HASTELLOY G2, N06975, Cold-hardened Nickel-based Alloy

What is G2 N06975?

HASTELLOY Alloy G2 (UNS N06975) is a cold-hardened nickel-based alloy designed to provide exceptional corrosion resistance in highly sour (H2S) environments with high chloride content, while maintaining high strength up to 400°F.

Where is G2 N06975 used?

The high nickel and molybdenum content in HASTELLOY G2 extends the sour service limits of nickel alloys and offers excellent resistance to chlorides and dissolved oxygen.

As a result, this alloy is widely used in downhole tubular components, packers, and other subsurface equipment in severely sour wells with high-pressure and high-temperature (HPHT) conditions, saltwater injection wells, and Acid Gas Injection (AGI) wells. However, all environmental factors, including H2S, CO2, temperature, pH, and chloride concentration, should be considered before making the final material selection.

For sour service applications, HASTELLOY G2 is classified as a type 4d alloy under MR0175/ISO15156, with no restrictions to a partial pressure of H2S below 300°F and resistance to 300 psi H2S at 425°F.
