Hardness value for welded joint
Hardness value for welded joint
(OP)
Hi, everyone
Anyone guy telll me the minimum hardness value for welded joint of P355 NL1 EN material?
Relevant standard(EEMUA 190) only shows maximum hardness value. This is our client requirement.
As I know, all hardness value is limited to maximum value not minimum.
Thanks

Requirement for minimum allowable hardness value is the comment from our client.
As mentioned in original thread, reference code just mentions maximum allowable hardness value (248 HV 10).
Client wants to know minimum hardness value on welds(incl. HAZ & base metal) after PWHT.
Thanks

As you mentioned, minimum value as well maximum is also important to ensure mechanical properties don't lower. But, we can't find how much of hardness value is acceptable as minimum in any standard and code application.
For said material, our client has required specific minimum allowable hardness value after pwht
Thus, I hope any guy can tell me applicable reference or specific value that based on reference.
