Slow Strain Rate Test Method for Screening Corrosion-Resistant Alloys for Stress Corrosion Cracking in Sour Oilfield Service
This standard establishes a slow strain rate (SSR) test method for screening corrosion-resistant alloys (CRAs) (i.e., stainless steels and nickel-based alloys) for resistance to stress corrosion cracking (SCC) at elevated temperatures in sour oilfield production environments. The SSR test, which is relatively short in duration, incorporates a slow, dynamic strain applied at a constant extension rate. This results in acceleration of the initiation of cracking in susceptible materials, thereby simulating rather severe conditions.
