Seamless and welded tubular product for reducing-acid lines, built so the joint keeps its properties after welding.
Welded Pipe Without Re-Annealing
The stability window lets most welded runs enter service as welded, which removes a furnace cycle from the schedule.
Seamless, Welded, Exchanger
Each tubular route carries its own specification, so one enquiry covers the whole run.
Cooling Data Attached
Every welded lot travels with the data that keeps the joint ductile.
PRODUCT OVERVIEW
About Hastelloy B-3 Pipe and Tube
Hastelloy B-3 Pipe and Tube carries the UNS N10675 grade in seamless and welded tubular form. Chromium between 1 and 3% slows the ordered phases, which matters most at a welded joint. Reducing acids stay inside the envelope, and oxidants do not.
Tubular product reaches plants as seamless tube, welded pipe, and welded exchanger tube. Above all, the welded routes are where this grade separates itself. The Hastelloy B-3 hub carries the alloy data, and the Hastelloy B-3 Bar and Rod and Hastelloy B-3 Plate and Sheet pages cover the other two routes.
PRODUCT FEATURES
Key Features of Hastelloy B-3 Pipe and Tube
Hastelloy B-3 pipe and tube carries the UNS N10675 grade in seamless, welded, and exchanger-tube form. Chromium between 1 and 3 percent slows Ni4Mo ordering, which is what a welded joint needs most. The nickel-molybdenum chemistry resists hydrochloric and sulfuric acid while the stream reduces, and it refuses oxidants outright. Southerly Alloy works as a professional supplier and exporter of tubular product to ASTM B622, B619, and B626.
Hastelloy B-3
Weld-Zone Stability
Chromium in the 1 to 3% range slows ordering, so a joint keeps more ductility than an earlier B-type weld would.
01
As-Welded Service
Moreover, carbon at 0.01% maximum lets most welded pipe leave the works without a post-weld anneal.
02
Hydrochloric Flow Duty
Moreover, the bore resists HCl from dilute streams to boiling while the circuit stays reducing.
03
Sulfuric and Formic Media
In addition, non-oxidizing sulfuric, formic, and acetic duty sits inside the envelope.
04
Chloride Attack Resistance
The nickel-rich matrix holds up wherever chlorides concentrate.
05
Seamless to the Standard Ceiling
Consequently, seamless tube stops where ASTM B622 stops, at 88.9 mm outside diameter.
06
Welded Pipe to Schedule 80S
Meanwhile, B619 pipe runs from Schedule 5S through 80S at 8 in nominal and larger.
07
Exchanger Tube Range
B626 welded tube spans 3.2 to 88.9 mm outside diameter.
08
WHY CHOOSE US
Why Choose Hastelloy B-3
A welded tubular run asks a different question than a machined part does. Can the joint keep its properties without a furnace cycle afterwards? For most B-3 fabrications the answer is yes, and that frees a schedule slot.
01
Weld Detail Reviewed
We look at the joint design and the heat input before quoting, because both decide the acceptance route.
02
Heat-Linked Certificates
Every report names the melt, with the pressure-test record filed beside the tensile results.
03
Bore Finish Agreed Early
In addition, pickled, bright annealed, or polished bores are fixed before drawing starts.
04
Tube Packed for Export
Ends are capped and lengths crated, then we quote FOB, CIF, or DAP against your port.
MANUFACTURING PROCESS
Reliable Production For Critical Applications
Welding heat is the point of risk in tubular work, so a B-3 run stays close to the anneal window. Therefore, the mill quenches every lot quickly after the furnace pass.
01
Shell Preparation
We cut and inspect the shell stock before the forming line takes it.
02
Forming and Welding
Roll forming closes the shell, and an automatic pass joins it without filler.
03
Weld Conditioning
The joint is sized and dressed so the bore stays continuous.
04
Solution Annealing
A furnace pass near 1066 °C returns the whole tube, weld included, to one phase.
05
Rapid Quenching
A fast water quench preserves that structure as the tube cools.
06
Cold Drawing
Drawing brings welded tube to its final diameter and wall where the order calls for it.
07
Pickling
An acid bath removes scale from both the bore and the outside surface.
08
Pressure Release
Hydrostatic or eddy-current testing clears the tube before dispatch.

Mechanical Properties
ASTM B622 sets a lower yield floor than the rod document does. Therefore, the table below reflects seamless product, and the welded routes follow their own documents.
| Product Form | Condition | Tensile Strength | Yield Strength, 0.2% Offset | Elongation |
|---|---|---|---|---|
| Seamless pipe and tube, ASTM B622 | Solution annealed and descaled | ≥110 ksi (760 MPa) | ≥45 ksi (310 MPa) | 40% |
B619 welded pipe and B626 welded tube carry their own acceptance minima. Consequently, we quote those figures from the edition your purchase order names.
Physical Properties
Values below are typical room-temperature figures for design work rather than acceptance criteria. In addition, the alloy stays essentially non-magnetic in the annealed condition.
| Property | Value |
|---|---|
| Density | Approx. 9.22 g/cm³ |
| Melting range | Approx. 1370–1418 °C |
| Modulus of elasticity | Approx. 216 GPa |
| Modulus of rigidity | Approx. 83 GPa |
| Thermal conductivity at 20 °C | Approx. 11.2 W/m·K |
| Electrical resistivity at 20 °C | Approx. 1.37 µΩ·m |
| Thermal expansion, 25–100 °C | Approx. 10.6 µm/m·K |
| Magnetic behaviour | Essentially non-magnetic in the annealed condition |
Standards
Seamless product answers to ASTM B622, and that document stops at 88.9 mm outside diameter. Beyond it, welded work follows B619 for pipe and B626 for exchanger tube. Meanwhile, the designations below identify the same melt.

The tubular documents come from ASTM International, and their text settles any acceptance question.
Dimensions
Each document sets its own size window, so a seamless ceiling and a welded size list tell different stories. Therefore, state the route and the dimensions together.
| Product Form | Outside Diameter | Wall Thickness |
|---|---|---|
| Seamless pipe and tube, ASTM B622 | Up to 88.9 mm | 0.5–12.7 mm |
| Welded pipe, ASTM B619 | Schedule 5S through 80S, 8 in nominal and larger | Per schedule |
| Welded tube, ASTM B626 | 3.2–88.9 mm | 0.41–3.7 mm |
| U-bend tube | As drawn, bent to drawing | 0.7–6 mm |
Surface Finishes
The bore finish decides how well the tube cleans and how long the line lasts. In short, we fix it with the order rather than assume one.
| Surface Condition | Typical Use |
|---|---|
| Solution annealed and pickled | Standard delivery for hydrochloric and sulfuric acid service |
| Bright annealed | Scale-free bore for instrument and clean circuits |
| Polished bore | Reduced roughness for product-contact lines |
| Mechanically descaled | Welded product cleaned without acid pickling |
