Small Diameter Hastelloy Round Bars 6 - 100mm EN 2.4819 Alloy Rod in 6m Length
Hastelloy C276 (designated as EN 2.4819 under European standards) is a premium nickel-molybdenum-chromium alloy renowned for its exceptional corrosion resistance in harsh environments. The small-diameter round bars (6-100mm) with a standard length of 6m combine this alloy’s inherent performance advantages with dimensional precision, making them ideal for high-demand industrial applications where reliability and durability are critical.
1. Basic Specifications & Parameters
The EN 2.4819 (Hastelloy C276) round bars adhere to strict material and dimensional standards, ensuring consistency in performance and compatibility with engineering requirements.
| Parameter Category | Details |
| Alloy Designation | EN 2.4819 (European Standard); UNS N10276 (American Standard); DIN 1.4529 (German Standard) |
| Diameter Range | 6mm - 100mm (small-diameter range, suitable for precision machining) |
| Standard Length | 6m (custom lengths available upon request, e.g., 3m, 4.5m) |
| Processing State | Hot-rolled (HR) or Cold-finished (CF); CF bars offer higher dimensional accuracy (tolerance: ±0.1mm for diameters ≤50mm) |
| Surface Finish | Mill finish (for general use) or Polished finish (for sanitary/high-purity applications) |
| Chemical Composition | Nickel (Ni): ≥57%; Chromium (Cr): 14.5-16.5%; Molybdenum (Mo): 15-17%; Tungsten (W): 3-4%; Iron (Fe): ≤5%; Carbon (C): ≤0.01%; Silicon (Si): ≤0.08%; Manganese (Mn): ≤1% |
2. Key Mechanical & Corrosion Performance
Hastelloy C276’s performance is defined by its balanced mechanical strength and superior resistance to aggressive media, even at elevated temperatures.
2.1 Mechanical Properties (at Room Temperature, for Cold-Finished Bars)
- Tensile Strength: ≥730 MPa
- Yield Strength (0.2% offset): ≥310 MPa
- Elongation (in 50mm): ≥40%
- Hardness: ≤210 HB (Brinell) / ≤220 HV (Vickers)
Note: Mechanical properties can be adjusted via heat treatment (e.g., solution annealing at 1150-1175°C followed by rapid quenching) to enhance strength for high-stress applications.
2.2 Corrosion Resistance
The alloy’s unique composition (high Mo, Cr, and W content) delivers outstanding resistance to:
- Oxidizing acids: Nitric acid, sulfuric acid (dilute to moderate concentrations).
- Reducing acids: Hydrochloric acid, phosphoric acid, and organic acids (e.g., acetic acid).
- Chloride-induced corrosion: Pitting, crevice corrosion, and stress corrosion cracking (SCC) in seawater, brines, or chloride-rich process streams.
- High-temperature environments: Stable oxidation resistance up to 1040°C (2000°F) in air; maintains strength and corrosion resistance in high-temperature chemical reactors.
3. Equivalent / Similar Grades
Hastelloy C276 is standardized across regions under different designations, ensuring global sourcing compatibility.
| Standard System | Grade Designation | Region | Key Similarity |
| European (EN) | EN 2.4819 | EU, UK | Direct equivalent to Hastelloy C276 |
| American (UNS) | UNS N10276 | USA, Canada | Primary American designation for C276 |
| German (DIN) | DIN 1.4529 | Germany, Europe | Near-equivalent (minor compositional tweaks) |
| Japanese (JIS) | JIS NW2201 | Japan | Equivalent for Asian markets |
| ASTM | ASTM B574 | USA | Specification for nickel-alloy round bars (includes C276/UNS N10276) |
4. Typical Applications
The 6-100mm diameter, 6m length EN 2.4819 round bars are widely used in industries where corrosion resistance and dimensional precision are non-negotiable:
- Chemical Processing: Components for reactors, heat exchangers, valves, and piping (handling acids, solvents, and corrosive intermediates).
- Oil & Gas: Downhole tools, wellhead components, and offshore equipment (resistant to seawater and sour gas environments).
- Pharmaceutical & Food Processing: Sanitary piping, mixing blades, and reactor internals (compliant with high-purity and corrosion-free requirements).
- Pollution Control: Scrubber systems, flue gas desulfurization (FGD) equipment, and wastewater treatment components (resistant to acidic flue gases).
- Aerospace & Power Generation: High-temperature fasteners, turbine components, and combustion system parts (withstands elevated temperatures and oxidative media).
5. Other Common Nickel Alloy Grades
Beyond Hastelloy C276 (EN 2.4819), there are several widely used nickel alloys, each optimized for specific environments:
| Alloy Series | Grade Designation | Key Feature | Typical Applications |
