N06975 Alloy G-2 Corrosion Resistance Alloy Pipe For Oilfield

Alloy G-2 (UNS N06975) is a cold hardened nickel-based alloy intended for corrosion resistance to highly sour (H2S) environments with high chloride content, requiring high strength up to 400°F.

The high nickel and molybdenum content of G-2 extends the sour service limits of nickel alloys while also providing excellent resistance to chlorides and dissolved oxygen. It is therefore used for 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 final material selection.

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