Hastelloy C-276 Seamless Pipe
Pressure and transfer lines to ASTM B622, in hot-finished or cold-finished condition.
Request Availability →Hastelloy C-276 Pipe and Tube — B622 Tubulars
Seamless and welded UNS N10276 tubular product to B622, B619, and B626 for acid, chloride, and wet-chlorine duty.
Seamless and Welded Coverage
We quote B622 seamless product alongside B619 pipe and B626 tube under a single UNS N10276 enquiry.
Post-Weld Anneal as Standard
Every welded length leaves the plant solution annealed and water quenched, so it meets the ordered document.
Wet-Chlorine Tubulars
Moist chlorine, hypochlorite, and chlorine dioxide dissolve most metals, and tubular C-276 outlasts them all.
PRODUCT OVERVIEW
About Hastelloy C-276 Pipe and Tube
Hastelloy C-276 Pipe and Tube serves chemical and pollution-control lines where one process stream mixes oxidizing and reducing attack. Molybdenum and tungsten suppress reducing-acid and chloride attack while chromium covers oxidizing media. Each length follows B622, B619, or B626.
Grade-level data sits on the Hastelloy C-276 hub, and the two other forms are covered on the Hastelloy C-276 Bar and Rod and Hastelloy C-276 Plate and Sheet pages.
PRODUCT FEATURES
Key Features of Hastelloy C-276 Pipe and Tube
Hastelloy C-276 pipe and tube covers seamless product to ASTM B622 plus welded pipe to B619 and welded tube to B626, quoted against schedule, gauge, or drawing. Sizes run from small condenser tube to NPS 24 line pipe, supplied solution annealed and water quenched. Molybdenum and tungsten carry these lines through hydrochloric and sulphuric acid, wet chlorine, and chloride-bearing slurry. EN 10204 3.1 certificates and heat-level traceability back chemical, FGD, and sour-service projects.
Hastelloy C-276
Hydrochloric Acid Service
In addition, tubular product handles HCl across a wide concentration range, subject to each line's temperature limit.
01
Wet Chlorine and Hypochlorite
Indeed, moist chlorine gas, hypochlorite liquor, and chlorine dioxide leave few metals intact.
02
Pitting and Crevice Resistance
Molybdenum at 15.0–17.0% keeps localised attack in check where seawater or chloride liquor wets the wall.
03
Chloride SCC Immunity
Chloride-induced stress-corrosion cracking does not trouble a nickel-rich matrix of this type.
04
As-Welded Corrosion Resistance
Carbon at 0.010% max leaves the weld heat-affected zone free of grain-boundary precipitates.
05
Flare and Flattening Tests
Besides, B622 carries the ductility evidence that tube expansion into tubesheets requires.
06
Eddy-Current Inspection
Also, B626 welded tube passes 100% eddy-current or ultrasonic examination before release.
07
Sour-Service Tubulars
Meanwhile, process piping for H2S duty travels with NACE MR0175 / ISO 15156 hardness records.
08
WHY CHOOSE US
Why Choose Hastelloy C-276
For tubular work, Southerly Alloy keeps the commercial relationship while audited partner plants pierce, weld, and finish the tube. Your enquiry goes straight to the mill that runs that production route. Consequently, you settle condition and documentation questions in a single thread.
01
Route Matched to the Duty
Pressure, diameter, medium, and budget fix the seamless or welded choice before the quotation leaves.
02
One Desk for the Whole Range
Condenser tube at 6 mm OD and line pipe at NPS 24 come from the same quotation desk.
03
Testing Scope Fixed at Order
Hydrostatic, eddy-current, PMI, and third-party inspection attach at purchase stage.
04
Delivery Planning
Packing, Incoterm, and export paperwork clear before dispatch.
MANUFACTURING PROCESS
Reliable Production For Critical Applications
Every UNS N10276 heat moves through melt, hot working, cold finishing, and a water-quenched anneal before release. In addition, the sequence shifts with the standard, gauge, and acceptance level on the order.
01
Charge Preparation
We weigh nickel, chromium, molybdenum, tungsten, and iron into the N10276 window before the melt begins.
02
Vacuum Refining
VIM or AOD treatment holds carbon, silicon, and gas content inside the limits that protect weld zones.
03
Hot Working
Billets take a pierce or extrusion pass into seamless shells, while welded product starts from flat-rolled coil.
04
Cold Finishing
Cold pilgering or drawing brings condenser and precision tube down to final outside diameter and wall.
