Chloride stress corrosion cracking in austenitic stainless
Chloride stress corrosion cracking (CLSCC) is one the most common reasons why austenitic stainless steel pipework and vessels deteriorate in the chemical processing and petrochemical industries. Deterioration by CLSCC can lead to failures that have the potential to release stored energy and/or hazardous substances.

Effect of Long Term Service Exposure on CORROSION
Slow strain rate testing of Type 347 SS in both the service exposed and solution annealed conditions showed susceptibility to stress corrosion cracking in environment containing NaCl + H 2 S, while the alloy did not show susceptibility to SCC in H 2 SO 4 and K 2 S 4 O 6. The long term service exposure did not noticeably influence the SCC susceptibility of Type 347 SS under the tested conditions.

Stress corrosion cracking facts and how to reduce the
The use of material susceptible to stress corrosion cracking (SCC) A precursor of stress corrosion cracking in chloride bearing environments is pitting corrosion, occurring if the stainless steel is not sufficiently resistant to pitting. How to reduce the risk of stress corrosion cracking (SCC) The risk of stress corrosion cracking (SCC) can be minimized through plant and equipment design.

Stress relieving heat treatments for austenitic stainless
The temperature ranges used in stress relieving must avoid sensitising the steel to corrosion or the formation of embrittling precipitates. The low carbon (304L or 316L) or the stabilised (321 or 347) types should not be at risk from corrosion sensitisation during stress relieving treatments.
Stress Corrosion Cracking NACE
Chloride stress corrosion is a type of intergranular corrosion and occurs in austenitic stainless steel under tensile stress in the presence of oxygen, chloride ions, and high temperature. It is thought to start with chromium carbide deposits along grain boundaries that leave the metal open to corrosion. This form of corrosion is controlled by maintaining low chloride ion and oxygen content in the environment and use

Type 347 stainless is an austenitic steel alloy with added Niobium/Columbium which acts as a stabiliser. This makes the alloy suitable for service in aqueous and low temperature environments as the alloy has good resistance to intergranular attack. The alloy also offers good resistance to polythionic acid stress corrosion cracking and is therefore a useful a material for use around reactor plants.

Alloy 347 is a stabilized, austenitic, chromium steel containing columbium which allows for the elimination of carbide precipitation, and, consequently, intergranualr corrosion. Alloy 347 is stabilized by the additions of chromium and tantalum and offers higher creep and stress rupture properties than alloy 304 and 304L which may also be used for exposures where sensitization and intergranualr corrosion are of concern.
