01
Hot-Rolled Plate
Annealed and pickled plate from 4.76 to 63.5 mm thick.
Request Availability →Hastelloy B-2 Plate and Sheet
Flat-rolled product for linings, trays, and vessel internals in reducing acid service, where oxidants are fatal.
Thickness Band Settled First
Plate and sheet split at 4.76 mm, so the classification is fixed before a price leaves the desk.
Flatness Tied to the Order
Consequently, flatness and edge condition go on the specification rather than staying open.
Faces Protected in Transit
Each bundle is interleaved and crated so the pickled surface arrives ready for fabrication.
PRODUCT OVERVIEW
About Hastelloy B-2 Plate and Sheet
Hastelloy B-2 Plate and Sheet carries the UNS N10665 grade as flat-rolled product. Reducing acids attack the surface very little, while oxidants do the opposite. Exposure between 540 and 815 °C orders the metal into Ni4Mo and costs ductility.
Flat product from this grade reaches fabricators as plate, sheet, and strip. The Hastelloy B-2 hub holds the alloy data, and the Hastelloy B-2 Bar and Rod and Hastelloy B-2 Pipe and Tube pages cover the other two routes.
PRODUCT FEATURES
Key Features of Hastelloy B-2 Plate and Sheet
Hastelloy B-2 plate and sheet carries the UNS N10665 grade as flat-rolled product to ASTM B333. The nickel-molybdenum chemistry resists hydrochloric and sulfuric acid while the stream reduces, and it tolerates no oxidant at all. Ni4Mo orders between 540 and 815 °C, so forming and welding heat must pass through that band quickly. Southerly Alloy works as a professional supplier and exporter of flat product from 4.76 to 63.5 mm plate down through light sheet and strip.
Hastelloy B-2
Surface-Side Hydrochloric Duty
Moreover, concentration and temperature stay inside the envelope while the stream reduces.
01
Reducing Acid Range
Consequently, non-oxidizing sulfuric, phosphoric, and organic acids stay within reach of the flat product.
02
Stress-Cracking Immunity
Nickel dominance keeps chloride-bearing media from cracking the plate face.
03
Thickness Bands Defined
Therefore, ASTM B333 covers plate from 4.76 to 63.5 mm thick.
04
Light Sheet and Strip
Meanwhile, sheet and strip run under 4.76 mm for liners and formed parts.
05
Weldable Without Post-Weld Anneal
Carbon at 0.02% or less limits weld-zone precipitation, so many linings need no further anneal.
06
Flatness Recorded
In addition, we fix flatness and edge condition at quotation rather than leaving them open.
07
Mid-Temperature Exclusion
Ni4Mo ordering between 540 and 815 °C governs how we schedule annealing after forming.
08
WHY CHOOSE US
Why Choose Hastelloy B-2
Hastelloy B-2 plate and sheet orders hinge on two things. First, the thickness band that decides whether the mill calls the product plate or sheet. Then, the flatness and edge condition the fabrication shop needs.
01
Thickness Band Confirmed
Consequently, we confirm the plate or sheet classification before quoting, because thickness and width together decide it.
02
Documents Anchored to the Melt
EN 10204 3.1 certificates carry chemistry, tensile results, and the anneal record.
03
Sizes Cut to Your Nest
In addition, plate is cut to your length and width, so offcuts stay at our works.
04
Export Packing for Flat Product
We protect the face and the edge, then quote FOB, CIF, or DAP against your port.
MANUFACTURING PROCESS
Reliable Production For Critical Applications
Flat product starts as a slab that must reach one annealed condition across the whole plate. Consequently, the mill holds thickness and temperature together through rolling.
01
Slab Preparation
We dress and inspect the slab before the rolling line takes it.
02
Hot Rolling
The mill reduces the slab toward plate gauge at temperature.
03
Intermediate Anneal
A furnace cycle softens the plate so the next pass can bite.
04
Cold Rolling
Sheet and strip reach final gauge on cold mills, where thickness holds tightly.
05
Solution Annealing
The mill returns the product to a single phase near 1065 °C before the final cool.
06
Quench and Cool
A fast drop through the mid range keeps the ordered phases from returning.
07
Pickling and Descaling
Acid cleaning leaves a scale-free surface ready for fabrication.
08
Flatness and Gauge Release
Flatness, thickness, and edge condition clear before the plate is packed.

