The precipitation-hardenable, sulfidation-resistant, nickel-base alloy, Pyromet® 31, has been extensively evaluated as a candidate for applications in deep sour gas and oil wells. The alloy metallurgy, properties, and characteristics are described and the evaluations in laboratory and field environments that have led to MR-01-75 approval for the alloy are reviewed. Current work to further define the capabilities of Pyromet 31 in sour gas and oil well applications is also outlined.
