip between 0.5 mm and 100 mm sit under a single UNS N06022 purchase route.
In addition, chromium above 20% lets one lining serve a vessel whose process chemistry swings both ways.
Besides, cutting lines profile, shear, or saw plate to the geometry your fabricators draw.
Hastelloy C-22 Plate and Sheet supplies UNS N06022 flat product for vessel shells, ducting, and scrubber liners. Chromium above 20% carries oxidizing media, while molybdenum and tungsten hold the reducing side. Flat-rolled gauges follow ASTM B575 alongside B906 general requirements.
For the full grade file, start at the Hastelloy C-22 hub. The Hastelloy C-22 Bar and Rod and Hastelloy C-22 Pipe and Tube pages carry the other two forms.
Hastelloy C-22 plate, sheet, and strip covers UNS N06022 to ASTM B575 in the solution-annealed condition, cut to your blank list. Gauges run from 0.5 mm coil to 100 mm plate. Chromium above 20% makes flat product a lining choice for scrubber shells and reaction vessels that face oxidizing media. An EN 10204 3.1 certificate and heat-level traceability accompany each delivery.
Above all, nitric acid, wet chlorine, and ferric chloride duty is why a fabricator picks this plate over a lower-chromium grade.
In addition, molybdenum and tungsten keep hydrochloric, sulphuric, and phosphoric service inside the same lining.
Moreover, a molybdenum level near 13% holds pitting and crevice attack off wetted plate faces in brine and seawater.
Hot-rolled plate, cold-rolled sheet, and strip leave the mill water quenched.
Cold rolling, pressing, and welding carry on without an aging or stress-relief step.
As a result, plate at 100 mm and coil at 0.5 mm come from the same enquiry.
Finally, every certificate names a heat number beside its chemistry and mechanical results.
Flat C-22 sells on gauge discipline rather than on tonnage. We fix thickness, width, and edge condition against the forming step that follows your plate. Cutting and inspection scope then attach to the same order.
Thickness and width follow the rolling or pressing step your shop runs next, not a stock table.
Plasma, waterjet, and shear cutting produce blanks, rings, and circles from any stocked gauge.
Above all, ultrasonic testing, PMI, and third-party witness join the job where the service requires it.
Moreover, packing, Incoterm, and destination documents come from the same desk.
Melt, slab rolling, cold rolling, and a water-quenched anneal all precede the final cut on flat C-22 product. Still, the sequence shifts with the ordered gauge, standard, and acceptance level.
We weigh the charge to the N06022 window and hold carbon at 0.015% max through the melt.
AOD or vacuum treatment pulls carbon, silicon, and gas down, while ESR serves heats bound for critical duty.
The mill reduces slabs to plate gauge on a schedule written for the ordered thickness.
Likewise, cold mills take sheet and strip to final gauge, tightening tolerance and surface finish.
The line holds material at 1121 °C, then quenches it in water to dissolve intermetallic phases.
Leveling, cutting to size, and a final inspection against the ordered acceptance level close out the batch.
Flat C-22 stock runs from 0.5 mm coil through 100 mm plate. We agree thickness, width, length, and edge condition before the mill starts rolling. Consequently, the plan you approve at quotation reaches dispatch unchanged.
Plate rolling, annealing, and leveling lines operate on one site.
Hot mills, cold mills, shears, and levelers sit in one quality system.
Flat-product tonnage each month across standard and made-to-order gauges.
Metallurgists answer gauge, condition, and cutting questions before the order opens.
Chemistry, mechanics, gauge, and surface clear inspection before a plate leaves the bay. The whole sequence runs inside our ISO 9001 system. Beyond that, each delivery carries a mill certificate, and third-party inspection joins the order when required.
Spectrographic analysis holds the N06022 window, with carbon and silicon printed on the mill certificate.
Mechanical values come from the gauge and condition actually shipped.
We file thickness, flatness, and edge quality, and ultrasonic testing joins them where specified.
Consequently, a plate reaches its melting charge through the heat number on the certificate.
Four flat-product forms span the UNS N06022 range, each with its own finishing route under ASTM B575.
Solution-annealed plate from 4.8 mm up for vessel shells, scrubber liners, and ducting.
Request Availability →Sheet between 0.5 and 6.35 mm gives a smoother finish for fabricated equipment and linings.
Request Availability →Similarly, coil and strip in the same gauge band arrive slit to width for roll forming and stamping.
Request Availability →Circles, rings, and profiled blanks cut from any stocked gauge to your drawing.
Request Availability →Wetted surfaces in these vessels face acid and chloride attack at the same time. Thickness and blank size therefore follow the structure rather than a pressure rating.
Discuss Your Application →Absorber walls, ducting, and stack liners for chloride-laden flue gas.
Also, shell plate for reactors that run mixed mineral acids.
Plate that holds pressure on exchangers running acid and chloride duty.
Lining stock for hypochlorite, brine, and acid storage tanks.
Hood plate and washer parts for chlorine dioxide circuits.
Vessel plate for wet-process concentration trains.
Pressure plate for generator vessels and their piping spools.
Polished sheet serves reactor shells that must keep metal pickup low.
Stack liners, dampers, and duct plate for acidic flue products.

The UNS N06022 window below governs the B575 flat-rolled family. Chromium above 20% sets the oxidizing performance, molybdenum and tungsten carry the reducing and pitting side, and carbon stays at 0.015% max so welded seams keep their resistance. Nevertheless, the purchase specification in force decides acceptance.

ASTM International issues the flat-rolled documents. Besides, the ASME SB575 edition governs wherever a vessel falls under pressure-code jurisdiction.
Exposure between roughly 650 and 1090 °C during fabrication can precipitate intermetallic phases, so hot forming needs a follow-up solution anneal. Our engineers review that step with your shop before the plate leaves.
| Product Form | Typical Supply Range | Length |

Flat-product orders normally ship within two to four weeks of release, and heavy plate runs longer. Price settles once thickness, condition, and cutting scope match your fabrication plan.
Give thickness, width, length, quantity, and condition, along with the vessel or duct involved.
ASTM B575 covers industrial flat product, and B906 supplies the general requirements behind it.
Solution-annealed stock forms readily, so we agree blank geometry before the mill rolls.
The quotation sets out rolling route, cutting, testing, document scope, and Incoterm.
Rolling and annealing come first, then testing to the level agreed when the order was placed.
The consignment leaves with its 3.1 certificate, packing list, and export papers.

Flat-rolled C-22 product is ordered to ASTM B575, which sits alongside B906 general requirements. ASME SB575 applies under code jurisdiction.
Gauges run from 0.5 mm coil through 100 mm hot-rolled plate, cut to your length and width. Thicker sections still depend on slab supply.
Yes. Carbon at 0.015% max keeps grain-boundary carbides out of the weld zone, so post-weld heat treatment usually stays unnecessary.
Hot work above roughly 650 °C can precipitate intermetallic phases, so a follow-up solution anneal restores corrosion resistance. Tell us the forming route and we quote the re-anneal with the order.
Yes. Plasma, waterjet, and shear cutting produce blanks, rings, and circles from any stocked gauge.
Stocked gauges ship from one plate up, and trial lots carry no premium.
FOB serves as our standard term, and we price EXW, CIF, or DAP against a named destination.
The ordered gauge, width, and condition set the price, which we calculate by weight.