QUALITY ASSURANCE
Strict Quality Control From Production To Delivery
Release evidence follows the flat-product document on your order. Chemistry runs against the N10665 window, and gauge plus flatness records accompany the plate.
01
Per-Heat Chemistry
The lab measures molybdenum, iron, and carbon against the B333 limits.
02
Gauge and Flatness Records
Meanwhile, thickness, width, and flatness readings travel with the release papers.
03
Grain Size on Request
The lab reports grain size against ASTM E112 when the order asks for it.
04
Certificates Anchored to the Melt
Each report names the heat, so inspection can trace one plate.

TECHNICAL INFORMATION
Technical Specifications
Detailed technical information including chemical composition, mechanical properties, standards and available dimensions.
Chemical Composition
Limits below follow ASTM B333 for UNS N10665 flat product, with nickel making up the balance. Iron and chromium stay low because they drive Ni4Mo formation. The mill certificate governs final acceptance.
| Element | Content |
|---|---|
| Nickel (Ni) | Balance |
| Molybdenum (Mo) | 26.0–30.0% |
| Iron (Fe) | 2.0% max. |
| Chromium (Cr) | 1.0% max. |
| Cobalt (Co) | 1.00% max. |
| Manganese (Mn) | 1.0% max. |
| Carbon (C) | 0.02% max. |
| Silicon (Si) | 0.10% max. |
| Phosphorus (P) | 0.04% max. |
| Sulfur (S) | 0.03% max. |
Mechanical Properties
Plate and light flat product share one set of minimums, and the table below separates them by thickness band. As a result, the ordered thickness tells you which row governs acceptance.
| Product Form | Condition | Tensile Strength | Yield Strength, 0.2% Offset | Elongation | Hardness |
|---|---|---|---|---|---|
| Plate, ASTM B333, 4.76–63.5 mm | Solution annealed and descaled | ≥110 ksi (760 MPa) | ≥51 ksi (350 MPa) | 40% | 100 HRB max. |
| Sheet and strip, ASTM B333, under 4.76 mm | Solution annealed and descaled | ≥110 ksi (760 MPa) | ≥51 ksi (350 MPa) | 40% | 100 HRB max. |
The grade is not age hardenable, so cold rolling is the only route to higher strength. Sheet and strip ordered deep-drawing quality carry a grain size requirement beside the tensile figures.
Physical Properties
Typical room-temperature values below support design work rather than acceptance testing. In addition, the alloy stays non-magnetic in the annealed condition.
| Property | Value |
|---|---|
| Density | Approx. 9.22 g/cm³ |
| Melting range | Approx. 1330–1380 °C |
| Modulus of elasticity | Approx. 217 GPa |
| Thermal conductivity at 0 °C | Approx. 11.1 W/m·K |
| Thermal conductivity at 100 °C | Approx. 12.2 W/m·K |
| Electrical resistivity at 20 °C | Approx. 1.37 µΩ·m |
| Thermal expansion, 20–93 °C | Approx. 10.3 µm/m·K |
| Magnetic behaviour | Non-magnetic in the annealed condition |
Standards
ASTM B333 covers plate, sheet, and strip, and the ASME edition takes over under pressure-code jurisdiction. Specifically, thickness and width together decide which of the three names applies. Meanwhile, the designations below identify the same melt.

| ASTM B335 / ASME SB335 | Rod in the same grade |
| ASTM B622 / ASME SB622 | Seamless pipe and tube |
| ASTM B619 / ASME SB619 | Welded pipe |
| ASTM B626 / ASME SB626 | Welded tube |
| ASTM B564 / ASME SB564 | Forgings |

| GB/T 15007 NS322 | Chinese designation |
| SAE AMS | No aerospace specification covers this grade |
The flat-product documents come from ASTM International, and their text settles any acceptance question.
Dimensions
Ranges below follow the scope ASTM B333 sets, where thickness and width together fix the product name. For that reason, give both measurements on the enquiry.
| Product Form | Typical Supply Range |
|---|---|
| Plate | 4.76–63.5 mm thick, width above 250 mm |
| Sheet | Under 4.76 mm thick, width from 600 mm |
| Strip | Under 4.76 mm thick, width under 600 mm |
| Cut Plate | Sheared or plasma cut to ordered length and width |
| Coil | Strip supplied coiled for press and lining work |
Surface Finishes
The finish decides how easily a lining cleans and how long it holds in acid service. In short, we agree it with the order rather than assume a default.
| Surface Condition | Typical Use |
|---|---|
| Annealed and pickled | Standard delivery for hydrochloric and sulfuric acid service |
| Hot-rolled and descaled | Parts that will be machined or further formed |
| Cold-rolled, bright finish | Uniform face for vessel internals and visible panels |
| Bright annealed | Scale-free surface for clean and product-contact service |
| Polished | Reduced roughness for high-purity and decorative work |