05
Solution Annealing
Material passes through 1120 to 1160 °C, then takes a rapid water quench that dissolves precipitates.
06
Welding and Re-Annealing
Welded lengths receive a matching ERNiCrMo-4 seam, then a full solution anneal and quench.
07
Finishing and Testing
Our operators pickle and dimension-check each length, run hydrostatic or eddy-current tests, and release it against the ordered acceptance level.

TECHNICAL INFORMATION
Technical Specifications
Detailed technical information including chemical composition, mechanical properties, standards and available dimensions.
Chemical Composition
The window below covers the B622, B619, and B626 tubular family for UNS N10276. Molybdenum and tungsten drive reducing-acid and chloride resistance, chromium carries oxidizing duty, and carbon stays ultra-low to protect welded seams. However, the purchase specification in force decides acceptance.
| Element | Content |
|---|---|
| Nickel (Ni) | 57.0% min. (balance) |
| Molybdenum (Mo) | 15.0–17.0% |
| Chromium (Cr) | 14.5–16.5% |
| Tungsten (W) | 3.0–4.5% |
| Iron (Fe) | 4.0–7.0% |
| Cobalt (Co) | 2.50% max. |
| Manganese (Mn) | 1.00% max. |
| Vanadium (V) | 0.35% max. |
| Silicon (Si) | 0.08% max. |
| Carbon (C) | 0.010% max. |
| Phosphorus (P) | 0.040% max. |
| Sulphur (S) | 0.030% max. |
Mechanical Properties
Minimum room-temperature values below follow the governing standard and the solution-annealed condition. Therefore, name the ASTM document and the ordered wall thickness at enquiry so acceptance is unambiguous.
| Product Form | Standard | Condition | Tensile Strength | Yield Strength, 0.2% Offset | Elongation |
|---|---|---|---|---|---|
| Seamless pipe and tube | ASTM B622 | Solution annealed | ≥690 MPa (100 ksi) | ≥283 MPa (41 ksi) | ≥40% |
| Welded pipe | ASTM B619 | Solution annealed after welding | ≥690 MPa (100 ksi) | ≥283 MPa (41 ksi) | ≥40% |
| Welded tube | ASTM B626 | Solution annealed after welding | ≥690 MPa (100 ksi) | ≥283 MPa (41 ksi) | ≥40% |
B622 adds hydrostatic, flattening, and flare tests to seamless product. B626 brings a 100% eddy-current or ultrasonic examination, which suits exchanger duty. Meanwhile, no dedicated AMS document covers C-276 tubular product, so aerospace tube follows the project specification or the ASTM document named on the order.

FAQ
Frequently Asked Questions
Which ASTM standard covers Hastelloy C-276 seamless pipe?
Seamless pipe and tube are ordered to ASTM B622, while welded pipe follows B619 and welded tube follows B626. Under code jurisdiction the ASME SB editions apply.
Does welded C-276 pipe need heat treatment after welding?
Yes. B619 and B626 both require a full solution anneal and water quench after welding. For that reason, we do not quote as-welded pipe as standard-compliant product.
What is the maximum temperature for C-276 tubing?
Supplier data documents continuous air service to roughly 540 °C. However, the medium, its concentration, and the pressure rating usually set the real ceiling, so confirm the duty at enquiry.
What sizes are available for welded C-276 tube?
Welded tube to B626 runs from OD 3.18 mm to 127 mm, with walls from 0.38 mm to 12.7 mm. Larger or heavier sections come from a separate quote.
Is C-276 pipe suitable for sour service?
Sour-service orders run to NACE MR0175 / ISO 15156 with per-heat hardness records. Therefore, upstream projects can file the evidence their material review needs.
What is the lead time for Hastelloy C-276 pipe?
Stock sizes ship 7-15 days, while made-to-order and heavy-wall product runs against the confirmed production schedule.
What is your MOQ for Hastelloy C-276 pipe?
One piece covers many stock sizes, so trial lengths and repair pieces carry no premium hurdle.
What are your trade terms for Hastelloy C-276 pipe?
FOB is the default Incoterm, while EXW, CIF, and DAP quotes follow confirmed destinations.
How is Hastelloy C-276 pipe priced?
Pricing follows the ordered size, wall, and condition, and we normally calculate it by weight in kilograms. We confirm the applicable Incoterm on the offer.
Do you provide EN 10204 3.1 or 3.2 certificates?
Yes. Every delivery carries an EN 10204 3.1 certificate, and we arrange third-party 3.2 endorsement on request.
