Attributed primarily to its remarkable deteriorative properties, CN3MN, is one of the significant Super Austenitic Cast Stainless Steel (SSS). Main application areas of CN3MN are marine constructions and oil wells due to their excellent corrosion resistance and superior toughness. Wrought steel pieces are typically smaller in size and can be heat-treated and cooled rapidly in order to avoid embrittlement. However, in the case of cast CN3MN superaustenitic stainless steel, cooling rate is much slower so the regions suffered from such embrittlement is extended. In this talk we will discuss mechanisms of this embrittlement problem observed in CN3MN cast superaustenitic stainless steels after heat-treatments for relatively short times (less than 30 minutes) through a combined study of mechanical, thermal and microstructure analyses.
