Trans- Granular Stress Corrosion in Partially Fabricated Austenitic Stainless Steel Items and their Re-Conditioning to make them Suitable for Balance Fabrication

Abstract:

Fabrication of various sub assemblies and items from imported austenitic stainless steel material of SA 240 - 304L (32 mm to 85 mm thick) was started in the year 1990 and work on these assemblies was stopped in 1993 due to unavoidable circumstances. Items and sub-assemblies were either in partially welded / machined or formed condition. Sub assemblies / items were stored in open yard for 13 years after applying plastic peal coating compound and covered with tarpaulin. The storage yard was near to the sea (roll on & off Jetty) as well as next to petrochemical industries. Sub assemblies have seen different extreme weathers conditions, saline and corrosive atmosphere for all these years and during this storage time base material and welded joints were subjected to contamination.
