Check the temperature; if it’s not high, it probably isn’t necessary. Also, a stress corrosion test needs to be conducted, but not at the intergranular level

It is needed. Refer to clause 6.1.2-1-（4） of the standard HG/T20581-2011.

Provide the temperature; generally, no action is required if it is below 80 degrees
