I think during hardness you could find exact values related to each area (base metal, weld metal, fusion line and HAZ refer to hardness sketch) but in other tests such as tensile you will find a summary of properties for those areas together (that is not good for root cause analysis or developing design or fit for purpose).
Also if any doubt remain after hardness, it is practical that you check values again or doing retest. Also check values in relationship with microstructure which are not practical after destructive tests.

Hi All,
Why NACE is restricting hardness value? Why Not other properties e.g Yield ... etc.
What is the relations between hardness and cracking behaviour ?
Kindly provide your valuable views on this.
Best regards
Vijay Katkar
