PRODUCT FEATURES
Key Features of Hastelloy C-276 Round Bar
Hastelloy C-276 round bar arrives in UNS N10276, the nickel-molybdenum-chromium-tungsten grade whose molybdenum and tungsten face reducing acids while chromium covers oxidising media. We provide ASTM B574 round bar in hot-worked, solution-annealed and cold-drawn conditions, cut to length for wet chlorine plants, hydrochloric acid service and flue-gas desulfurisation hardware. Every Hastelloy C-276 round bar order carries heat-number traceability, EN 10204 3.1 mill test reports and full export documentation.
Hastelloy C-276
Wet Chlorine Resistance
For example, molybdenum and tungsten in this Hastelloy C-276 round bar hold up where moist chlorine destroys stainless steel.
01
Hydrochloric Acid Capability
Specifically, this Hastelloy C-276 round bar serves hydrochloric acid across the full concentration range.
02
Mixed Acid-Chloride Coverage
Moreover, one stream can carry oxidising and reducing species at once, and this Hastelloy C-276 round bar meets both.
03
NACE MR0175 Qualification
Besides, UNS N10276 sits inside NACE MR0175 / ISO 15156, so this Hastelloy C-276 round bar enters H2S duty with a hardness record.
04
Ultra-Low Carbon Weld Zones
In addition, carbon at 0.010% max and silicon at 0.08% max leave no carbides in this Hastelloy C-276 round bar to precipitate.
05
Chloride Pitting Resistance
Therefore, molybdenum at 15.0–17.0% lifts the pitting and crevice resistance of this Hastelloy C-276 round bar in chloride liquor.
06
Cold-Work Strength
Consequently, drawing raises the yield strength of this Hastelloy C-276 round bar above the annealed floor where shafts need it.
07
Non-Magnetic Behaviour
Finally, this Hastelloy C-276 round bar stays practically non-magnetic at ambient temperature for instrument work.
08

TECHNICAL INFORMATION
Technical Specifications
Detailed technical information including chemical composition, mechanical properties, standards and available dimensions.
Chemical Composition
ASTM B574 holds nickel at 57.0% minimum and chromium between 14.5% and 16.5% for this round bar, with molybdenum at 15.0–17.0% as the leading addition. Moreover, tungsten at 3.0–4.5% reinforces the passive film carried by this round bar, while carbon at 0.010% maximum and silicon at 0.08% maximum starve the grain-boundary precipitates that embrittle welded joints.
For the complete element-by-element limits, open the composition breakdown held on the Hastelloy C-276 material page for this round bar.
Mechanical Properties
The minimum room-temperature values below follow the rod and bar table of ASTM B574 for UNS N10276. Consequently, the ordered condition and hardness basis govern final acceptance of Hastelloy C-276 round bar.
| Condition and Grade | Tensile Strength, min. | Yield Strength (0.2%), min. | Elongation, min. |
|---|---|---|---|
| Solution Annealed — UNS N10276 | ≥690 MPa (100 ksi) | ≥283 MPa (41 ksi) | 40% |
- ASTM B574 sets one solution-annealed condition for rod and bar at these minimums, and its Table 5 carries no hardness requirement at all. Moreover, clause 1.2.3 reaches cold-worked stock from 6.35 to 88.9 mm, where N10276 sits among the listed grades, so drawn and ground bar holds strength above the annealed floor. Therefore, sour-service orders travel with a per-heat hardness record against the 35 HRC ceiling rather than a mill hardness maximum.
Physical Properties
Published references place this round bar at a density near 8.89 g/cm³ with a melting range of 1325–1370 °C. Moreover, the nickel-rich matrix keeps this round bar practically non-magnetic at ambient temperature, which suits instrument and sensor assemblies. Besides, the solid-solution structure holds these values across the whole solution-annealed range.
Meanwhile, the physical properties table on the Hastelloy C-276 material page holds the modulus, the thermal expansion and the remaining design values behind this round bar.
Heat Treatment
The water-quenched anneal is the specification-defining step for this grade, because rapid cooling after 1120–1160 °C restores the corrosion resistance the media demand. In addition, we supply this Hastelloy C-276 round bar in whichever condition your duty calls for.
| Condition | Typical Treatment |
|---|---|
| Solution Annealed | Held between 1120 and 1160 °C, then water quenched to dissolve the precipitates that follow slow cooling |
| Hot-Worked | Delivered as-rolled or as-forged, with the anneal agreed where the order calls for it |
| Cold-Drawn | Drawn after annealing, with the reduction recorded so the higher yield strength is documented |
| Slow-Cool Hazard | Cooling slowly through the 650–1090 °C band precipitates μ and P phases, so a rapid quench follows every anneal |
| Sour-Service Release | NACE MR0175 orders carry a per-lot hardness record against the 35 HRC ceiling |
Standards
ASTM B574 is the principal rod and bar document for this round bar, published by ASTM International, and its scope reaches eleven UNS numbers with N10276 among them. Moreover, ASME SB574 covers pressure equipment while its cold-worked clause governs drawn and ground stock of this round bar. Besides, DIN 17752, ISO 9723 and VdTÜV 400 serve European and international orders.
| Standard | Product or Application |
|---|---|
| ASTM B574 / ASME SB574 | Nickel-chromium-molybdenum-tungsten rod and bar, UNS N10276 among eleven grades |
| DIN 17752 / ISO 9723 | German and international bar documents |
| VdTÜV 400 / NACE MR0175 | German data sheet and sour-service qualification |
Finally, the full standards list on the Hastelloy C-276 material page adds the pressure documents, the European designations and the remaining product documents behind this round bar.

Surface Finishes
Finish decides how this round bar behaves across wet chlorine streams, chlorine dioxide bleach plants and FGD scrubbers, and most stock ships solution annealed and pickled so the surface reaches your shop ready for acid service. Specifically, we fix the finish on this Hastelloy C-276 round bar before the order is released.
| Surface Condition | Typical Use |
|---|---|
| Solution Annealed and Pickled | Annealing followed by acid descaling leaves this round bar scale-free for wet chlorine and reducing-acid duty. |
| Hot-Worked | As-rolled or as-forged surface on this round bar, for parts that will be machined all over. |
| Peeled | A machined skin on this round bar with a uniform diameter for acid-plant shaft work. |
Meanwhile, the surface finishes table on the Hastelloy C-276 material page lists the remaining conditions we quote for this round bar.
