A new Ni-base precipitation strengthened alloy has been developed to provide 860 MPa minimum yield strength and an excellent combination of ductility and impact strength. Testing in various corrosive environments has shown that the alloy has excellent stress corrosion and sulfide stress corrosion resistance. A number of commercial heats were melted and processed to establish robust mill processing practice. This paper will talk about the overall alloy development methodology including heat treatment studies to optimize microstructure and target mechanical and corrosion properties to obtain the most cost effective solution to the needs of the oil and gas (O&G) industry.
