Hardness is a function of chemical composition and thermal treatment. Normally HAZ hardness shall be within the range for the grade specified similar to that of basematerial.
HAZ is subjected to different peak temperatures and thermal cycles, hence the Hardness of the HAZ will be higher but shall be controlled by welding conditions.

Hi All,
I'd like to ask a question along these lines as well. If one should compare the hardness of the HAZ with the hardness of the material, what would be the ideal condition of the?

Dear sir,
Why is the Hardness of HAZ higher than that of Weld?
Thanks and Regards,
