329 duplex stainless steel is one of the earliest duplex steels, which allows high carbon content. Exposure to medium high temperatures and slow cooling may cause embrittlement.
Therefore, for s32900, the design stress value will not exceed 260 ° C. The impact value is high at room temperature. However, the ratio and orientation of ferrite in the weld and base metal may significantly affect the toughness at sub zero temperatures.
