PSPP Map for Chloride Stress Corrosion Cracking on 304 Stainless Steel
This paper describes the Process-Structure-Property-Performance (PSPP) map of Chloride stress corrosion cracking (CLSCC) on 304 SS. Applications in the oil and gas industry are exposed to chloride from naturally occurring sources, like raw water (lake), cooling tower water, salt water, etc. High concentrations of chlorides (more than 50ppm) and elevated temperatures (>60 °C) can exacerbate the effect of active loads on a 304 SS member by reagent attack on stress concentrations to induce stress-corrosion-cracking (SCC)". Even though there is much information regarding this process, the industry still has failures, primarily because chlorides appear when they are not anticipated or accounted for, which can result in catastrophic, and financial failures.
