Nickel Alloy C276 Precision Strip | Corrosion-Resistant Thin Strip
1. Introduction to Nickel Alloy C276 Precision Strip
Nickel Alloy C276 (also known as Hastelloy® C276, a registered
trademark of Haynes International) precision strip is a
high-performance thin metal product engineered for extreme
corrosion-resistant applications. Composed primarily of nickel (57%
minimum), molybdenum (15-17.5%), chromium (14.5-16.5%), and
tungsten (3-4.5%), with trace amounts of iron, cobalt, carbon, and
silicon, this alloy exhibits exceptional resistance to both
oxidizing and reducing environments—an attribute that sets it apart
from many other nickel-based alloys.
The "precision" in its name refers to its tight manufacturing
tolerances: thickness typically ranges from 0.01 mm to 2.0 mm,
width from 5 mm to 600 mm, and surface finishes (such as 2B, BA, or
polished) tailored to specific application needs. Its thin gauge,
combined with superior mechanical strength (even at elevated
temperatures up to 1093°C/2000°F) and ductility, makes it ideal for
components requiring both corrosion protection and dimensional
accuracy. Unlike standard metal strips, C276 precision strip
undergoes rigorous quality control, including ultrasonic testing,
chemical composition verification, and mechanical property
validation, to ensure consistency in every batch.
2. Key Technical Parameters

4. Typical Applications
Thanks to its corrosion resistance, precision dimensions, and
high-temperature stability, C276 precision strip is widely used in
industries where failure due to corrosion or dimensional inaccuracy
would have severe consequences. Key applications include:
Chemical Processing:
- Gaskets, diaphragms, and thin-walled liners for reactors handling
aggressive chemicals (e.g., sulfuric acid, hydrochloric acid).
- Sensor housings and flow meters that require resistance to chemical
degradation.
Oil & Gas:
- Downhole tool components (e.g., thin-walled sleeves) for offshore
drilling, where exposure to saltwater and high-pressure
hydrocarbons demands extreme corrosion resistance.
- Valve seats and seals in subsea pipelines.
Pharmaceutical & Food Processing:
- Thin strips for sterile equipment (e.g., blender liners, filter
housings) due to its non-reactive properties and ability to
withstand frequent sanitization (via steam or chemicals).
Aerospace & Defense:
- Heat shields and combustion chamber liners for jet engines, as it
retains strength at high temperatures (up to 1093°C).
- Components for missile guidance systems, where precision and
resistance to harsh environments are critical.
Semiconductor Manufacturing:
- Wafer handling equipment (e.g., thin claws, electrostatic chucks)
that requires ultra-clean surfaces and resistance to corrosive
etchants (e.g., hydrofluoric acid).
Environmental Engineering:
- Membrane supports for water treatment plants (e.g., reverse osmosis
systems) and exhaust gas scrubbers, where exposure to chlorides and
acidic solutions is common.
5. Other Nickel Alloy C276 Products
Beyond precision strip, Nickel Alloy C276 is manufactured in
various forms to meet diverse application requirements. These
products leverage the same core corrosion-resistant properties but
are optimized for specific shapes and use cases:
- C276 Plate & Sheet: Thicker than strip (typically 2 mm to 100 mm),
used for pressure vessels, tank liners, and structural components
in chemical plants.
- C276 Pipe & Tube: Seamless or welded, employed in pipelines for
corrosive fluids (e.g., acid transfer lines) and heat exchangers.
- C276 Wire & Foil: Foil (thinner than 0.01 mm) for flexible gaskets
and battery components; wire for thermocouples and electrical
connectors in high-temperature environments.
- C276 Forgings & Castings: Forged parts (e.g., valve bodies, pump
impellers) for heavy-duty industrial equipment; castings for
complex shapes requiring uniform corrosion resistance.
- C276 Fasteners: Bolts, nuts, and washers used to assemble
corrosion-sensitive components, ensuring compatibility with C276
base materials.
