Since alloy N07022 was introduced in 2011 the alloy has seen use as bar for both drilling and completions and as Oil Country Tubular Goods for oil patch applications. This paper summarizes the uses and applications for sour service oil patch and refinery applications. The alloy has been incorporated into the MR-0175/ ISO 15156 document for Materials for Use in H2S-Containing Environments in Oil and Gas Production. Alloy N07022 is resistant to the NACE Level VII Environment with 5 g/L elemental sulfur and to Modified NACE Level VII 25% NaCl + 1000 psi (7000 kPa) CO2 + 1000 psi (7000 kPa) H2S at 550°F (288°C). This makes alloy N07022 the most corrosion resistant alloy contained in NACE MR0175/ ISO 15156. Alloy N07022 mechanical maintains properties over the -300ºF to 500ºF temperature range with stability to 700ºF for >100000 hours for refinery applications. Also alloy N07022 is now included in the MR0103/ ISO 17945 Corrosion Prevention and Control for Oil and Gas Production Petroleum Refining and Gas Processing Industries. Alloy N07022 has been qualified for subsea and marine fastener applications where no other alloy has the strength and corrosion resistance required. This paper reviews the metallurgy mechanical properties and corrosion resistance along with areas of application of the alloy.Keywords: nickel-base alloy high temperature high pressure sour service cold worked nano precipitation-hardened bar oil country tubular goods oil field
