Material Description

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.

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%

Key Mechanical & Corrosion Performance

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.

Corrosion Resistance

The alloy's unique composition (high Mo, Cr, and W content) delivers outstanding resistance to:

Oxidizing acids: 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

Equivalent / Similar Grades

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)

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)
