Avoid stress corrosion cracking of stainless steel

摘要

In hydrocarbon processing industry (HPI) facilities, austenitic stainless steel (SS) is used for several reasons, including: Avoiding iron pickup and maintaining product purity Replacing carbon steel in operating services in which carbon steel is unsuitable, such as high temperature, corrosive fluids, highly toxic materials (HTM), etc.However, austenitic SS is susceptible to stress-corrosion cracking (SCC), mainly through trans-granular stress-corrosion cracking (TGSCC), such as chloride-containing aqueous media.
