Please see some extracts from a publication of Metrode, which provides some guidelines on the hardness requirements for grade 92 steel. You may find the same information in ASTM/ASME specifications also. To reduce hardness , additional SR would be necessary.
While performing welding of any CSEF steel(as P-92), it’s advisable to keep Radiography before SR as an optional step depending on the joint thickness, criticality of the component, and many more…. so as to avoid any unpleasant situation as above.
Thanks.

Dear Experts,
I have one situation I have a job of material SA 182 F92. Hardness required for this material is 269 HBW Max. We had weld the F92 to F92 material. After PWHT we got Hardness around 250 HBW. But after Radiography it was one defect and we repair it. Now the Hardness of repaired portion is around 340 HBW. Now how we reduce it. And what is the Hardness limit of F92 Weld joints ?
