Hi,
The reason for PWHT for SS316L is having homogenious and Carbide free microstructure. This alloy is an austenitic alloy, so we cannot change its mechanical properties using heat treatment. Solution anealing is carried out aiming to enhance resistance of alloy against intergranular corrosion, happening because of depletion of Cr in this region.
best regards,
Saeid

Hi all,
Anybody know about effect of PWHT on SS-316L (no regarding to corrosion but on mechanical properties only)?
Thanks
Alex Mahoun
