Factors Affecting CLSCC Chloride Stress Corrosion Cracking
A range of environmental factors have been identified that can affect the development of Chloride Stress Corrosion Cracking CLSCC which include chloride content, temperature, pH and contact with dissimilar metals.
Recent work has also identified the importance of transient conditions such as high temperature excursions. Alloying element content, impurity levels and the degree of cold working are
factors that affect the intrinsic resistance of a particular austenitic stainless steel to CLSCC. A
significant volume of literature has been published on how CLSCC is affected by environmental
factors and by the factors affecting the resistance of specific grades. Part of this work has been
to review published literature to assess the range of factors involved including:
e
Temperature, pH, chloride content, oxygen level humidity
Electrode potential effects, e.g. galvanic coupling and cathodic protection.
Applied and residual stress
Alloying and impurities in the steel
Sensitisation
Cyclic conditions
