Atmospheric CSCC Threshold Temp For 6Mo

Atmospheric CSCC Threshold Temp For 6Mo

Atmospheric CSCC Threshold Temp For 6Mo

(OP)
We are probably all aware of the universally adopted limit of 60 deg C as the threshold temperature for CSCC of 316/316L stainless steels; however, the limits for 6Mo austenitics are not so readily discernible.  Does anyone using these materials have a specified threshold temperature for CSCC under atmospheric exposure (marine, industrial, whatever)?

RE: Atmospheric CSCC Threshold Temp For 6Mo

I have never seen CSCC in AL-6XN in the lab below 122C.  I have never seen CSCC in a real application below 155C.
