Comprehensive Product Datasheet: DIN 2.4819 (Hastelloy® C-276) Nickel Alloy Plate
1. Product Overview
DIN 2.4819 (trade names: Hastelloy® C-276, UNS N10276, W.Nr. 2.4819) is a nickel-molybdenum-chromium superalloy engineered for extreme corrosion resistance. As a solution-strengthened, low-carbon alloy, it excels in oxidizing and reducing environments, making it ideal for critical applications in chemical processing, pollution control, and marine engineering138.
2. Key Chemical Composition
| Element | Composition (wt.%) | Role |
|---|---|---|
| Ni | Balance (~50-60%) | Base matrix, ductility |
| Mo | 15.0-17.0 | Resistance to reducing acids (e.g., HCl, H₂SO₄) |
| Cr | 14.5-16.5 | Oxidation resistance |
| W | 3.0-4.5 | Enhances pitting resistance |
| Fe | 4.0-7.0 | Cost efficiency |
| C, Si | ≤0.02, ≤0.08 | Ultra-low to prevent intergranular corrosion |
| Trace elements (Co, V, Mn, P, S) tightly controlled for purity358. |
3. Outstanding Properties & Performance
3.1 Corrosion Resistance: The Ultimate Shield
-
Acid Resistance: Withstands sulfuric, hydrochloric, phosphoric, and organic acids (e.g., acetic, formic) at concentrations ≤65% and temperatures up to boiling point58.
-
Chloride Immunity: Exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking (SCC) in seawater, brine, and chlorinated solvents14.
-
Unique Capability: One of few alloys suitable for wet chlorine, hydrofluoric acid (HF), and flue gas desulfurization (FGD) scrubbing37.
3.2 Mechanical & Physical Properties
| Property | Value |
|---|---|
| Density | 8.90–9.24 g/cm³ |
| Melting Point | 1325–1370°C |
| Tensile Strength | 690–735 MPa |
| Yield Strength (0.2%) | 285–310 MPa |
| Elongation | ≥40% |
| Hardness (Brinell) | ≤230 HB |
| Maintains strength from cryogenic temperatures to 550°C; avoid prolonged use above 700°C due to aging embrittlement349. |
3.3 Fabrication Advantages
-
Weldability: Compatible with TIG, MIG, plasma arc, and SMAW. No post-weld heat treatment required8.
-
Formability: Excellent cold/hot workability via rolling, forging, and deep drawing68.
4. Target Applications
| Industry | Key Components |
|---|---|
| Chemical Processing | Reactors, evaporators, acid-handling systems |
| Pollution Control | FGD scrubbers, dampers, flue gas reheaters |
| Marine & Offshore | Seawater pipelines, submarine components |
| Pharma/Pulp & Paper | Bleach equipment, waste treatment tanks |
| Energy | Nuclear coolant systems, heat exchangers147 |
5. Sales Advantages & Supply Capabilities
5.1 Competitive Selling Points
-
⛑️ Zero Intergranular Corrosion: Ultra-low C/Si eliminates carbide precipitation in weld heat-affected zones (HAZ), ensuring structural integrity in welded assemblies35.
