HASTELLOY® C276 UNS N10276
A high-strength superalloy designed for extreme chemical environments, chloride media, strong acids and industrial applications where corrosion is the main operational risk.
A reference alloy against extreme corrosion
HASTELLOY® C276 is used when parts must maintain structural reliability in contact with strong acids, contaminated media, chlorides and highly aggressive industrial environments.
HASTELLOY® C276, also identified as UNS N10276, is a nickel-chromium-molybdenum alloy designed to withstand extremely aggressive chemical environments.
It is one of the most widely used superalloys in the chemical and offshore industries due to its excellent resistance to general corrosion, pitting, crevice corrosion and stress corrosion cracking.
Its balance of nickel, chromium, molybdenum and tungsten makes it suitable for manufacturing critical components exposed to oxidizing media, reducing media and complex service conditions.
Nickel base with chromium, molybdenum and tungsten
| Element | Approximate content |
|---|---|
| Nickel, Ni | Balance |
| Chromium, Cr | 14.5–16.5% |
| Molybdenum, Mo | 15–17% |
| Iron, Fe | 4–7% |
| Tungsten, W | 3–4.5% |
Why choose HASTELLOY® C276

Stress corrosion cracking
Very good performance against stress corrosion cracking under specific service conditions.
Good thermal stability
Typical service temperature up to 1000°C depending on the application, chemical environment and working conditions.
Excellent weldability
Allows manufacturing and joining processes under proper technical control for critical industrial parts.
Components for chemical, marine and offshore environments
HASTELLOY® C276 is used in sectors where corrosion is a critical risk for safety, production and equipment service life.
Demanding superalloy, precise strategy
HASTELLOY® C276 has a high tendency to work-harden, low thermal conductivity and heat generation in the cutting zone.
Recommended to maintain stability, precision and tool life during cutting.
Help control thermal load, surface work-hardening and vibration.
Essential to evacuate heat, improve chip control and reduce tool wear.
Key for technical parts with demanding tolerances and complex geometries.
The strategy must be adapted to geometry, batch size, required finish and final application.
