Abstract
Embrittlement in austenitic stainless steels may occur as a result of exposure to temperature between 600 C and 900 C. The primary purpose of this investigation was to study the various causes of embrittlement in 304 and 316 Type stainless steels. The potential causes of embrittlement are: (1) Grain boundary carbide precipitation (2) Grain boundary phosphorus segregation (3) Grain boundary martensite formation (4) Sigma phase fonnation
