Incoloy 925 Rods (UNS N09925)
Round rod, welding rod, pump-shaft rod, machined-component rod ASTM B805
Incoloy 925 rods (UNS N09925) is the broad rod-form category for the alloy, encompassing solid round rod stock per ASTM B805 for downstream machining, welding-rod (filler-wire form, AWS A5.14 ER class) for matching-strength weld deposit, pump-shaft long-form rod for sour-service rotating machinery, and tie-rod / connecting-rod stock for tension-loaded structural members. Distinct from bars (which is the broader mill-product category including hex / square / flat sections) and threaded rods (continuous-thread form), this page covers UNTHREADED solid-round rod stock supplied for further fabrication. TorqBolt manufactures Incoloy 925 rods in 6 mm to 200 mm diameter, lengths to 6 m, in the solution-annealed and aged condition with hardness controlled within the 35 HRC NACE MR0175 sour-service cap.

Rod Variants Manufactured
| Variant | Description | Use |
|---|---|---|
| Round rod (general purpose) | Solid round bar stock, hot-rolled / cold-drawn / ground | Downstream machining of fittings, pins, sleeves, tools |
| Welding rod (bare filler wire) | 1/16" to 3/16" diameter; AWS A5.14 ERNiCrMo-15 chemistry (matching INCO-WELD 725NDUR) | GTAW (TIG) filler for matching-strength Incoloy 925 welds; see welding spec |
| Pump-shaft rod (long-form) | Long round rod (3 to 6 m) precision-ground for shaft service | Sour-service centrifugal-pump shafts in oilfield production |
| Connecting-rod stock | Round rod sized for tension-loaded structural connecting members | Marine + structural tension members |
| Coiled rod | Small-diameter rod (3 to 12 mm) supplied in coil for further drawing | Wire-drawing input + small-section rolling |
Welding Rod Variant, AWS Reference
Welding-rod form of Incoloy 925 is supplied per AWS A5.14 ERNiCrMo-15 (matching INCO-WELD® 725NDUR filler) for matching-strength Incoloy 925 weld deposits. Used for GTAW (TIG) and GMAW (MIG). Bare-wire form 1/16", 3/32", 1/8" (1.6 / 2.4 / 3.2 mm) common for stick electrodes; spool form for automatic / semi-automatic welding. Post-weld solution anneal + age cycle required for full property recovery in the joint, see welding page for filler-selection logic.
Standard Size Range
| Diameter | Process | Length |
|---|---|---|
| 1.6 mm to 6 mm (welding wire) | Cold-drawn precision; spool or cut | 1 m cut, 5–15 kg spools |
| 6 to 25 mm (general) | Cold-drawn (h9) / ground (h6) | 1 to 6 m random |
| 25 to 100 mm (machining stock) | Hot-rolled + peeled / ground | 3 to 6 m random |
| 100 to 200 mm (large stock) | Hot-rolled / hot-forged | 2 to 6 m |
Mechanical Properties (Aged)
Tensile 165 ksi min / Yield 110 ksi min / Elongation 18% min / Hardness 32–35 HRC (NACE cap). For welding-rod variant: properties apply to the as-deposited weld metal after PWHT solution-anneal + age. See mech properties page.

Frequently Asked Questions
What's the difference between rods and bars? Largely a naming convention, both are solid round mill product. "Bar" tends to mean stock for fastener / forging input (broader cross-section variants: round / hex / square / flat); "rod" tends to mean round-only stock for downstream machining or welding-filler form. TorqBolt supplies the same metallurgy under both names.
Welding rod vs INCO-WELD 725NDUR, same thing? Yes, INCO-WELD 725NDUR is the trade name; AWS A5.14 ERNiCrMo-15 is the standard classification. Both refer to the same matching-composition filler used for joining Incoloy 925.
Lead time? Standard rod (15 to 50 mm): 4–6 weeks. Welding wire / filler form: 6–8 weeks. Pump-shaft long-form (3–6 m): 8–10 weeks.
