Hastelloy C-276 is a nickel-molybdenum-chromium superalloy renowned for its exceptional corrosion resistance and high-temperature strength. Its unique composition and specialized processing make it ideal for demanding environments in industries such as chemical processing, oil & gas, marine, and pollution control.

Key Properties of Hastelloy C-276 Coil

Corrosion Resistance

Resists pitting, crevice corrosion, and stress corrosion cracking (SCC).

Performs well in oxidizing and reducing environments, including HCl, H₂SO₄, and seawater.

Excellent resistance to chloride-induced corrosion, making it suitable for marine applications.

High-Temperature Performance

Maintains strength and ductility at elevated temperatures (up to 1900°F / 1040°C).

Resists oxidation and carburization in extreme conditions.

Weldability & Fabrication

Can be welded using TIG, MIG, and SMAW methods without significant loss of corrosion resistance.

Requires proper heat treatment and post-weld annealing to avoid sensitization.

Formability & Machinability

Can be cold-worked and hot-formed but requires specialized techniques due to its high strength.

Machining requires slow speeds, high feed rates, and rigid tooling to avoid work hardening.

Applications of Hastelloy C-276 Coil

Chemical Processing: Reactors, heat exchangers, piping.

Oil & Gas: Downhole equipment, flue gas desulfurization (FGD) systems.

Marine Engineering: Seawater handling components, offshore platforms.

Pollution Control: Scrubbers, waste treatment systems.

Processing Considerations

Requires specialized equipment for rolling, welding, and heat treatment.

Low-carbon version (C-22, C-2000) is available for improved weldability.

Hastelloy C-276 coil is a premium material for extreme environments, offering long-term durability where other alloys fail. Proper handling ensures optimal performance in critical applications.
