PRODUCT OVERVIEW
About Hastelloy B-2 Welding Wire
Hastelloy B-2 welding wire covers the two fillers classified for repair work on UNS N10665 plant. This Hastelloy B-2 welding wire runs as ERNiMo-7 per AWS A5.14 in bare form. Besides, the matching covered electrode runs as ENiMo-7 per AWS A5.11.
We supply Hastelloy B-2 welding wire as straight TIG lengths, wound MIG spools and sealed electrode packs. The deposit carries the reducing-acid performance of the parent metal into the repair, and it also joins the steel behind a lining.
Meanwhile, the base-metal chemistry behind this Hastelloy B-2 welding wire sits on our Hastelloy B-2 material page for weld procedure work.
PRODUCT FEATURES
Key Features of Hastelloy B-2 Welding Wire
Hastelloy B-2 welding wire arrives in UNS N10665, the nickel-molybdenum grade whose molybdenum sits at 26.0–30.0% while chromium stops at 1%, so hydrochloric acid at any concentration meets a surface it cannot oxidise. We supply ASTM B335 welding wire as ERNiMo-7 bare wire and as ENiMo-7 covered electrodes for hydrogen chloride synthesis, steel pickling lines and acid regeneration hardware. Every Hastelloy B-2 welding wire consignment travels with heat-number traceability, EN 10204 3.1 mill test reports and full export documentation.

TECHNICAL INFORMATION
Technical Specifications
Detailed technical information including chemical composition, mechanical properties, standards and available dimensions.
Chemical Composition
Molybdenum runs 26.0–30.0% in this welding wire under the B335 composition table, the highest molybdenum level any wrought nickel alloy carries. Besides, chromium stops at 1.0% maximum and iron at 2.0% maximum, so a reducing acid meets a surface with nothing it can oxidise.
For the element-by-element limits behind this welding wire, open the composition breakdown held on the Hastelloy B-2 material page.
Mechanical Properties
All-weld-metal figures for the fillers supplied with Hastelloy B-2 welding wire appear below. Note that the bare wire classification carries no tensile floor from AWS, so the deposit chemistry and the test report carry the release.
| Product (all-weld metal) | AWS Class | Tensile Strength | Elongation |
|---|---|---|---|
| ERNiMo-7 bare wire | AWS A5.14, UNS N10665 | 690–760 MPa (100–110 ksi), typical | 20–30%, typical |
| ENiMo-7 covered electrode | AWS A5.11 | 690 MPa (100 ksi) and above, typical | 20% and above, typical |
- The A5.14 NiMo classes are classified on chemistry, so the ERNiMo-7 classification carries no tensile floor and the all-weld-metal figures in the test report govern the release. Moreover, the matching electrode is the ENiMo-7 covered type to AWS A5.11. Besides, no aerospace document reaches this grade, so filler is ordered against the AWS classification alone.
Physical Properties
Identification data for the parent metal and for both deliveries appears below for this Hastelloy B-2 welding wire.
| Property | Value |
|---|---|
| Parent Metal | UNS N10665, 2.4617 / NiMo28 |
| Bare Filler | ERNiMo-7 (AWS A5.14) |
| Covered Electrode | ENiMo-7 (AWS A5.11) |
| Molybdenum | 26.0–30.0% in the parent metal |
| Chromium | 1.0% max. in the parent metal |
| Carbon | 0.02% max. in the parent metal |
| Nickel | Balance in the parent metal |
| Strengthening Route | Cold work only, because the grade does not respond to aging |
Filler Metal Classifications
Specifically, classification data for the two products below sets out the deposit side of this Hastelloy B-2 welding wire.
| Product | AWS Class | Chemistry Basis | Typical Strength | Best Suited For |
|---|---|---|---|---|
| Bare wire | ERNiMo-7 (A5.14) | Deposits the parent window: Ni balance, Mo 26.0–30.0%, Cr 1.0% max., Fe 2.0% max. | 690–760 MPa (100–110 ksi) typical | GTAW primary, GMAW general |
| Covered electrode | ENiMo-7 (A5.11) | Deposits the same Ni-Mo analysis under a basic covering | 690 MPa (100 ksi) and above, typical | SMAW repair and build-up |
Standards
The bare filler for this welding wire runs as ERNiMo-7 under AWS A5.14, a classification issued by the American Welding Society. Moreover, AWS A5.11 covers the ENiMo-7 electrode that pairs with this welding wire.

| Standard | Product or Application |
|---|---|
| AWS A5.14 | ERNiMo-7 bare filler wire, UNS N10665 |
| AWS A5.11 | ENiMo-7 covered electrode |
| ASME SFA-5.14 | ASME version of the bare filler specification |
Finally, the full standards list that the Hastelloy B-2 material page holds adds the plate, tube and fitting documents, the Chinese designation and the remaining product standards behind this welding wire.

Surface Finishes
Finish decides how this welding wire holds up in hydrogen chloride synthesis, absorption towers and acid regeneration loops, and most stock leaves our yard solution annealed and pickled so the reducing-acid surface arrives ready. Specifically, we agree the finish on this Hastelloy B-2 welding wire before the order leaves the desk.
| Surface Condition | Typical Use |
|---|---|
| Clean Bright | The standard surface for bare ERNiMo-7 welding wire, free of drawing lubricant. |
| Straight Rods | Cut TIG rods of this welding wire with clean, deburred ends. |
| Coated | A light carrier film on this welding wire that protects it through storage and handling. |
Meanwhile, the surface finishes table recorded on the Hastelloy B-2 material page lists the remaining conditions quoted for this welding wire.

FAQ
Frequently Asked Questions
Which AWS classification covers the filler for this Hastelloy B-2 welding wire?
ERNiMo-7 per AWS A5.14 covers the bare form of this Hastelloy B-2 welding wire, and ENiMo-7 per AWS A5.11 covers the covered electrode.
Does AWS set a tensile floor on the bare wire for this grade?
No. The A5.14 NiMo classes are classified on chemistry rather than strength, so we report all-weld-metal values from the test certificate.
Does a repair in this grade need a post-weld heat treatment?
It depends on the duty. Severe acid service calls for a solution anneal at 1050–1100 °C and a water quench, while a light repair usually enters service as welded.
Which contaminants rule this Hastelloy B-2 welding wire out?
Ferric ions, cupric ions, nitric acid and hypochlorite, so filler work on this Hastelloy B-2 welding wire has to confirm an oxidant-free stream.
How is the price of this Hastelloy B-2 welding wire calculated?
Weight in kilograms drives pricing for this Hastelloy B-2 welding wire, with the prevailing nickel and molybdenum quotations applied on the order date.
What is your MOQ for this Hastelloy B-2 welding wire?
A single sealed tube or spool covers many common diameters of this Hastelloy B-2 welding wire.
