Long- And Short Term Laboratory Testing Of UNS N06985 For OCTG In Extreme Sour Environments

UNS N06985 is a nickel-based alloy with additions of Mo, Cu and W. Because of its high strength and high resistance to stress corrosion cracking (SCC), cold worked UNS N06985 has been extensively used for OCTG (Oil Country Tubular Goods). The SCC initiation has been studied in Cl-H₂S-CO₂ containing sour environments; and the SCC resistance was often evaluated using slow strain rate testing (SSRT) for screening by short-term testing and using tensile or C-ring for verification by long-term autoclave testing exposures¹. UNS N06985 showed high resistance to SCC at high temperatures in elemental sulfur containing environments with moderate chlorides².

NACE TM0177-2024, Laboratory Testing of Metals for Resistance to Sulfide Stress Cracking and Stress Corrosion Cracking in H2S Environments

Product Number: NACE TM0177-2024

Publication Date: 2024

$109.00

This standard addresses the testing of metals for resistance to cracking under the combined action of tensile stress and corrosion in aqueous environments containing hydrogen sulfide (H2S). This phenomenon is generally termed sulfide stress cracking (SSC) when operating at temperatures near or below ambient and stress corrosion cracking (SCC) when operating at higher temperatures. In recognition of the variation in temperature and with different materials, this phenomenon is herein called environmentally assisted cracking (EAC). For the purposes of this standard, EAC includes only SSC, SCC, and hydrogen stress cracking (HSC).
