Hastelloy C276 (Alloy 2.4819) sheet and plate is a premium nickel-molybdenum-chromium alloy renowned for its exceptional corrosion resistance in harsh industrial environments. Combined with custom laser cutting services that deliver precise, burr-free cuts to any size, this product meets the diverse needs of high-performance engineering applications. Below is a detailed overview of its key attributes, specifications, and applications:
1. Core Parameters
Hastelloy C276 sheets and plates are manufactured to strict dimensional and compositional standards, ensuring consistency and reliability.
Sheets: 0.1 mm – 6.0 mm; Plates: 6.0 mm – 100.0 mm (custom thicknesses available upon request)
Laser Cutting Capabilities
- Cut size: Any custom size (from small precision components to large plates) - Cutting tolerance: ±0.1 mm (high precision for tight-fit applications) - Edge quality: Burr-free, smooth edges (eliminates post-processing needs) - Cut shapes: Complex geometries (holes, notches, irregular patterns) supported by CAD design
Surface Finish
Standard: Hot-rolled (HR) with mill finish; Optional: Cold-rolled (CR) for smoother surface, polished finish (for hygiene-critical applications)
2. Mechanical & Corrosion Performance
Hastelloy C276’s performance is defined by its robust mechanical strength and unmatched resistance to aggressive media—key reasons it is favored in extreme conditions.
Mechanical Properties (Annealed Condition)
Property
Value (Typical)
Tensile Strength
≥ 720 MPa
Yield Strength (0.2% Offset)
≥ 310 MPa
Elongation (in 50 mm)
≥ 40%
Hardness (Brinell)
≤ 210 HB
Corrosion Resistance (Key Advantage)
Resists uniform corrosion: Excellent performance in sulfuric acid, hydrochloric acid, phosphoric acid, and organic acids (e.g., acetic acid, formic acid).
Chloride stress corrosion cracking (SCC) resistance: Unaffected by chloride-rich environments (e.g., seawater, brines, chemical process streams), a critical advantage over many stainless steels.
Pitting & crevice corrosion resistance: Maintains integrity in stagnant or low-flow conditions where localized corrosion often occurs.
Oxidation resistance: Stable up to 1093°C (2000°F) in air, with minimal scaling or degradation.
3. Manufacturing & Quality Standards
Hastelloy C276 sheets and plates comply with global industry standards to ensure quality, traceability, and compatibility with engineering codes:
Primary Standard: ASTM B575 (Standard Specification for Nickel-Chromium-Molybdenum-Columbium Alloy (UNS N10276) Plate, Sheet, and Strip) – the most widely recognized standard for this alloy in North America and global markets.
Additional Standards:
ASME SB575 (for pressure vessel and boiler applications, adhering to ASME Boiler and Pressure Vessel Code).
DIN EN 10088-1 (European standard, aligning with Alloy 2.4819 designation).
ISO 6208 (International Organization for Standardization, covering nickel alloy plates/sheets for general industrial use).
4. Specifications (Size & Form)
Beyond custom laser-cut dimensions, standard and configurable specifications include:
Width: 1000 mm – 2500 mm (standard); custom widths up to 3000 mm available.
Length: 2000 mm – 6000 mm (standard); cut-to-length or coil form (for thin sheets, 0.1–3.0 mm) supported.
Tolerance: Complies with ASTM B575 Class A (tight dimensional tolerance) for critical applications; Class B available for non-precision uses.
5. Equivalent Grades (Same Alloy, Different Designations)

6. Key Applications
Leveraging its corrosion resistance and customizability, Hastelloy C276 sheets/plates are used in industries requiring long-term reliability in harsh conditions:
Chemical Processing: Reactors, heat exchangers, separators, and piping components for handling acids (sulfuric, hydrochloric) and corrosive intermediates.
Oil & Gas: Downhole tubulars, wellhead components, and offshore platform parts (resistant to seawater and sour gas).
Pharmaceutical & Food Processing: Tanks, mixers, and conveyor systems (complies with hygiene standards and resists organic acids/cleaning agents).
Aerospace & Defense: Engine components and fuel systems (withstands high temperatures and aggressive fuels).
Power Generation: Boiler tubes, heat recovery steam generators (HRSGs) in coal-fired or waste-to-energy plants.
7. Other Hastelloy C276 Product Types
In addition to sheets and plates, Hastelloy C276 is available in a full range of forms to support end-to-end system integration:
Pipes & Tubes: Seamless and welded tubes (per ASTM B622/B751) for fluid transport in corrosive systems.
Fittings: Elbows, tees, reducers, and flanges (per ASTM B366) – compatible with C276 pipes/tubes.
Bars & Rods: Round bars, square bars, and hex rods (per ASTM B574) for machining into valves, fasteners, or shafts.
Wire & Strip: Thin-gauge wire (ASTM B580) and narrow strip for electrical components or precision gaskets.
Welding Consumables: Wires (ERNiCrMo-4) and electrodes (ENiCrMo-4) to ensure welded joints match the base alloy’s corrosion resistance.
