本标准建立了一种慢应变速率（SSR）试验方法，用于筛选耐腐蚀合金（CRA）（即不锈钢和镍基合金）在酸性油田生产环境中耐高温应力腐蚀开裂（SCC）的性能。SSR试验持续时间相对较短，包括以恒定延伸率施加的缓慢动态应变。这会加速敏感材料的开裂，从而模拟相当恶劣的条件。本标准规定了试剂、试样、试验设备、基准材料性能的测定、环境和机械试验条件、试验程序以及试验结果的分析和报告。它旨在供实验室调查人员用于筛选耐酸性油田服务中SCC的CRA。本次修订扩大了标准的范围，以解决降水筛选问题- 采用SSR试验方法，用于抗氢致应力开裂（HISC）的硬化镍基合金。

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.The standard specifies reagents, test specimen, test equipment, determination of baseline material properties, environmental and mechanical test conditions, test procedure, and analysis and reporting of test results. It is intended for use by used by laboratory investigators for screening CRAs for resistance to SCC in sour oilfield service.This revision extends the scope of the standard to address the screening of precipitation-hardened nickel-based alloys for resistance to hydrogen induced stress cracking (HISC) using the SSR test method.
